用C#能在QQ窗体里发送消息吗？

 AutomationElement aeDeskTop = AutomationElement.RootElement;



                // 不设定查找条件，列出所有窗体

                this.textBox1.AppendText("\r\n");

                AutomationElementCollection elementCollection = aeDeskTop.FindAll(TreeScope.Children, Condition.TrueCondition);

                foreach (AutomationElement frm in elementCollection)

                {

                    this.textBox1.AppendText(string.Format("窗体名称:{0}\r\n", frm.Current.Name));

                    if (frm.Current.Name == "豆干") //这里是打开的QQ窗体的名称

                    {

                        elementCollection = frm.FindAll(TreeScope.Subtree,

                            Condition.TrueCondition);

                        foreach (AutomationElement control in elementCollection)

                        {

                            this.textBox1.AppendText(string.Format("控件id:{0}\r\n", control.Current.AutomationId));

                        }

                    }

                }

//从网上找到的输入文本内容

System.Windows.Forms.SendKeys.SendWait(textBox2.Text);



//从网上找到的点击发送消息按钮

 InvokePattern ipClickButton1 = (InvokePattern)aeAllEdit1[t].GetCurrentPattern(InvokePattern.Pattern);

                                                    ipClickButton1.Invoke();

//这两步都无法实现
