The best way is to use the regular expressions, if you dont know how to build a rigular expression then those sites in witches you can find ready to use regular expression like this

site1
or simply by google it Regualr expression + C#

use the IsMatch method of the Regex class

if(Regex.IsMatch(regular expresion, text or expression to check))
{
take action 1
}
else
{
take action 2
}
