如何检测Url是书签格式

Question

帮助

我想在新窗口中打开url，bookmarkformt在当前Webbrowser 中打开的url

我有一个简单的方法来检测书签格式的url

file:///D:/Administrator/Desktop/123.htm#222

包含.htm#或.htm#

这是正确的书签格式url

//书签名称为222

file:///D:/Administrator/Desktop/123.htm#222

//书签名称为##abc

file:///D:/Administrator/Desktop/123.htm###abc

//书签名称为//.HTM##.HTM#abc#.html##//

file:///D:/Administrator/Desktop/123.htm#//.HTM##.htm#abc#.html##//

如何检测Url是否为书签格式？正则表达式可以解决这个问题，我不能写一个正确的正则表达式吗？

这是我的解决方案，但需要检测url是书签格式

string htmFilename = @"D:AdministratorDesktop123.htm";
private void Form1_Load(object sender, EventArgs e)
{
    webBrowser1.StatusTextChanged += new EventHandler(webBrowser1_StatusTextChanged);
    webBrowser1.Navigate(htmFilename);
    navigated = true;
}

private void webBrowser1_StatusTextChanged(object sender, EventArgs e)
{
    textBox1.Text = webBrowser1.StatusText;
}
//webBrowser1  Navigating the first time not open in new window
bool navigated = false;
private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    //first time nagivate 
    if (navigated == true)
    {
        //  url is not bookmark format 
        // open in new window
        if (e.Url.ToString().Contains(".htm#") == false)
        {
            e.Cancel = true;
            //webBrowser1.Navigate(e.Url, true);
            //Process.Start is bettor then webBrowser1.Navigate(e.Url, true);
            //Because when url is directory link such as "file:///C:/"
            //webbrowser will open a blank window and then open the Directory
            
            System.Diagnostics.Process.Start(e.Url.ToString());
        }
    }
    textBox2.Text = e.Url.ToString();
}
