checkListbox的单选

首先要在前面的事件里面添加
this.checkedListBox3.ItemCheck += new System.Windows.Forms.ItemCheckEventHandler(this.checkedListBox3_ItemCheck);
然后在后面cs里面写：

 1       /**//// <summary>
 2       /// checklistbox3单选
 3       /// </summary>
 4       /// <param name="sender"></param>
 5       /// <param name="e"></param>
 6       private void checkedListBox3_ItemCheck(object sender, System.Windows.Forms.ItemCheckEventArgs e)
 7       {
 8           if (checkedListBox3.CheckedItems.Count > 0)
 9           {
10               for (int i = 0; i < checkedListBox3.Items.Count; i++)
11               {
12                   if (i != e.Index)
13                   {
14                       this.checkedListBox3.SetItemCheckState(i, System.Windows.Forms.CheckState.Unchecked);
15                   }
16               }
17
18           }
19       }
