C# program to check for URL in a String

Use the StartWith() method in C# to check for URL in a String.

Let us say our input string is ?

string input = "https://example.com/new.html";

Now we need to check for www or non-www link. For this, use the if statement in C# ?

if (input.StartsWith("https://www.example.com") || input.StartsWith("https://example.com")) {
}

Example

You can try to run the following code to check for URL in a string.

using System;
class Demo {
    static void Main() {
        string input = "https://example.com/new.html";
        // See if input matches one of these starts.
        if (input.StartsWith("https://www.example.com") || input.StartsWith("https://example.com")) {
            Console.WriteLine(true);
        }
    }
}

Output

True
