27-Jun-2023Sure. Model binding in ASP.NET Core MVC is the process of converting HTTP request data into .NET objects. This allows controller actions to work directly with model types (passed in as method arguments), rather than HTTP requests.
Model binding is done automatically by MVC for most simple types, such as strings, integers, and dates. For more complex types, such as custom classes, you need to provide a model binder. A model binder is a class that knows how to convert HTTP request data into a specific type.
Here is an example of how model binding works:
C#
In this example, the
Index()action method creates a newStudentobject. TheModelBinder.Bind()method then binds the HTTP request data to theStudentobject. TheModelBinder.Bind()method will automatically convert the HTTP request data into the appropriate types for theStudentobject. For example, if the HTTP request contains aNameproperty, theModelBinder.Bind()method will convert the value of theNameproperty into astringand assign it to theNameproperty of theStudentobject.Once the
ModelBinder.Bind()method has completed, theStudentobject will contain the data from the HTTP request. TheIndex()action method then returns theStudentobject to the view.Model binding is a powerful feature that can help you to simplify your code and to make your applications more maintainable. If you are using ASP.NET Core MVC, I encourage you to use model binding to convert HTTP request data into .NET objects.
