The [Range] attribute checks whether a property value falls between a minimum and a maximum value.

To attach the metadata defined in the User Profile Metadata class to the User Profile class you need to add a partial class to the project and then use the [Metadata Type] attribute as shown below: As you can see the User Profile class is a partial class and has [Metadata Type] attribute on top of it.

The [Required] attribute indicates that a property value must be provided.

The [String Length] attribute is used to specify the maximum length and optionally the minimum length for a property value.

Inside, it checks whether all the properties of the model class (User Profile) contain valid values. If so, Index view is rendered by passing the profile object as the model data.

If Is Valid returns true, the data is added to the User Profile table and a success view is rendered.

The [Metadata Type] attribute accepts the type of the class that is supplying metadata information to the User Profile class (User Profile Metadata in this case).

Now, add a new controller in the Controllers folder and name it Home Controller.

The [Url] attribute checks whether a property value is a valid URL.

Finally, the [Regular Expression] attribute checks whether a property value matches a pattern as specified by a regular expression.

Add the following code to the Home Controller class.

The Home Controller class contains two versions of the Index() action method.

The recommended approach is to create a metadata class and decorate its properties with data annotation attributes. Add a new class in the Models folder and name it User Profile Metadata.
