如何按一个键，使用C＃释放呢？ [英] How to push a key and release it using C#?

问题描述

我写它可以捕获来自外部设备的信号，并发送键击到另一个应用程序C＃程序。我使用的SendKeys，它工作正常。

I am writing a C# program which captures signals from a external device, and sends keystrokes to another application. I am using SendKeys and it works fine.

做的SendKeyspreSS按住并立即释放它的关键。我想使它推键，随意将其释放。

SendKeys does "press" a key by holding and releasing it immediately. I would like to make it push key and release it at will.

我的问题是：一定的时间后，信号有没有办法来发送推的信号一键，然后释放

My question is : "is there a way to send a "push" signal to a key, then a "release" signal after a certain amount of time ?"

我不知道的SendKeys是能够做到这一点。任何线索？

I am not sure SendKeys is able to do this. Any clue ?

推荐答案

我不认为这是可能的，从.NET直接
的http：这里描述，您可以尝试用p使用keybd_event本地呼叫/调用该函数//的PInvoke。净/ Default.aspx的/ user32.keybd_event

I don't think it's possible from .NET directly You could try using keybd_event native call by p/invoking the function as described here: http://pinvoke.net/default.aspx/user32.keybd_event

在MSDN的keybd_event是在这里：的http：// msdn.microsoft.com/en-us/library/ms646304(VS.85).aspx
