public static string Dtb2Json(DataTable dtb)
{
JavaScriptSerializer jss = new JavaScriptSerializer();
System.Collections.ArrayList dic = new System.Collections.ArrayList();
foreach (DataRow dr in dtb.Rows)
{
System.Collections.Generic.Dictionary<string, object> drow = new System.Collections.Generic.Dictionary<string, object>();
foreach (DataColumn dc in dtb.Columns)
{
drow.Add(dc.ColumnName, dr[dc.ColumnName]);
}
dic.Add(drow);

//序列化
return jss.Serialize(dic);
