Controller.UpdateModel<TModel> Method (TModel, String, String[], IDictionary<String, ValueProviderResult>)

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

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

protected internal void UpdateModel<TModel>(
	TModel model,
	string prefix,
	string[] includeProperties,
	IDictionary<string, ValueProviderResult> valueProvider
where TModel : class

Type Parameters


The type of the model object.


Type: TModel
The model instance to update.
Type: System.String
A prefix to use when looking up values in the value provider.
Type: System.String[]
A list of properties of the model to update.
Type: System.Collections.Generic.IDictionary<String, ValueProviderResult>
A dictionary of values 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 the generic parameter. The UpdateModel() method is like the TryUpdateModel() method except that the UpdateModel() method throws an InvalidOperationException exception when the updated model state is not valid.
