<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<title>无标题页</title>

<script src="ExtJs/ext-base.js" type="text/javascript"></script>

<script src="ExtJs/ext-all.js" type="text/javascript"></script>

</head>

<body>

<input id="Button1" onclick="getValue();" type="button" value="返回" />

<textarea id="log" cols="40" rows="10"></textarea>

</body>

</html>

然后我们加入要引用的ext-base.js和ext-all.js两个ExtJs文件,这两个文件需要读者到www.extjs.com去下载.

接下来我们创建一个test.asmx文件,代码如下:

using System;

using System.Collections;

using System.ComponentModel;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.Xml.Linq;

using System.Web.Script.Services;

using System.Collections.Generic;

using System.ServiceModel.Web;

using System.ServiceModel.Dispatcher;

using Component;

namespace WebApplication1

接下来创建一个ExtendMethod.cs文件,存放Json序列化的扩展方法

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Web.Script.Serialization;

using System.Collections;

using System.Reflection;

namespace Component

...{

public static class ExtendMethod

...{

/**//// <summary>

/// 返回Json序列

/// parms字典

/// Key:Json对象名

/// Value:Json对象值

/// </summary>

/// <param name="This"></param>

/// <param name="parms">需要加入的对象</param>

/// <returns></returns>

public static string toJson(this object This,Dictionary<string,object> parms)

...{

JavaScriptSerializer json = new JavaScriptSerializer();

var ds = new ...{ source=This};

Dictionary<object,object> dic = new Dictionary<object,object>();

dic.Add("source",This);

foreach (KeyValuePair<string, object> key in parms)

...{

dic.Add(key.Key,key.Value);

}

return json.Serialize(dic);

}

/**//// <summary>

/// 返回Json序列

/// parms:加入的对象将与this对象同级

/// 未完成

/// </summary>

/// <param name="This"></param>

/// <param name="parms">需要加入的对象</param>

/// <returns></returns>

public static string toJson(this object This, params object[] parms)

...{

JavaScriptSerializer json = new JavaScriptSerializer();

Dictionary<string, object> dic = new Dictionary<string, object>();

dic.Add("source", This);

foreach (object i in parms)

...{

Type t = i.GetType();

PropertyInfo[] myproperties = t.GetProperties();

dic.Add(myproperties[0].Name, myproperties[0].GetValue(i, null));

}

return json.Serialize(dic);

}
