 Namespace  Maticsoft. model {  ///   <Summary>      ///  Return JSON attributes  ///   </Summary>  [Serializable]  Public   Class Backinfo <t>{  ///   <Summary>          ///  Status  ///   </Summary>          Public String result { Get ; Set  ;}  ///   <Summary>          ///  Returned data  ///  </Summary>          Public List <t> info { Get ; Set  ;}}  ///   <Summary>      ///  Return JSON attributes  ///   </Summary>  [Serializable]  Public   Class Backdatatable <t> { ///   <Summary>          ///  Status  ///   </Summary>          Public String result { Get ; Set  ;}  ///   <Summary>          ///  Returned data  ///   </Summary>         Public T info { Get ; Set  ;}}} 

Serialize JSON

Classifyinfo = JSON. jsoninfo ("200", jsonconvert. serializeobject (DT); // The dt here is the datatable

 

Deserializing josn

View code

String jsondata = getpage ( "  HTTP: /localhost: 3448/APP/API. aspx  " , "  Action = classifylist & parentid = 2  " ); Maticsoft. model. backdatatable <Datatable> backinfo = (maticsoft. model. backdatatable <datatable>) jsonconvert. deserializeobject (jsondata, Typeof (Maticsoft. model. backdatatable <datatable> ));  If (Backinfo. Result! = "  200  "  ){  //  Failed  } Datatable dt =Backinfo.info;  This . Dropdownlist3.datasource = DT;  This . Dropdownlist3.datatextfield = "  Name  "  ;  This . Dropdownlist3.datavaluefield = "  CID  "  ;  This . Dropdownlist3.databind (); maticsoft. model. backdatatable <List <model. iphone_classify> backinfo1 = (Maticsoft. model. backdatatable <List <model. iphone_classify> ) Jsonconvert. deserializeobject (jsondata,  Typeof (Maticsoft. model. backdatatable <list <model. iphone_classify> ));  If (Backinfo1.result! = "  200  "  ){ //  Failed  }  /*  List <model. iphone_classify> classify = backinfo1.info; this. dropdownlist3.datasource = classify; this. dropdownlist3.datatextfield = "name"; this. Attributes = "CID"; this. dropdownlist3.databind ();  */  Maticsoft. model. backinfo <Model. iphone_classify> backinfo2 = (maticsoft. model. backinfo <model. iphone_classify> ) Jsonconvert. deserializeobject (jsondata,  Typeof (Maticsoft. model. backinfo <model. iphone_classify> ));  If (Backinfo2.result! = "  200  "  ){  //  Failed  }  /* List <model. iphone_classify> classify = backinfo2.info; this. dropdownlist3.datasource = classify; this. dropdownlist3.datatextfield = "name"; this. Attributes = "CID"; this. dropdownlist3.databind ();  */ 

If the serialized JSON directly uses a datatable, The deserialization directly uses

Datatable dt = (datatable) jsonconvert. deserializeobject <datatable> (jsondata );
