如何使用json.net将c＃通用列表转换为json？

我正在将我的数据表转换为c＃通用列表。

DataTable dt = mydata(); List list = dt.AsEnumerable().ToList(); 

现在我如何使用json.net将此list转换为json？ 任何建议。

json格式的样本应该是这样的，

 {"Table" : [{"userid" : "1","name" : "xavyTechnologies","designation" : "", "phone" : "9999999999","email" : "[e-mail]","role" : "Admin","empId" : "", "reportingto" : ""},{"userid" : "2","name" : "chendurpandian","designation" : "softwaredeveloper","phone" : "9566643707","email" : "[e-mail]", "role" : "Super User","empId" : "1","reportingto" : "xavyTechnologies"}, {"userid" : "3","name" : "sabarinathan","designation" : "marketer","phone" : "66666666666","email" : "[e-mail]","role" : "User", "empId" : "2","reportingto" : "chendurpandian"}]} 

Answer 1

这是一个例子：

 using System; using System.Data; using Newtonsoft.Json.Linq; class Test { static void Main() { DataTable table = new DataTable(); table.Columns.Add("userid"); table.Columns.Add("phone"); table.Columns.Add("email"); table.Rows.Add(new[] { "1", "9999999", "[e-mail]" }); table.Rows.Add(new[] { "2", "1234567", "[e-mail]" }); table.Rows.Add(new[] { "3", "7654321", "[e-mail]" }); var query = from row in table.AsEnumerable() select new { userid = (string) row["userid"], phone = (string) row["phone"], email = (string) row["email"] }; JObject o = JObject.FromObject(new { Table = query }); Console.WriteLine(o); } } 

文档： 使用Json.NET的LINQ to JSON

Answer 2

 var oSerializer = new System.Web.Script.Serialization.JavaScriptSerializer(); string sJSON = oSerializer.Serialize(yourList);
