Graphics 问题，在线等~~
一个简单的问题
我现在用g.DrawLine()的方法画一条线
但如果在一条线的中间有个控件的话则控件这段线会被遮盖掉，如何可以使控件这段线不被遮盖呢？

------解决方案--------------------
API可以。

public class test

}
public test()
{
m_nX = 8;
y = 72;
}
}
private void button1_Click(object sender, EventArgs e)
{
int x = test.y;
test d = new test();
int z = test.y;
}

public static extern IntPtr GetWindowDC(IntPtr hwnd);
[DllImport( "user32.dll ", EntryPoint = "ReleaseDC ")]

}

private void Form1_Paint(object sender, PaintEventArgs e)
{
IntPtr hDC = GetWindowDC(this.Handle);
using (Graphics g = Graphics.FromHdc(hDC))
{
g.DrawLine(Pens.Black, 0, 0, 150, 150);
}
ReleaseDC(this.Handle, hDC);
}
}
