如何使用c#在and浏览器中输入数据并按下按钮？

private void Form1_Load(object sender, EventArgs e)
{
    webBrowser1.Navigate("https://www.google.com");
}

HtmlElement inputBox = webBrowser1.Document.GetElementById("inputBox");
inputBox.SetAttribute("value", "输入的数据");

HtmlElement submitButton = webBrowser1.Document.GetElementById("submitButton");
submitButton.InvokeMember("click");

using System;
using System.Windows.Forms;

namespace WebBrowserExample
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            webBrowser1.Navigate("https://www.google.com");
        }

        private void btnSubmit_Click(object sender, EventArgs e)
        {
            HtmlElement inputBox = webBrowser1.Document.GetElementById("inputBox");
            inputBox.SetAttribute("value", "输入的数据");

            HtmlElement submitButton = webBrowser1.Document.GetElementById("submitButton");
            submitButton.InvokeMember("click");
        }
    }
}
