C#获取有关当前活动窗口的信息

Question

我有一个应用程序,我想在后台运行.我想获取可执行文件名,例如IExplorer.exe.我玩过以下代码:

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

[DllImport("user32.dll")]
private static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int count);

public static void Main()
{
    int chars = 256;
    StringBuilder buff = new StringBuilder(chars);
    while (true)
    {
        // Obtain the handle of the active window.
        IntPtr handle = GetForegroundWindow();

        // Update the controls.
        if (GetWindowText(handle, buff, chars) > 0)
        {
            Console.WriteLine(buff.ToString());
            Console.WriteLine(handle.ToString());
        }
        Thread.Sleep(1000);
    }
}

这只能得到Window标题和句柄ID.我想获得可执行文件名称(也许还有更多信息).

我如何实现这一目标？

我想你想要" GetWindowModuleFileName()"而不是GetWindowText你传入了hwnd,所以你仍然需要调用GetForegroundWindow()
