推荐答案

对其进行迭代并构建一个仅包含已检查内容的int列表.假设已经没有财产了，这会让我感到惊讶.

我想您住的地方没有Google.我知道了，所以我找到了:

http://msdn.microsoft.com/en-us/library/system.windows.forms.checkedlistbox.checkedindexcollection.aspx [ ^ ]

但是，您肯定会获得完整的Visual Studio吗?它具有智能.打 .然后您会在该对象上获得方法列表.当然，"CheckedItems"是自记录文件吗?

Iterate over them and build a list of ints that contains only the ones that are checked. Assuming there''s no property for that already, which would surprise me.

I guess you don''t have google where you live. I do, so I was able to find this:

http://msdn.microsoft.com/en-us/library/system.windows.forms.checkedlistbox.checkedindexcollection.aspx[^]

However, surely you get the full visual studio ? It has intellisense. Hit . and you get a list of methods on the object. Surely ''CheckedItems'' is self documenting ?

我相信您是在要求以下内容:

I believe you were asking for this:

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
       {
           if (e.NewValue == CheckState.Checked)
           {
               MessageBox.Show(e.Index.ToString());
           }
       }
