自己写的输出xml和json的几个方法，和WebService,jquery ajax配合用

using System.Xml;
using System.Data.SqlClient;
using System.Collections;

WebService直接这么输出

-----------------------------------------------------------------------

json： pz_xmljson xj = new pz_xmljson();

Context.Response.Write(xj.toJson("value", tmp));  //xj.jsonLoad(SqlDataReader sdr)
Context.Response.End();

 

jquery  ajax这么拿值

-----------------------------------------------------------------------

 

$.ajax({
url: "WebService.asmx/******",
type: "POST",
data: {
receiverid: 。。。。,
key: 。。。。

},
dataType: "json",
success: function(result) {

result[0].value  。。。。。

}

多个值的话用

$.each(result, function(i, n) {

n.Name。。。。

n.ID。。。。。

n.***。。。。。

}
