C# winform checkedListBox得到每个item的tooltip

private void checkedListBox1_MouseMove(object sender, MouseEventArgs e)

{

int index = this.checkedListBox1.IndexFromPoint(e.X, e.Y);

if (index != -1)

{ string text = this.checkedListBox1.Items[index].ToString();

this.toolTip1.SetToolTip(this.checkedListBox1, text);

}

}

 

 

哈哈 之前没有关注过IndexFromPoint 此类方法 真的很好用
