现在微信电脑版运用比较普遍，平时很想向QQ那样抓取聊天内容，或者作一个自应答系统，在这里写出对微信好友昵称的抓取。希望对大家起到抛砖引玉的作用。
部分源码：

 foreach (Process process in processes)
            {
                if (process.ProcessName == "WeChat")
                {
                    WxProcess = process;
                    this.textBox1.AppendText("微信已找到！" + Environment.NewLine);
                    this.textBox1.AppendText("微信句柄:\t" + "0x" + ((int)(process.Handle)).ToString("X8") + Environment.NewLine);
                    foreach (ProcessModule processModule in process.Modules)
                    {
                        if (processModule.ModuleName == "WeChatWin.dll")
                        {
                            WeChatWinBaseAddress = processModule.BaseAddress;
                            this.textBox1.AppendText("微信基址:\t" + "0x" + ((int)(processModule.BaseAddress)).ToString("X8") + Environment.NewLine);

                            WeChatVersion = processModule.FileVersionInfo.FileVersion;
                            this.textBox1.AppendText("微信版本:\t" + processModule.FileVersionInfo.FileVersion + Environment.NewLine);

            }

                return;
            }

            //微信号
            int WxNameAddress = (int)WeChatWinBaseAddress + 0x1131B90;

            string str1=GetString(WxProcess.Handle, (IntPtr)WxNameAddress);
            byte[] buffer = Encoding.GetEncoding("GB2312").GetBytes(str1);
            string newString = Encoding.UTF8.GetString(buffer); 
            this.textBox1.AppendText("微信号:\t" + newString + Environment.NewLine);

            //微信昵称
            int WxNickNameAddress = (int)WeChatWinBaseAddress + 0x1131C64;
            this.textBox1.AppendText("微信昵称地址:\t" + "0x" + ((int)(WxNickNameAddress)).ToString("X8") + Environment.NewLine);

            this.textBox1.AppendText("微信昵称:\t" + newString1 + Environment.NewLine);
       }

         String GetString(IntPtr hProcess, IntPtr lpBaseAddress, int nSize = 100)
        {
            byte[] data = new byte[nSize];
            if (ReadProcessMemory(hProcess, lpBaseAddress, data, nSize, 0) == 0)
            {
                //读取内存失败！
                return "";
            }
            String result = "";
            String TempString = Encoding.ASCII.GetString(data);
            // \0
