c#将对象序列化为字符串和将字符串反序列化为对象

asp.net开发中，页面间传值最长用到的是url显式传参，session，application和cookie传值等。对于复杂对象页面传值，如果不考虑性能影响的话，通常可以使用session或者application。那么页面间如何通过url传递复杂对象呢？正像标题说的那样，对象 -->字符串，然后在目标页面再将从url参数得到的(字符串-->对象)。这个过程可以用下面的代码来实现：

 

using System;using System.Runtime.Serialization;using System.Runtime.Serialization.Formatters.Binary;using System.IO;

/// <summary>///SerializeUtilities 的摘要说明/// </summary>public class SerializeUtilities{ public SerializeUtilities() {  //  //TODO: 在此处添加构造函数逻辑  // }

    /// <summary>     /// 序列化 对象到字符串     /// </summary>     /// <param name="obj">泛型对象</param>     /// <returns>序列化后的字符串</returns>     public static string Serialize<T>(T obj)     {         try         {             IFormatter formatter = new BinaryFormatter();             MemoryStream stream = new MemoryStream();             formatter.Serialize(stream, obj);             stream.Position = 0;             byte[] buffer = new byte[stream.Length];             stream.Read(buffer, 0, buffer.Length);             stream.Flush();             stream.Close();             return Convert.ToBase64String(buffer);         }         catch (Exception ex)         {             throw new Exception("序列化失败,原因:" + ex.Message);         }     }

     /// <summary>     /// 反序列化 字符串到对象     /// </summary>     /// <param name="obj">泛型对象</param>     /// <param name="str">要转换为对象的字符串</param>     /// <returns>反序列化出来的对象</returns>     public static T Desrialize<T>(T obj, string str)     {         try         {             obj = default(T);             IFormatter formatter = new BinaryFormatter();             byte[] buffer = Convert.FromBase64String(str);             MemoryStream stream = new MemoryStream(buffer);             obj = (T)formatter.Deserialize(stream);             stream.Flush();             stream.Close();         }         catch (Exception ex)         {             throw new Exception("反序列化失败,原因:" + ex.Message);         }         return obj;     }

}
