推荐答案

你好roham_06，

首先，将选择模式"属性设置为多扩展".

Hi roham_06,

First you set Selection mode property to Multi Extended.

for(int nCount=0;nCount < listbox1.SelectedItems.Count;nCount++)
  {
    listbox1.Items.Remove(listbox1.SelectedItems[nCount].ToString());
    nCount--;
  }

在任何事件中进行编码

在删除处理程序"中:

In the ''delete handler'':

Object [] a = new Object[listBox1.SelectedItems.Count];
listBox1.SelectedItems.CopyTo(a, 0);
foreach (Object obj in a)
  listBox1.Items.Remove(obj);

请注意，我也是C#新手:也许有更好的方法来完成任务.

Please note, I''m a C# newbie too: maybe there are better ways to accomplish the task.
