C#中label控件的BackColor如何设置为透明

[zhuzhanghua4213]

在Wince系统中，我用C#编程，里面用到label控件，本来label控件的BackColor值如果不设置的话，label控件可以透明，可以随背景色改变而改变，但是如果我在程序中用代码设置label控件的BackColor值为某种颜色后，再用代码想修改label控件的BackColor值为透明，就再也修改不回来了，有什么办法可以用代码来设置label控件的BackColor值为透明？急求答案！谢谢

补充，在Wince中用Color.Transparent是没有用的。

没人会吗？顶一下，希望有人解答！

drawBounds = labSource.Bounds;



drawBounds.X -= picTarget.Location.X;

drawBounds.Y -= picTarget.Location.Y;



if (labSource.TextAlign == ContentAlignment.TopLeft)
{
grx.DrawString(labSource.Text, labSource.Font, new SolidBrush(labSource.ForeColor), drawBounds);
}


else if (labSource.TextAlign == ContentAlignment.TopCenter)
{
sizeTmp = grx.MeasureString(labSource.Text, labSource.Font);

intleft = picTarget.Width / 2 - Convert.ToInt32(sizeTmp.Width) / 2;

intleft -= picTarget.Location.X;
Rectangle rect = new Rectangle(labSource.Left, labSource.Top, Convert.ToInt32(sizeTmp.Width), Convert.ToInt32(labSource.Height));

grx.DrawString(labSource.Text, labSource.Font, new SolidBrush(labSource.ForeColor), rect);
}

else if (labSource.TextAlign == ContentAlignment.TopRight)
{

sizeTmp = grx.MeasureString(labSource.Text, labSource.Font);

intleft = labSource.Width - Convert.ToInt32(sizeTmp.Width) + labSource.Left;

labSource.Left -= picTarget.Location.X;

Rectangle rect = new Rectangle(labSource.Left, labSource.Top, Convert.ToInt32(sizeTmp.Width), Convert.ToInt32(sizeTmp.Height));

grx.DrawString(labSource.Text, labSource.Font, new SolidBrush(labSource.ForeColor), rect);

}
}

前面加一句：label.parent=??//??代表后面的控件

干嘛不修改属性。如果要知道代码是怎么写的，再查看源码不就好了
我是个菜鸟，只会用笨方法

直接将label控件的backcolor属性设置成Transparent即可
