Controller.UpdateModel(TModel) Method (TModel, String[])

Updates the specified model instance using values from the controller object's current value provider.

Namespace:  System.Web.Mvc
Assembly:  System.Web.Mvc (in System.Web.Mvc.dll)

JScript does not support generic types or methods.

Type Parameters

TModel

The type of the model object.

Parameters

model
Type: TModel
The model instance to update.
includeProperties
Type: System.String[]
A list of properties of the model to update.

You do not have to explicitly specify the generic parameter TModel. Instead, you can let the C# or Visual Basic type inference engine determine the generic parameter TModel by omitting it.

The TryUpdateModel method is like the UpdateModel method except that the TryUpdateModel method does not throw an InvalidOperationException exception if the updated model state is not valid.

Security noteSecurity Note:

Use one of the TryUpdateModel 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 TryUpdateModel 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.
