推荐答案

您必须记住C#区分大小写.

如果ListBox的名称是由Visual Studio编辑器分配的，则几乎可以肯定listBox1带有小写的"l".

试试:

You have to remember that C# is case sensitive.

If the name of the ListBox was assigned by the Visual Studio Editor, then it is almost certainly listBox1 with a lower case ''l''.

try:

int cds = listView1.SelectedItems.Count - 1;
