将项添加到选中的列表框 [英] Adding an item to a Checked List Box
问题描述
您好,
我正在尝试将项目添加到选中的列表框中,例如:
clbList.Items.add( 你好,真的)
我收到错误:
抛出运行时异常:System.ArgumentOutOfRangeException - 指定的
参数超出了有效值的范围。参数名称:'' - 1''不是
索引的有效值。
这不是很有意义吗?有什么想法会发生这种情况吗?
问候

Hello,
I am trying to add an item to a checked list box, like:
clbList.Items.add("Hello",true)
I get an error back:
Run-time exception thrown: System.ArgumentOutOfRangeException - Specified
argument was out of the range of valid values. Parameter name: ''-1'' is not a
valid value for index.
This doesn''t make a lot of sense? Any ideas why this happens?

我无法重现。你确定这一行会抛出
异常吗?您使用的是哪个版本的.NET?

I am not able to repro that. Are you sure this line throws the
exception? Which version of .NET do you use?
