Syntax

'Declaration
Protected Friend Function TryUpdateModel(Of TModel As Class) ( _
    model As TModel, _
    includeProperties As String(), _
    valueProvider As IValueProvider _
) As Boolean
protected internal bool TryUpdateModel<TModel>(
    TModel model,
    string[] includeProperties,
    IValueProvider valueProvider
)
where TModel : class
protected public:
generic<typename TModel>
where TModel : ref class
bool TryUpdateModel(
    TModel model, 
    array<String^>^ includeProperties, 
    IValueProvider^ valueProvider
)

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.

Return Value

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

Remarks

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.
