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;

}

}

demo页面的cs文件代码：

using System;

using System.Collections;

using System.Configuration;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.HtmlControls;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Xml.Linq;

public partial class _fan_xuliehua : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

//序列化

DataTable dt = new DataTable();

dt.Columns.Add("ID");

dt.Columns.Add("Name");

dt.Rows.Add(new object[] { 1, "first" });

dt.Rows.Add(new object[] { 2, "second" });

string result = SerializeUtilities.Serialize(dt);

Response.Write(result);

//反序列化

string mystr = result;

DataTable _resDT = new DataTable();

_resDT = (DataTable)SerializeUtilities.Desrialize(_resDT, mystr);

Response.Write("<br>反序列化结果<br>" + _resDT.Rows[0][0].ToString() + ":" +_resDT.Rows[0][1].ToString() + "<br>");

Response.Write(_resDT.Rows[1][0].ToString() + ":" + _resDT.Rows[1][1].ToString() + "<br>");

}

}
