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;
???? }

}
