有没有办法在.NET应用程序中打开浏览器中的html文件？

private void button1_Click(object sender, EventArgs e)
{
    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        webBrowser1.Navigate(openFileDialog1.FileName);
    }
}

private void button1_Click(object sender, EventArgs e)
{
    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        Process.Start(openFileDialog1.FileName);
    }
}

private void button1_Click(object sender, EventArgs e)
{
    string url = "http://example.com/file.html";
    WebClient webClient = new WebClient();
    string html = webClient.DownloadString(url);
    webBrowser1.DocumentText = html;
}
