问题描述

我有我改变背景颜色为 Col​​or.Yellow 单击时它的winform的按钮。当它再次点击我想把它恢复到原来的默认外观。

I have a button on a winform which I change the background color to Color.Yellow when it's clicked. When it's clicked again I want to restore it to the original default appearance.

默认背景色为 SystemColor.Control 。

当点击按钮时，我第一次改变的唯一的事情是

When the button is clicked the first time the only thing I change is the

btn.Text = "ABC";
btn.BackColor = Color.Yellow;

当它再次点击我

btn.BackColor = SystemColors.Control

新的背景不具有相同的阴影，因为它的点击之前本来。按钮原本有一个背景，这不是纯色但2略有不同的灰色色调。最终的颜色最终被灰色坚实的阴影。

The new background does not have the same shading as it originally did before any clicks. The button originally had a background that was not a solid color but was 2 slightly different shades of grey. The final color ends up being a solid shade of grey.
