我将我的datatable转换为c#通用列表。
DataTable dt = mydata(); List<DataRow> list = dt.AsEnumerable().ToList();
现在我如何使用json.net将此列表转换为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" : "test@test.com","role" : "Admin","empId" : "","reportingto" : ""},{"userid" : "2","name" : "chendurpandian","designation" :
"softwaredeveloper","phone" : "9566643707","email" : "chendur.pandia@gmail.com","role" : "Super User","empId" : "1","reportingto" : "xavyTechnologies"},{"userid" : "3","name" : "sabarinathan","designation" : "marketer","phone" :
"66666666666","email" : "bala3569@gmail.com","role" : "User","empId" : "2","reportingto" : "chendurpandian"}]}
这里有一个例子：
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","test@test.com" });
table.Rows.Add(new[] { "2","1234567","foo@test.com" });
table.Rows.Add(new[] { "3","7654321","bar@test.com" });
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);
}
}
