Well, this is the web method I'm using to convert my DataTable into JSON string:
public static string GetJSONString(DataTable Dt)
{
string[] StrDc = new string[Dt.Columns.Count];
string HeadStr = string.Empty;
for (int i = 0; i < Dt.Columns.Count; i++)
{
StrDc[i] = Dt.Columns[i].Caption;
HeadStr += "\"" + StrDc[i] + "\" : \"" + StrDc[i] + i.ToString() + "¾" + "\",";
}
HeadStr = HeadStr.Substring(0, HeadStr.Length - 1);
StringBuilder Sb = new StringBuilder();
Sb.Append("{\"" + Dt.TableName + "\" : [");
for (int i = 0; i < Dt.Rows.Count; i++)
{
string TempStr = HeadStr;
Sb.Append("{");
for (int j = 0; j < Dt.Columns.Count; j++)
{
sw ...
