C# Regex. Matches Method
The method matches instances of a pattern and is used to extract value based on a pattern.
Let us see hoe to check for a valid URL.
For that, pass the regex expression in the Matches method.
MatchCollection mc = Regex.Matches(text, expr);
Above, the expr is our expression that we have set to check for valid URL.
"^(http|http(s)?://)?([\w-]+\.)+[\w-]+[.com|.in|.org]+(\[\?%&=]*)?”
The text we have set to check is a URL i.e.
https://demo.com
Let us see the complete code.
Example
using System;
using System.Text.RegularExpressions;
namespace Demo {
class Program {
private static void showMatch(string text, string expr) {
MatchCollection mc = Regex.Matches(text, expr);
foreach (Match m in mc) {
Console.WriteLine(m);
}
}
static void Main(string[] args) {
string str = "https://demo.com";
Console.WriteLine("Matching URL...");
showMatch(str, @"^(http|http(s)?://)?([\w-]+\.)+[\w-]+[.com|.in|.org]+(\[\?%&=]*)?");
Console.ReadKey();
}
}
}Output
Matching URL... https://demo.com
