REGEX - Check always start with "/"

In ASP.NET Validator, I want to validate a string like this - "/script/www/test/123.45" Basically, ensure that the string should always start with "/" followed by anything. If it does not start with "/" then its an error condition.

The answers before me are great, just adding yet another extremely simple one:

if (path[0] == '/')

Using a regular expression for this would be like using power tools instead of cutlery when dining.

bool isValid(string sInputString)
{
  Regex rex = new Regex(@"^/");
  return rex.IsMatch(sInputString);
}

if( !path.StartsWith("/") ) throw...

?

Regex seems like overkill.
