In general, it might be more accurate to say PhoneAttribute.cs determines if a submitted number is "phone number-ish" That's ok, because there is readily available code that performs much more extensive phone number validation. There is no check to determine whether the potential phone number is valid in a specific country.There is no check on the length of the phone number submitted.For example, "1 (800) LOAN-YES" and "1 (800) MICROSOFT" can both be dialed as phone numbers in the United States. Phone numbers sometimes contain alpha characters.
Phone numbers are permitted to be expressed with digits and the characters "-.()" plus an extension marked with "ext.", "ext", or "x".A better understanding of how this class works can be had by examining the source code on GitHub.Ī read-through of the code reveals a number of potential concerns for robust phone number validation: Limitationsīoth these formats are documented as performing validation with a regular expression, but the documentation itself is silent on the regular expression(s) used. Although both approaches will work identically in the vast majority of cases, the derived class format does make your code more complex behind the scenes and provide a path for introducing bugs, so it’s better to use enumeration format unless your requirements call for the derived class. It is not unusual to see and used interchangeably in C# code, and since the first usage is shorter many developers turn to it as a matter of habit.

In the example below, and are validation attributes used to decorate the Title property of the Movie class. NET frameworks provide functionality to abstract data validation into validation attributes which are used to "decorate" the properties of entity classes. This is the standard approach in web applications using the Model View Controller (MVC) libraries. NET frameworks uses class objects to store data.

NET projects and easily leverage this powerful functionality.NET Data ValidationĪ common design pattern in software built with C# and the. This post shows how you can implement libphonenumber-csharp in your. It’s derived from an open source library created by Google. NET frameworks provide for validating phone numbers, the capabilities are limited, particularly with respect to internationalization (“i18n”).įortunately, there is a open source library, libphonenumber-csharp, that provides extensive resources for validating and manipulating phone numbers of all types. NET Core provide data validation capabilities to make it easier to handle standard data types more robustly. This is particularly true of data like phone numbers, which are typically private data used to deliver both application functionality, such as messaging, and security features like 2-factor authentication.Īpplication development frameworks, including the. Validating user input is important to the security and proper operation of any software application.
