Look into the BlockInputWin32 function

Expanding on Josh's (correct) answer. Here's the PInvoke signature for that method.
扩展乔希的（正确）答案。这是该方法的 PInvoke 签名。
public partial class NativeMethods {
/// Return Type: BOOL->int
///fBlockIt: BOOL->int
[System.Runtime.InteropServices.DllImportAttribute("user32.dll", EntryPoint="BlockInput")]
[return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)]
public static extern bool BlockInput([System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)] bool fBlockIt) ;
}
public static void BlockInput(TimeSpan span) {
try {
NativeMethods.BlockInput(true);
Thread.Sleep(span);
} finally {
NativeMethods.BlockInput(false);
}
}

Added some code to demonstrate how to block for an interval

Have a look at this article Processing Global Mouse and Keyboard Hooks in C#. The guy who wrote this article have done alot of research around the problem.
看看这篇文章用 C# 处理全局鼠标和键盘挂钩。写这篇文章的人围绕这个问题做了很多研究。
Maybe there is somthing in it you can use.
也许里面有你可以使用的东西。
