Question

I have the following code which works fine but i need to replace the site address with a variable…

string url = HttpContext.Current.Request.Url.AbsoluteUri;  // Get the URL

bool match = Regex.IsMatch(url, @"(^|\s)http://www.mywebsite.co.uk/index.aspx(\s|$)");

I have tried the following but it doesn’t work, any ideas???

string url = HttpContext.Current.Request.Url.AbsoluteUri;  // Get the URL
string myurl = "http://www.mywebsite.co.uk/index.aspx";

bool match = Regex.IsMatch(url, @"(^|\s)"+myurl+"(\s|$)");

Answer 1

You are missing a @:

bool match = Regex.IsMatch(url, @"(^|\s)" + myurl + @"(\s|$)");

The reason that you need the extra @ is because the @ applies only to the string literal immediately following it. It does not apply to the entire rest of the line.

You should also consider escaping your URL:

bool match = Regex.IsMatch(url, @"(^|\s)" + Regex.Escape(myurl) + @"(\s|$)");
