您正在Default.aspx中使用ExecuteNonQuery

You are using ExecuteNonQuery in your Default.aspx

如果没有记录受查询影响，则ExecuteNonQuery返回-1.

ExecuteNonQuery returns -1 if no records affected by your query.

在这里，您已经在存储过程中设置了nocounton.这就是为什么在您的executenonquery中没有记录受影响的值(意味着-1)即将到来.

Here you have set nocounton in your stored procedure. That's why in your executenonquery no records affected value( means -1) is coming.

设置计数，您将获得理想的结果.

Set your count on you will get desired result.
