Web Forms :: Find A Substring (email) In A Large Text Using Regex?

I want to find a substring (email) in a large text using Regex.

just want to return the first valid email that is found from the input text:

example:

string inputString = "Our email is myname@ourcompany.com.

desired output: myname@ourcompany.com

this is the Regex pattern i've used: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$

- is this pattern correct?

Code:

private static void DumpHRefs(string inputString)
{
Match m;
string HRefPattern = @"^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$";
m = Regex.Match(inputString, HRefPattern,
RegexOptions.IgnoreCase | RegexOptions.Compiled);
while (m.Success)
{
Console.WriteLine("Found email " + m.Groups[1] + " at ".......
