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

protected internal bool TryUpdateModel<TModel>(
	TModel model,
	string[] includeProperties,
	IValueProvider valueProvider
)
where TModel : class

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.
valueProvider
Type: System.Web.Mvc.IValueProvider
A dictionary of values that is used to update the model.

Return Value

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

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.
