//HTDbHelper.ExecuteNonQuery(sql);
//int Farm_Id = Convert.ToInt32(Repository.DataContext.ExecuteScalar(CommandType.Text, sql));

int task_id=Convert.ToInt32(HTDbHelper.ExecuteScalar(sql));

 ExecuteScalar返回首行首列值

string Farm_Idsql = "SELECT Farm_ID FROM Base_Farm WHERE Farm_Name='" + farmname + "'";
int Farm_Id = Convert.ToInt32(Repository.DataContext.ExecuteScalar(CommandType.Text, Farm_Idsql));
