データテーブルをc#ジェネリックリストに変換しています。
DataTable dt = mydata();
List<DataRow> list = dt.AsEnumerable().ToList();
どうすれば、json.netを使用してこのlist
をjsonに変換できますか?なにか提案を。
Json形式のサンプルは次のようになります。
{"Table" : [{"userid" : "1","name" : "xavyTechnologies","designation" : "",
"phone" : "9999999999","email" : "[email protected]","role" : "Admin","empId" : "",
"reportingto" : ""},{"userid" : "2","name" : "chendurpandian","designation" :
"softwaredeveloper","phone" : "9566643707","email" : "[email protected]",
"role" : "Super User","empId" : "1","reportingto" : "xavyTechnologies"},
{"userid" : "3","name" : "sabarinathan","designation" : "marketer","phone" :
"66666666666","email" : "[email protected]","role" : "User",
"empId" : "2","reportingto" : "chendurpandian"}]}
以下はその一例です。
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", "[email protected]" });
table.Rows.Add(new[] { "2", "1234567", "[email protected]" });
table.Rows.Add(new[] { "3", "7654321", "[email protected]" });
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);
}
}

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