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

TModel

The type of the model object.

Parameters

model
Type: TModel
The model instance to update.
prefix
Type: System::String
The prefix to use when looking up values in the value provider.
includeProperties
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.
ExceptionCondition
ArgumentNullException

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 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.
