Data Annotations in C# are used as validators in an ASP.NET Core Web API controller for model validation. • We'll show you how to add a validator as an attribute to a property in the model. It can then be used with the ModelState instance for an action in a controller. • In-addition, .NET provides the ability to create a custom validator. We'll show you how to code one in C# and how to apply it to an existing model. • Finally, we'll show you the difference between using Data Annotations in MVC against an API controller which is used with Web API. • 💻 Download the code example for this demo 💻 • https://www.roundthecode.com/dotnet-c... • 📖 Learn .NET and C# with our online courses 📖 • https://www.roundthecode.com/dotnet-c... • ► More information: • https://www.roundthecode.com/dotnet-t... • ► Chapters • 0:00 Data Annotations for model validation • 0:22 Learn with .NET online courses • 0:31 Default Data Annotation validators • 2:44 Custom Data Annotation validator • 4:49 Download the code sample • #dataannotation #webapi #dotnet
