asp.net(C#)解析Json的类代码

复制代码 代码如下:

｛"dataSet":{
"header":{
"returnCode":"0",
"errorInfo":"HTTP请求错误",
"version":"V1.0R010",
"totalRows":"2000",
"returnRows":"20"
},
"fieldDefine":{
"assetId":"string",
"serverIdcId":"int",
"inputTime":"datetime"
},
"data":{"row":[
{
"AssetId":"TCNS2006888",
"ServerIdcId":"1",
"InputTime":"2008-12-12"
},
{
"AssetId":"TCNS2006889",
"ServerIdcId":"2",
"InputTime":"2008-1-1"
}
]}
}
}
