表格截图
我想获取表单下的屏幕截图，所以我先隐藏它并在捕获后显示。但在我的 Windows 7 上，表单并未完全最小化，因此我在屏幕截图中获取了表单。我如何确保我的表单完全最小化？
WindowState = FormWindowState.Minimized;
Bitmap screenshot = ScreenUtils.ScreenShot();
background = screenshot;
WindowState = FormWindowState.Normal;
PS Hide() 和 Show() 也有同样的问题。
I want to get screenshot of screen under my form, so I hide it first and show after capturing. But on my Windows 7 form is not completely minimize, so I get form on screenshot. How can I be sure that my form is competely minimize?
WindowState = FormWindowState.Minimized;
Bitmap screenshot = ScreenUtils.ScreenShot();
background = screenshot;
WindowState = FormWindowState.Normal;
P.S. Hide() and Show() have the same problem.

您可以将表单不透明度设置为 0，调用刷新以确保绘画完成，捕获，将不透明度重置为 1，然后再次调用刷新
you could set your forms opacity to 0, call refresh to make sure the painting is done, capture, reset opacity to 1 and call refresh again
您是否尝试在进行屏幕截图之前先睡一觉？
Did you try to build in a sleep before making a screenshot?
