由于winform TextBoxes不公开Paint事件，您需要在WPF中执行它并使用ElementHost here is a WPF Shaped Textbox example。

以下是塑造Panel的示例：

Private Sub Panel1_Paint(sender As Object, e As System.Windows.Forms.PaintEventArgs) Handles Panel1.Paint

    Dim panelPath As New System.Drawing.Drawing2D.GraphicsPath

    ' Set a new rectangle to the same size as the button's  
    ' ClientRectangle property. 
    Dim newRectangle As Rectangle = New Rectangle(0, 0, Panel1.Width, Panel1.Height)


    ' Decrease the size of the rectangle.
    newRectangle.Inflate(-10, -10)

    ' Draw the button's border. 
    e.Graphics.DrawEllipse(System.Drawing.Pens.Black, newRectangle)

    'Increase the size of the rectangle to include the border.
    newRectangle.Inflate(1, 1)

    ' Create a circle within the new rectangle.
    panelPath.AddEllipse(newRectangle)
    e.Graphics.DrawPath(Pens.Black, panelPath)
    ' Set the button's Region property to the newly created  
    ' circle region.
    Panel1.Region = New System.Drawing.Region(panelPath)


End Sub
