c# - sendmessage API 中的按钮单击

Question

如何在 C# 中模拟 sendmessage API 中的按钮单击？

Answer 1

C 代码:

#include <Windows.h>
//...
SendMessage(hWndButton, BM_CLICK, 0, 0);

C# 代码:

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

...
Button myButton = ...;
const int BM_CLICK = 0x00F5;
SendMessage(myButton.Handle, BM_CLICK, IntPtr.Zero, IntPtr.Zero);

但请注意，在 C# 中，您可以轻松地执行以下操作:

myButton.PerformClick();
