Question

c# 钩子有问题

if (hKeyboardHook == 0)
{
// 创建HookProc实例
KeyboardHookProcedure = new HookProc(KeyboardHookProc);
//定义全局钩子
hKeyboardHook = SetWindowsHookEx(13, KeyboardHookProcedure, Marshal.GetHINSTANCE(Assembly.GetExecutingAssembly().GetModules()[0]), 0);
if (hKeyboardHook == 0)
{
HookStop();
throw new Exception("SetWindowsHookEx failed.");
}
；
if (hKeyboardHook != 0)
{
retKeyboard = UnhookWindowsHookEx(hKeyboardHook);
hKeyboardHook = 0;
}

帮忙修改

Answer 1

不懂C#，不过楼下说的似乎是正确的。

Answer 2

SetWindowsHookEx是winapi，C#要DllImport才能用
[DllImport("user32.dll")]
public static extern int SetWindowsHookEx(int, Delegate, IntPtr, int);
[DllImport("user32.dll")]
UnhookWindowsHookEx(int);
