public void createsqltable(DataTable dt,string tablename)
        {

            string table = "";
            table += "IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + tablename + "]') AND type in (N'U'))";
            table += "BEGIN ";
            table += "create table " + tablename + "";
            table += "(";
            for (int i = 0; i < dt.Columns.Count; i++)
            {
                if (i != dt.Columns.Count-1)
                    table += dt.Columns[i].ColumnName + " " + "varchar(max)" + ",";
                else

            }
            table += ") ";
            table += "END";
            InsertQuery(table,strconnection);
            CopyData(strconnection, dt, tablename);
        }
