Controller::TryUpdateModel<TModel> Method (TModel, String, array<String>)

Updates the specified model instance using values from the controller's current value provider, a prefix, and included properties.

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

protected public:
generic<typename TModel>
where TModel : ref class
bool TryUpdateModel(
	TModel model, 
	String^ prefix, 
	array<String^>^ includeProperties

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.

Return Value

Type: System::Boolean
true if the update is successful; otherwise, false.


The model parameter or the ValueProvider property is nullptr.

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 the generic parameter. The TryUpdateModel() method is like the UpdateModel() method except that the TryUpdateModel() method does not throw an InvalidOperationException exception when the updated model state is not valid.
