Asp.net (C #) parses Json class code

This article resolves the following data into data that can be used by. Net. The returned data except the header is variable, that is, the structure is not fixed. The generated able is selected by the user.
The Json data format is as follows:
Copy codeThe Code is as follows:
{"DataSet ":{
"Header ":{
"ReturnCode": "0 ",
"ErrorInfo": "HTTP request error ",
"Version": "V1.0R010 ",
"TotalRows": "2000 ",
"ReturnRows": "20"
},
"FieldDefine ":{
"AssetId": "string ",
"ServerIdcId": "int ",
"InputTime": "datetime"

"Data": {"row ":[
