[Help] - Check if a webpage contains some text then do something (C#)

[KynloStephen66515]

Actually going to pull my hair out if I can't work this out lol

Trying to work out how the hell to check if a webpage contains a certain string of text, and if it does, then do something (I know how to get it to do something afterwards...just can't work out how to CHECK)

In non-code, this would be:

if webPage.ContainsString("No Messages Found") {  //Do Something } else { //Do Something Different }

Bit vague on this I know, I suck at explaining these things

You can use a webbrowser control to fetch the page, then check its content with a regex.

I was already using a webBrowser control and was looking into using the HTML Agility Pack I got off NuGet to do this, but it is seeming like a pain in the ass...Also..I suck BADLY with Regex lol

You need to decide on which control you will use. I'll use the stock control here.

Code: (csharp)

        private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            if (webBrowser1.DocumentText.Contains("No Messages Found")) {
                this.Text = "No Messsaged Found found";
            }
        }

That is all you need.

There's a fix for that, reported here, in our DC forum

I couldn't actually get that to even DO anything lol (Although, it does compile...so might be something I did(n't) do.)

One way to not even use the web browser control should be as simple as this...

Code: (csharp)

WebClient myWebClient = new WebClient();
string siteSource = myWebClient.DownloadString("PLEASECHANGETOYOURURL");

if (siteSource.Contains("YOURTEXT"))
{
// Your string found code here.
}
else
{
// Your string not found code here.
}

Here's the project:

You can run the debug or compile it yourself. It's done in VS2010.

The WebClient method is actually better, but the way I have that there is a bit more visual with a control, etc. Also, you can actually surf with it.
