c# - SendMessage，尝试发送F4(SendMessage, Trying to send F4)

Question

My SendMessage signature:

(我的SendMessage签名：)

[DllImport("user32.dll")]
public static extern int SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam);

To get the window handle, I find the MainWindowHandle from the process I want to send messages to:

(为了获取窗口句柄，我从要将消息发送到的进程中找到MainWindowHandle：)

whandle = MemClass.Process.MainWindowHandle;

Here I'm trying to SendMessage to that process window: (0x73 = F4 key)

(在这里，我尝试将SendMessage发送到该进程窗口：（0x73 = F4键）)

SendMessage(whandle, 0x73, 0, 0);

And It's obviously giving error, because I'm sending last 2 params as int instead of IntPtr:

(而且这显然是错误的，因为我将最后两个参数作为int而不是IntPtr发送：)

IntPtr wParam, IntPtr lParam

Tested with this call:

(通过此调用进行了测试：)

SendMessage(whandle, 0x73, IntPtr.Zero, IntPtr.Zero);

0 errors but it's not sending F4 to the window

(0个错误，但未将F4发送到窗口)

How do I call this function correctly?

(如何正确调用此函数？)

I want to send F4 to a process window.

(我想将F4发送到过程窗口。)
