What Mitch Wheat said is generally regarded as the correct answer, and what I have done in the past. However, if you want to have a visual control that you can drag on to a form, add the Microsoft.VisualBasic.PowerPack to your visual studio toolbox. To do that right-click on toolbox select "Choose Items...". Locate "Line Shape" on the .Net Framework Components tab.
Mitch Wheat所说的一般被认为是正确的答案，以及我过去所做的。但是，如果您想要一个可以拖到窗体上的可视控件，请将 Microsoft.VisualBasic.PowerPack 添加到您的 Visual Studio 工具箱。为此，请右键单击工具箱选择“选择项目...”。在 .Net Framework 组件选项卡上找到“线条形状”。

One way at design time is to use a Label control and set it's height, or width to 1 (2px and 3D border gives a nice chiseled effect). Or else you can manually draw using GDI:
设计时的一种方法是使用 Label 控件并将其高度或宽度设置为 1（2px 和 3D 边框提供了很好的轮廓分明的效果）。或者你可以使用 GDI 手动绘制：
Dim myPen As New System.Drawing.Pen(System.Drawing.Color.Red)
Dim formGraphics as System.Drawing.Graphics
formGraphics = Me.CreateGraphics()
formGraphics.DrawLine(myPen, 0, 0, 200, 200)
myPen.Dispose()
formGraphics.Dispose()

Private Sub Form1_Paint(sender As Object, e As PaintEventArgs) Handles Me.Paint
e.Graphics.DrawLine(Pens.Black, New Point(0, Me.Height - 1), New Point(Me.Width, Me.Height - 1))
End Sub
This draws a line on the bottom of the control every time it is painted.
每次绘制时，都会在控件底部绘制一条线。
