推荐答案

您可以所有进程并尝试使用 System.Diagnostics.Process.MainWindowHandle获取每个进程的主窗口句柄：

处理.GetProcesses方法（System.Diagnostics），

Process.MainWindowHandle Property（System.Diagnostics）。



注意： MainWindowHandle 可能会抛出异常N;所以你必须抓住它并忽略这种情况。



对于每个句柄，你可以 GetForegroundWindow 的方式你在解决方案3中写道（但这不是解决方案）。

-SA

You can get all processes and try to get a main window handle of each one using System.Diagnostics.Process.MainWindowHandle:
Process.GetProcesses Method (System.Diagnostics),
Process.MainWindowHandle Property (System.Diagnostics).

Pay attention: MainWindowHandle may throw and exception; so you have to catch it and just ignore this case.

For each handle, you can GetForegroundWindow the way you wrote in Solution 3 (but this is not a solution).

—SA

unsafe
{
  var notepadProcs = Process.GetProcessesByName("notepad");
  if (notepadProcs.Length > 0)
  {
    // Main window handle in IntPtr
    var mainWindowHandle = notepadProcs[0].MainWindowHandle;

    // Main window handle in unmanaged pointer
    var mainWindowPtr = (byte*) mainWindowHandle.ToPointer();
  }
}

[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();

...
IntPtr activeWindow = GetForegroundWindow();
byte *mainWindowPtr = (byte*) activeWindow.ToPointer();
...
