推荐答案
很明显，这行
mi_returnmode = ds2.Tables[0].Rows[0]["mi_return_mode"].ToString();
在这两种方法中的一种/两种方法中，都访问没有行的表.
Obviously the line
mi_returnmode = ds2.Tables[0].Rows[0]["mi_return_mode"].ToString();
in either one/both of the methods accesses a table with no rows.
在查找表中的行之前，先检查表中是否存在行.例如:
Check for the existence of rows in the table before looking for values on those rows. For example:
if (ds2.Tables[0].Rows.Count > 0) {
mi_returnmode = ds2.Tables[0].Rows[0]["mi_return_mode"].ToString();
}
