嗨Dom，
没有内置的C＃线控制，但是，它是相当直接的 -
前锋：
只需进行用户控制即可覆盖OnPaint：
公共类Foo：UserControl
{
public Foo（）
：base（）
{
}
protected override void OnPaint（PaintEventArgs e）
{
base.OnPaint（e）;
使用（System.Drawing.Pen p = new
System.Drawing。笔（System.Drawing.Color.Red））
{
e.Graphics.DrawLine（p，0,0,200,200）;
}
}
}
干杯，
格雷格

哇。这是很多工作。这就是我最终做的事情。我使用了一个
GroupBox没有标题，高度为5.

VB had a "line" control, just a simple line that let you separate
controls without the wasted space of a Groupbox. Did CSharp drop
this?

DomHi Dom,
There is no built-in C# line control, however, it''s fairly straight-
forward:
Just make a usercontrol and override the OnPaint:
public class Foo : UserControl
{
public Foo()
: base()
{
}
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
using (System.Drawing.Pen p = new
System.Drawing.Pen(System.Drawing.Color.Red))
{
e.Graphics.DrawLine(p, 0, 0, 200, 200);
}
}
}
Cheers,
Greg
