how to check if a url has a substring

Question

I am trying to make something that will enable all controls if a SubString in a WebBrowser matches a SubString in a TextBox and if it does it will enable all controls, but I can't seem to get it to work.

This is my current code:

string str = "www.google.com";

int pos = str.IndexOf(".") + 1;
int pos2 = str.LastIndexOf(".") - 4;
string str2 = str.Substring(pos, pos2);

if (webBrowser1.Url.AbsoluteUri.Substring(pos, pos2) == textBox1.Text.Substring(pos, pos2))
{
    foreach (Control c in Controls)
    {
        c.Enabled = true;
    }
}

Any and all help will be appreciated.

Answer 1

The Uri class is a wonderful thing.

Uri google = new Uri("http://www.google.com/");
if (webBrowser.Url.Host == google.Host){
}

Or even simply:

if (webBrower.Url.Host.ToLower().Contains("google")) {
}

Answer 2

Just use string.contains

if(textBox1.Text.ToLower().Contains(str.ToLower()))
...
