How to get the url of a WebBrowser control

        if (webBrowser1.Url.AbsoluteUri == "www.google.com")
        {
            label9.Text = webBrowser1.Url.AbsoluteUri;
        }

This is my current code. When I click the button to run, I get an error.

An object reference is not set on an object instance.

And I don't know why he does it or how to fix it. Any help would be great.

It also needs to run on a timer so that it can be checked.

maybe yours webBrowser1.Url

- null

try below to get url



    string url = "";
    if (webBrowser1.Url != null)
    {
        url = webBrowser1.Url.AbsoluteUri;
    }
    if (url == "www.google.com")
    {
        label9.Text = url;

The property Url

will remain null

until the control is rendered, so use this:

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) {
     if (webBrowser1.Url.ToString() == "www.google.com") {
          label9.Text = webBrowser1.Url.ToString();
     }
}


And in your button Click

event add:

webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);

Well, you didn't provide the url (the page doesn't load in the web browser). You can try this:

webBrowser1.Url = new Uri ("http://www.google.com", UriKind.Absolute);

And get the url like this: webBrowser1.Url.ToString ();

Wait for the page to load and then click the button.

I thought id was a comment on this, I literally took your

"webBrowser1.Url.AbsoluteUri;"

and in my case i am using combotextbox so double click your browser form and it will take you to the even handler, i will just put

"combobox1.text= webBrowser1.Url.AbsoluteUri;"

and now it works for me. You got me in time, but all you need to check is check on combobox1.text or whatever you use for your url.

    string url = browser1.Address;
