c#利用API读取微信数据_c#获得微信数据

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);
