问题说明
假设的notepad.exe是开放和它的窗口处于非活动状态。我会写一个应用程序来激活它。如何使？

更新：窗口标题是不确定的。所以，我不喜欢它基于窗口的标题使用的FindWindow。
Update: The window title is undefined. So, I don't like to use to FindWindow which based on window's title.

您需要的P / Invoke SetForegroundWindow（）。 Process.MainWindowHandle可以给你你需要的手柄。例如：
You'll need to P/invoke SetForegroundWindow(). Process.MainWindowHandle can give you the handle you'll need. For example:
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
class Program {
static void Main(string[] args) {
var prc = Process.GetProcessesByName("notepad");
if (prc.Length > 0) {
SetForegroundWindow(prc[0].MainWindowHandle);
}
}
[DllImport("user32.dll")]
private static extern bool SetForegroundWindow(IntPtr hWnd);
}
请注意，如果你有记事本中运行多个副本的模糊性。
Note the ambiguity if you've got more than one copy of Notepad running.
