C# How to Validate a Mobile Phone Number (Simple)
Greetings, today I will be teaching you how to validate a UK Mobile Phone number using C#. This method can be applied to non-UK phone numbers. We will check if the length is 11 digits, that all characters are digits, the first number is 0 and the second number is 7. If all are true tell the user it is valid and if at least one condition isn't true then tell the user it is invalid.
This video is a remake of an older C# video covering how to validate a mobile phone number. For some daft reason, I decided to make the font really small.
