The home page shows the method for converting DataTable to Json:

1 public static string TableToJson (DataTable dt) 2 {3 List <Dictionary <string, object> list = new List <Dictionary <string, object> (); 4 foreach (DataRow dr in dt. rows) // creates a new Dictionary <string, object> for each row, and adds each column of the row to the Dictionary 5 {6 Dictionary <string, object> result = new Dictionary <string, object> (); 7 foreach (DataColumn dc in dt. columns) 8 {9 result. add (dc. columnName, dr [dc]. toString (); 10} 11 list. add (result); 12} 13 return ToJson (list); // call the Serializer method 14}

1 /// <summary> 2 /// convert the set to json 3 /// </summary> 4 /// <param name = "d"> </param> 5 /// <returns> </returns> 6 public static string ToJson (object d) 7 {8 JavaScriptSerializer jss = new JavaScriptSerializer (); 9 return jss. serialize (d); 10}

 

Specific conversion instance:
