急需：C#语句如何HOOK API

Question

C#估计是做不了,要做的话用VC++吧!

Answer 1

我感觉既然C#能调用下面API Hook窗口的键盘鼠标消息，应该也能实现搂主需求，不过我没做过
[DllImport("user32.dll")]
private static extern IntPtr SetWindowsHookEx(HookType code, HookProc func, IntPtr hInstance, int threadID);[DllImport("user32.dll")]
private static extern int UnhookWindowsHookEx(IntPtr hhook); [DllImport("user32.dll")]
private static extern int CallNextHookEx(IntPtr hhook, int code, IntPtr wParam, IntPtr lParam);

用于进程注入其他的类似

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

using System.Diagnostics;
