推荐答案

Quote：

ClsClientReg obj = new ClsClientReg（）;

obj.DeleteClient（int32Id）;

ClsClientReg obj = new ClsClientReg();
obj.DeleteClient(int32Id);

如果第一行创建（因为它）看起来是一个空对象，第二行注定要失败。

If the first line creates (as it looks) an empty object, the second line is destined to fail.

Gridview datakeys集合似乎是空的。



设置DataKeyNames属性，然后访问它。

The Gridview datakeys collection seems to be empty.

Set the DataKeyNames property and then access it.
