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

protected public:
generic<typename TModel>
where TModel : ref class 
void UpdateModel(
	TModel model, 
	String^ prefix, 
	array<String^>^ includeProperties, 
	array<String^>^ excludeProperties, 
	IValueProvider^ valueProvider

Type Parameters


The type of the model object.


Type: TModel

The model instance to update.

Type: System::String

The prefix to use when looking up values in the value provider.

Type: array<System::String>

A list of properties of the model to update.

Type: array<System::String>

A list of properties to explicitly exclude from the update. These are excluded even if they are listed in the includeProperties parameter list.

Type: System.Web.Mvc::IValueProvider

A dictionary of values that is used to update the model.

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 [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.
