using System.Runtime.InteropServices;
...
[DllImport("user32.dll")]
private static extern IntPtr SendMessage
(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);
For usage information look at http://msdn.microsoft.com/en-us/library/ms644950%28VS.85%29.aspxGeneraly you must only call this function with good arguments, to know what arguments you need you must look at msdn.
有关使用信息，请查看http://msdn.microsoft.com/en-us/library/ms644950%28VS.85%29.aspx一般而言，您只能使用正确的参数调用此函数，要知道您需要哪些参数，您必须查看在 msdn。

This is a duplicate question to this one: Using SendMessage for Simulating User Mouse Clicks.
这是一个重复的问题：Using SendMessage for Simulating User Mouse Clicks。
The answer there recommends that you investigate WIN32 journal hooks, thus sending WH_JOURNALPLAYBACK.
那里的答案建议您调查 WIN32 日志挂钩，从而发送 WH_JOURNALPLAYBACK。
And another duplicate with what is reported to be a working snippet: Clicking mouse by sending messages
另一个重复的报告是一个工作片段：通过发送消息单击鼠标
This discussion on MSDN indicates that it's not so easy using the raw mouse messages: http://social.msdn.microsoft.com/Forums/hu-HU/vbide/thread/5352d3b8-4f9e-4a0a-8575-fdd592ae45f8.
