Can any body tell me logic of key logger?

推荐答案

为什么?

好的，就是这样: http://en.wikipedia.org/wiki/Key_logger [ ^ ].

您可能是指软件密钥记录器.根据Microsoft的说法，用C#创建是不可能的.它需要一个Windows Hook才能注册.请参阅 http://msdn.microsoft.com/en-us/library /ms632589%28v=vs.85%29.aspx [ ^ ].问题是系统全局挂钩的注册和使用.它必须在非托管DLL中实现，您可以使用该DLL与.NET软件进行通信.

Why?

OK, this is what it is: http://en.wikipedia.org/wiki/Key_logger[^].

You probably mean software key logger. According to Microsoft, it impossible to create with C#. It needs a Windows Hook to be registered. See http://msdn.microsoft.com/en-us/library/ms632589%28v=vs.85%29.aspx[^]. The problem is registration and using of a system-global hook. It must be implemented in an unmanaged DLL which you can use to communicate with your .NET software.

See the following CodeProject articles helping to implement Global System Hook in C# with the help of C++ unmanaged DLL:

Global System Hooks in .NET[^],
Processing Global Mouse and Keyboard Hooks in C#[^].

逻辑很简单.键盘上键入的每个键都由程序捕获.
可以使用键盘挂钩来实现.

The logic is simple enoough. Every key typed on the keyboard is captured by a program.
This can be achieved using a keyboard hook.
