Json与XML辅助类（读写存操作）

数据类

保存解析文件的路径 和文件的内容

    public class ConfigNode    {        protected string filePath;     //文件的路径        protected string contextRead;  //解析出来的文件内容    }//这里文件的路径  写绝对路径 例如：C:\Users\Administrator\Desktop\TestJson.json//如果写相对路径，代表该文件存放在bin/Debug文件夹下## Json通用类 ##

public class JsonHelper ：ConfigNode
{
public T dataRead; //T类型的数据对象

    public JsonHelper() {    }    public JsonHelper(string filePath)    {        this.filePath = filePath;    }    public void Dispose()    {        throw new NotImplementedException();    }    public void GetConfigData()    {        throw new NotImplementedException();    }    public void Init()    {        Read();    }

//加载文件
public bool LoadFile(string lfilePath)
{
if (!File.Exists(lfilePath)) throw new Exception(“file load fail”);
try
{
using (StreamReader reader = File.OpenText(lfilePath) )
{
this.contextRead= reader.ReadToEnd();
}
}
catch (Exception e) {
throw new Exception(“file read fail”);
}
return true;
}

//将加载出来的文件内容转为T类型对象
public virtual void Read()
{
if(LoadFile(this.filePath))
dataRead= JsonMapper.ToObject(this.contextRead);
}

//将T类型数据对象保存在新路径
public void Save(string sfilePath = “newfile.json”)
{
string json = JsonMapper.ToJson(this.dataRead);
try
{
using (var sw = new StreamWriter(sfilePath,true))
{
sw.Write(json);
}
}
catch (Exception e)
{
throw new Exception(“file save fail”); ;
}
}

//将T类型数据对象 写入默认的文件中
public void Write(object newData)
{
if (!File.Exists(this.filePath)) throw new Exception(“file load fail”);
try {
using (var sw = new StreamWriter(this.filePath, true)) {
string json = JsonMapper.ToJson(newData);
sw.Write(json);
}
}
catch (Exception e) {
throw new Exception(“file write fail”);
}
}
}

XML同用类

之前写的

public T dataRead;

    public XmlHelper()    {    }    public XmlHelper(string filePath)    {        this.filePath = filePath;    }    public void Dispose()    {        throw new NotImplementedException();    }    public void GetConfigData()    {    }    public void Init()    {        Read();    }

//加载文件
public bool LoadFile(string lfilePath)
{
if (!File.Exists(lfilePath)) throw new Exception(“file load fail”);
try {
using (StreamReader reader = File.OpenText(lfilePath)) {
this.contextRead = reader.ReadToEnd();
}
}
catch (Exception e) {
throw new Exception(“file read fail”);
}
return true;
}

//将XML文件转为对象（反序列化）
public void Read()
{
if (LoadFile(this.filePath))
{
using (StreamReader reader = new StreamReader(this.filePath))
{
XmlSerializer xs = new XmlSerializer(typeof (T));
dataRead=(T)xs.Deserialize(reader);
}
}
}

//保存xml文件到新路径
public void Save(string sfilePath = “newfile.xml”)
{
if (LoadFile(sfilePath))
{
var sw = new StreamWriter(sfilePath, true);
sw.Write(this.contextRead);
}
}

//将新的数据对象 写入xml文件中
public void Write(object newData)
{
if (LoadFile(this.filePath))
{
try {
using (var stream = new StreamWriter(this.filePath, true)) {

                    StringWriter sw = new StringWriter();                    XmlSerializer s = new XmlSerializer(newData.GetType());                    s.Serialize(sw, newData);                    string myStr = sw.ToString();                    if (this.contextRead != "") {                        int i = sw.ToString().IndexOf("<" + newData.GetType().Name);                        int j = sw.ToString().IndexOf(">", i) + 3;                        myStr = myStr.Remove(0, j);                        int k = this.contextRead.IndexOf("</" + newData.GetType().Name);                        this.contextRead = this.contextRead.Remove(k);                        this.contextRead += myStr;                        stream.Close();                        using (var newstream = new StreamWriter(this.filePath, false))                        {                            newstream.Write(this.contextRead);                        }                    }                    else {                        this.contextRead = myStr;                        stream.Write(this.contextRead);                         }                }            }            catch (Exception e) {                throw new Exception("file write fail");            }        }
