前言
趁时间没事可做，今天下午索性做些无聊的事情。
1.根据规则将搜索表单内提交的有效数据封装成搜索字符串返回
form表单提交时，后台可以直接接受表单提交的数据，但有时我们如果要根据自己的需求去接受对应的控件内容，这时我们就要重新编译net内部的数据。以下代码是对筛选条件的处理。
/// <summary> /// 根据规则将搜索表单内提交的有效数据封装成搜索字符串返回 /// </summary> /// <param name="httpRequest">Request对象</param> /// <returns>搜索字符串</returns> public string GetQueryCondition() { string wheres = " 1=1 "; string[] whereKeys =Request.Form.AllKeys; foreach (string curWhere in whereKeys.Where(curWhere => Request.Form[curWhere] != null)) { Debug.Assert(curWhere != null, "curWhere != null"); if (curWhere.Trim().Equals(("X-Requested-With").Trim()) || Request.Form[curWhere] == string.Empty || Request.Form[curWhere] == null) continue; if (CheckForm(Request.Form[curWhere])) { wheres = wheres + " and 1=2"; continue; } if (curWhere.IndexOf("_TInt", System.StringComparison.Ordinal) > 0) wheres = wheres + " and " + curWhere.Substring(0, curWhere.Length - 5) + "=" + Request.Form[curWhere]; else if (curWhere.IndexOf("_TDateBegin", System.StringComparison.Ordinal) > 0) { } else if (curWhere.IndexOf("_TString", System.StringComparison.Ordinal) > 0) wheres = wheres + " and " + curWhere.Substring(0, curWhere.Length - 8) + "='" + Request.Form[curWhere]+"'"; else wheres = wheres + " and charindex('" + Request.Form[curWhere] + "'," + curWhere + ")>0"; } return wheres; } /// <summary> /// 查看提交表单(参数)是否包含非法字符 2014-01-14 JiYanan /// </summary> /// <param name="txt">表单(参数)值</param> /// <returns>true包含非法字符 false不包含非法字符</returns> public bool CheckForm(string txt) { //去掉了- string keyWords = "exec1xp_1sp_1declare1cmd1and1insert1select1delete1update1chr1mid1master1or1truncate1char1declare1join1union1@1;1(1)1[1]1{1}1%1*1'1!1<1>1=1^1--1+1/10x1|"; string[] keyWordsArr = keyWords.Split('1'); txt = txt.ToLower(); foreach (string words in keyWordsArr) { if (txt.IndexOf(words) > -1) { return true; } } return false; }
2.返回类（接口转为json传递的时候使用）
异步调用后台方法，挥着编写接口的时候，我们一般都会希望我们的返回值是一个json,我一般会把这个json定义如下err,msg,data.其中err为错误编码，msg为错误信息，data就是对应的数据集。其中data我们可以根据自己的需求去定义data类型。一直器用起来方便。
using Dictionary;using Dispose;using Newtonsoft.Json;using System;using System.Collections.Generic;namespace StrokeInterface{ /// <summary> /// 接口通用返回父类 /// </summary> internal class InterfaceResultBase { /// <summary> /// 错误号 /// </summary> public int Err { get;

} /// <summary> /// 为子类提供通用加密方法 /// </summary> /// <param name="data">已AES加密的Data</param> /// <returns></returns> protected string ToJsonByAes_Base(AESHelper aes, object obj) { string str = JsonConvert.SerializeObject(obj);

4.mvc 分页操作
4.1.后台数据处理
4.1.1.分页应该算是所有系统中均会有的一个功能，一下是一个项目中用到的分页方法。
/// <summary> /// 获取grid部分的内容wheres条件 /// </summary> /// <typeparam name="T">泛型类型(实体类类型)</typeparam> /// <param name="getListCount">获取数据数量的方法委托</param> /// <param name="getList">获取当前页的数据方法委托 </param> /// <param name="prows">每页数据量</param> /// <param name="wheres">where 条件</param> /// <param name="orders">排序字段</param> /// <param name="controllerName">要获取数据的局部视图名(与当前的视图名相同即可)</param> /// <returns></returns> public ActionResult PartialListData<T>(GetListCount getListCount, GetList<T> getList, int prows,string wheres, string orders, string controllerName) { int count = getListCount(wheres); int pageIndex = 1; if (Request.QueryString["pageIndex"] != null) int.TryParse(Request.QueryString["pageIndex"], out pageIndex); IList<T> list = getList(prows, pageIndex, wheres, orders); ViewBag.pageCurren = pageIndex; ViewBag.pageCount = count / 10 == 0 ? count % 10 == 0 ? 0 : 1 : count % 10 == 0 ? count / 10 : count / 10 + 1; ViewBag.dataCount = count; return PartialView(controllerName, list); }
4.1.2定义以上参数GetListCount 参数以获得分页数据数量
/// <summary> /// 获取数据数量的方法委托 /// </summary> /// <param name="wheres">where条件</param> /// <returns></returns> public delegate int GetListCount(string wheres);
4.1.3.定义参数委托获取线束数据集
/// <summary> /// 获取当前页的数据方法委托 /// </summary> /// <typeparam name="T">泛型类型(实体类类型)</typeparam> /// <param name="prows">每页数据量</param> /// <param name="pages">页码</param> /// <param name="wheres">where条件</param> /// <param name="orders">排序字段</param> /// <returns>数据泛型集合</returns> public delegate IList<T> GetList<T>(int prows, int pages, string wheres, string orders);
4.2 前台页面处理
4.2.1.前台脚本
<script language="javascript" type="text/javascript"> var pageCount = @{@Html.Raw(@ViewBag.pageCount+";");} function ChangeUrl() { var indexValue = $("#pageIndex").attr("value"); if (isNaN(indexValue)) { $("#pageIndex").attr("value", ""); } else { if (indexValue > pageCount) { parent.extAlert("页码超出索引"); $("#pageIndex").attr("value", ""); } else if (indexValue < 1) { parent.extAlert("页码无效，请输入大于0的合法页码数"); $("#pageIndex").attr("value", ""); } else { $("#searchFrom").attr("action", "@{@Html.Raw(ViewBag.SearchConUrl);}pageIndex=" + indexValue); $("#searchFrom").submit(); } } } //页面加载事件 $(function () { $("#pageLi>ul>li").click(function () { $("#searchFrom").attr("action", "@{@Html.Raw(ViewBag.SearchConUrl);}pageIndex=" + $(this).attr("data-pageIndex")); $("#searchFrom").submit(); }); });</script>
4.2.2.html布局处理
<div class="box-footer no-padding"> <div class="mailbox-controls"> <div class="pull-right"> <div style="" id="pageLi"> <div style="float:right;"> <span style="float: right; margin: 9px 16px 5px 10px; font-size: 16px">共<font style="font-weight:bolder;">@ViewBag.pageCount</font>页/共<font style="font-weight:bolder;">@(ViewBag.dataCount)</font>条</span> </div> <ul class="pagination" style="margin: 5px;"> <li data-pageIndex="1"> <a href="javascript:void(0);">首页</a> </li> @{ int prev = ViewBag.pageCurren > 1 ?

public class ValidateHelper { /// <summary> /// 验证电话号码 /// </summary> /// <param name="txt"></param> /// <returns></returns> public static string ValidateTel(string txt) { if (String.IsNullOrEmpty(txt)) return "请输入座机号码！"; bool b = Regex.IsMatch(txt, @"^((\d{7,8})|(\d{4}|\d{3})-(\d{7,8})|(\d{4}|\d{3})-(\d{7,8})-(\d{4}|\d{3}|\d{2}|\d{1})|(\d{7,8})-(\d{4}|\d{3}|\d{2}|\d{1}))$"); if (!b) return "座机号码格式错误！"; return ""; } /// <summary> /// 验证网址 /// </summary> /// <param name="txt"></param> /// <returns></returns> public static string ValidateURL(string txt) { if (String.IsNullOrEmpty(txt)) return "请输入网址！"; bool b = Regex.IsMatch(txt, @"^((http|https)://)?(www.)?[a-z0-9\.]+(\.(com|net|cn|com\.cn|com\.net|net\.cn))(/[^\s\n]*)?$"); if (!b) return "网址格式错误！"; return ""; } /// <summary> /// 验证手机号码 /// </summary> /// <param name="txt"></param> /// <returns></returns> public static string ValidatePhone(string txt) { if (String.IsNullOrEmpty(txt)) return "请输入手机号码！"; bool b = Regex.IsMatch(txt, @"^1[3,4,5,7,8]\d{9}"); if (!b) return "手机号码格式错误！"; return ""; } /// <summary> /// 验证邮编 /// </summary> /// <param name="txt"></param> /// <returns></returns> public static string ValidateZIP(string txt) { if (String.IsNullOrEmpty(txt)) return "请输入邮编！"; bool b = Regex.IsMatch(txt, @"^[1-9]\d{5}$"); if (!b) return "邮编格式错误！"; return ""; } /// <summary> /// 验证邮箱 /// </summary> /// <param name="txt"></param> /// <returns></returns> public static string ValidateEmail(string txt) { if (String.IsNullOrEmpty(txt)) return "请输入邮箱账号！"; bool b = Regex.IsMatch(txt, @"^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$"); if (!b) return "邮箱格式错误！"; return ""; } /// <summary> /// 18位身份证号码验证 /// </summary> /// <param name="card">身份证号码</param> /// <returns>Error：格式错误 ""：格式正确</returns> public static string CheckIDCard18(string card) { if (String.IsNullOrEmpty(card)) return "请输入身份证号码！"; if (card.Length != 18) return "身份证号码格式错误！"; if (!Regex.IsMatch(card, @"^\d{17}(\d|X|x)$")) return "身份证号码格式错误！"; long n = 0; if (long.TryParse(card.Remove(17), out n) == false || n < Math.Pow(10, 16) || long.TryParse(card.Replace('x', '0').Replace('X', '0'), out n) == false) { return "身份证号码格式错误！"; } string address = "11x22x35x44x53x12x23x36x45x54x13x31x37x46x61x14x32x41x50x62x15x33x42x51x63x21x34x43x52x64x65x71x81x82x91"; if (address.IndexOf(card.Remove(2)) == -1) { return "身份证号码格式错误！";// "省份验证"; } string birth = card.Substring(6, 8).Insert(6, "-").Insert(4, "-"); DateTime time = new DateTime(); if (DateTime.TryParse(birth, out time) == false) { return "身份证号码格式错误！";//"生日验证"; } string[] arrVarifyCode = ("1,0,x,9,8,7,6,5,4,3,2").Split(','); string[] Wi = ("7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2").Split(','); char[] Ai = card.Remove(17).ToCharArray(); int sum = 0; for (int i = 0; i < 17; i++) { sum += int.Parse(Wi[i]) * int.Parse(Ai[i].ToString()); } int y = -1; Math.DivRem(sum, 11, out y); if (arrVarifyCode[y] != card.Substring(17, 1).ToLower()) { return "身份证号码格式错误！";//校验码验证 } //return card;//符合GB11643-1999标准 return ""; } }
8.文件检测
项目中有一个这样的需求：当文档中的文件有一个文件进行了更改，这时要获取这个文件的内容，该怎么处理的，这个需求当时就想用事件进行处理，但搜索了一下，发现原来本身c#就有这样的事件监测。代码如下：
public class FileSystemWatcherHelper { private FileSystemWatcher watcher; ILogger logger = new Logger4Net("readFiles"); public void OnStart() { if (watcher == null) { watcher = new System.IO.FileSystemWatcher(); watcher.Path = ReadFiles.GetPath(); watcher.IncludeSubdirectories = true; //watcher.Filter = "*.dat"; watcher.Created += new FileSystemEventHandler(OnFileCreated); watcher.EnableRaisingEvents = true; } } /// <summary> /// 暂停监测 /// </summary> public void OnStop() { // TODO: 在此处添加代码以执行停止服务所需的关闭操作。 if (watcher != null) { watcher.EnableRaisingEvents = false; watcher.Dispose(); } } /// <summary> /// 监测到新文件的处理程序 /// </summary> /// <param name="source"></param> /// <param name="e"></param> public void OnFileCreated(Object source, FileSystemEventArgs e) { logger.Trace("开始执行读取文件"+ e.FullPath); if (File.Exists(e.FullPath)) { //解析新增加的文件 ReadFiles.ReadFile(e.FullPath); } } }}
9.读取文件
在项目中读取一个不断变动的文件，把数据导入数据库，这就是下面这个类的内容，和上面文件检测结合，就会有一个不错的业务流程。
public class FileSystemWatcherHelper { private FileSystemWatcher watcher; ILogger logger = new Logger4Net("readFiles"); public void OnStart() { if (watcher == null) { watcher = new System.IO.FileSystemWatcher(); watcher.Path = ReadFiles.GetPath(); watcher.IncludeSubdirectories = true; //watcher.Filter = "*.dat"; watcher.Created += new FileSystemEventHandler(OnFileCreated); watcher.EnableRaisingEvents = true; } } /// <summary> /// 暂停监测 /// </summary> public void OnStop() { // TODO: 在此处添加代码以执行停止服务所需的关闭操作。 if (watcher != null) { watcher.EnableRaisingEvents = false; watcher.Dispose(); } } /// <summary> /// 监测到新文件的处理程序 /// </summary> /// <param name="source"></param> /// <param name="e"></param> public void OnFileCreated(Object source, FileSystemEventArgs e) { logger.Trace("开始执行读取文件"+ e.FullPath); if (File.Exists(e.FullPath)) { //解析新增加的文件 ReadFiles.ReadFile(e.FullPath); } } }}
10.文件（夹）压缩解压操作
public class ZipFileControl { #region 压缩文件夹,支持递归 /// <summary> /// 压缩文件夹 /// </summary> /// <param name="dir">待压缩的文件夹</param> /// <param name="targetFileName">压缩后文件路径（包括文件名）</param> /// <param name="recursive">是否递归压缩</param> /// <returns></returns> public bool Compress(string dir, string targetFileName, bool recursive) { //如果已经存在目标文件，询问用户是否覆盖 if (File.Exists(targetFileName)) { // if (!_ProcessOverwrite(targetFileName)) return false;
