本文实例讲述了C#实现实体类与字符串互相转换的方法。分享给大家供大家参考。具体实现方法如下：

using System;using System.Collections.Generic;using System.Text;namespace PackDLL.Data.ConvertData{ /// <summary> /// 实体类、字符串互相转换 /// </summary> public class PackReflectionEntity<T> {  /// <summary>  /// 将实体类通过反射组装成字符串  /// </summary>  /// <param name="t">实体类</param>  /// <returns>组装的字符串</returns>  public static string GetEntityToString(T t)  {   System.Text.StringBuilder sb = new StringBuilder();   Type type = t.GetType();   System.Reflection.PropertyInfo[] propertyInfos = type.GetProperties();   for (int i = 0; i < propertyInfos.Length; i++)   {    sb.Append(propertyInfos[i].Name + ":" + propertyInfos[i].GetValue(t, null) + ",");   }   return sb.ToString().TrimEnd(new char[] { ',' });  }  /// <summary>  /// 将反射得到字符串转换为对象  /// </summary>  /// <param name="str">反射得到的字符串</param>  /// <returns>实体类</returns>  public static T GetEntityStringToEntity(string str)  {   string[] array = str.Split(',');   string[] temp = null;   Dictionary<string, string> dictionary = new Dictionary<string, string>();   foreach (string s in array)   {    temp = s.Split(':');    dictionary.Add(temp[0], temp[1]);   }   System.Reflection.Assembly assembly = System.Reflection.Assembly.GetAssembly(typeof(T));   T entry = (T)assembly.CreateInstance(typeof(T).FullName);   System.Text.StringBuilder sb = new StringBuilder();   Type type = entry.GetType();   System.Reflection.PropertyInfo[] propertyInfos = type.GetProperties();   for (int i = 0; i < propertyInfos.Length; i++)   {    foreach (string key in dictionary.Keys)    {     if (propertyInfos[i].Name == key.ToString())     {      propertyInfos[i].SetValue(entry, GetObject(propertyInfos[i], dictionary[key]), null);      break;     }    }   }   return entry;  }  /// <summary>  /// 转换值的类型  /// </summary>  /// <param name="p"></param>  /// <param name="value"></param>  /// <returns></returns>  static object GetObject(System.Reflection.PropertyInfo p, string value)  {   switch (p.PropertyType.Name.ToString().ToLower())   {    case "int16":     return Convert.ToInt16(value);    case "int32":     return Convert.ToInt32(value);    case "int64":     return Convert.ToInt64(value);    case "string":     return Convert.ToString(value);    case "datetime":     return Convert.ToDateTime(value);    case "boolean":     return Convert.ToBoolean(value);    case "char":     return Convert.ToChar(value);    case "double":     return Convert.ToDouble(value);    default:     return value;   }  } }}

希望本文所述对大家的C#程序设计有所帮助。
