Remarks

The [Overload:System.Web.Mvc.Controller.TryUpdateModel``1] method is like the [Overload:System.Web.Mvc.Controller.UpdateModel``1] method except that the [Overload:System.Web.Mvc.Controller.TryUpdateModel``1] method does not throw an InvalidOperationException exception if the updated model state is not valid.

For more information model validation, see the entry Input Validation vs. Model Validation in ASP.NET MVC on Brad Wilson's blog.

Security noteSecurity Note

Use one of the [Overload:System.Web.Mvc.Controller.TryUpdateModel``1] methods that takes either a list of properties to include (a whitelist) or a list of properties to exclude (a blacklist). If no explicit whitelist or blacklist is passed, the [Overload:System.Web.Mvc.Controller.TryUpdateModel``1] method tries to update every public property in the model for which there is a corresponding value in the request. A malicious user could exploit this in order to update properties that you do not intend to provide access to.
