Bring .NET winform to front (focus) on Windows 8

Question

I have a .NET 4.5 C# winforms app that, when a barcode scan is detected, is supposed to come to the foreground (in front of all other apps/windows). I'm using this code to accomplish it:

if (this.WindowState == FormWindowState.Minimized)
{
    this.WindowState = FormWindowState.Normal;
}
this.Activate();

This works perfectly on Windows 7 but doesn't work on Windows 8. If my app is only minimized (and was the most recent app to have focus), it does work, with this line:

this.WindowState = FormWindowState.Normal;

But if any other window/app is IN FRONT OF my app when the barcode scan occurs, this.Activate() clearly doesn't work on Windows 8.

What is the solution?

您需要设置表单的TopMost属性。

this.TopMost = true;
