如何通过编码点击按钮？

Question

我的程序中有两个按钮,我希望当我按下第一个按钮时,第二个按钮被自动点击(在第一个按钮的事件处理程序中,我想通过编码按下第二个按钮).

private void button1_Click(object sender, EventArgs e)
    {

        passWord = pwd.Text;
        user = uName.Text;


        loginbackend obj = new loginbackend();
        bool isValid = obj.IsValidateCredentials(user, passWord, domain);
        if (isValid)
        {
            loginbackend login = new loginbackend();
            passWord = pwd.Text;

            login.SaveUserPass(passWord);
            HtmlDocument webDoc = this.webBrowser1.Document;
            HtmlElement username = webDoc.GetElementById("__login_name");
            HtmlElement password = webDoc.GetElementById("__login_password");

            username.SetAttribute("value", user);
            password.SetAttribute("value", passWord);

            HtmlElementCollection inputTags = webDoc.GetElementsByTagName("input");

            foreach (HtmlElement hElement in inputTags)
            {
                string typeTag = hElement.GetAttribute("type");
                string typeAttri = hElement.GetAttribute("value");

                if (typeTag.Equals("submit") && typeAttri.Equals("Login"))
                {
                    hElement.InvokeMember("click");

                    break;
                }
            }
            button3_Click(sender, e);
            label1.Visible = false ;
            label3.Visible = false;
            uName.Visible = false;
            pwd.Visible = false;
            button1.Visible = false;
            button2.Visible = true;
    }
         else 
        {
            MessageBox.Show("Invalid Username or Password");
        }

    }
private void button3_Click(object sender, EventArgs e)
    {
        HtmlDocument webDoc1 = this.webBrowser1.Document;
        HtmlElementCollection aTags = webDoc1.GetElementsByTagName("a");

        foreach (HtmlElement link in aTags)
        {
            if (link.InnerText.Equals("Show Assigned"))
            {
                link.InvokeMember("click");
                break;
            }
        }
    }

我认为你所描述的是你想要在单击按钮B时调用方法,但是当单击按钮A时也调用该方法.

protected void ButtonA_Click(...)
{
    DoWork();
}

protected void ButtonB_Click(...)
{
    // do some extra work here
    DoWork();
}

private void DoWork()
{
    // do the common work here
}

根据您在事件处理程序中的实现,您也可以从第一个按钮中调用第二个按钮的事件处理程序,但上面的方法是"正确"的方法.
