vb.net中怎么给label设置下划线

当鼠标移动过来时显示下划线
鼠标移走时去掉下划线

Answer 1

将Label1 改成相应的 label 控件名称。

'鼠标经过时，显示下划线
Private Sub Label1_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.MouseEnter
Dim LabelFont As Font = New Font(Label1.Font.Name, Label1.Font.Size, FontStyle.Underline)
Label1.Font.Dispose()
Label1.Font = LabelFont
End Sub

'鼠标离开时，去除下划线
Private Sub Label1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label1.MouseLeave
Dim LabelFont As Font = New Font(Label1.Font.Name, Label1.Font.Size, FontStyle.Regular)
Label1.Font.Dispose()
Label1.Font = LabelFont
End Sub
