Controller.UpdateModel<TModel> Method (TModel, String)
Updates the specified model instance using values from the controller's current value provider and a prefix.
Assembly: System.Web.Mvc (in System.Web.Mvc.dll)
protected internal void UpdateModel<TModel>( TModel model, string prefix ) where TModel : class
Type Parameters
- TModel
The type of the model object.
Parameters
- model
- Type: TModel
The model instance to update.
- prefix
- Type: System.String
A prefix to use when looking up values in the value provider.
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.
 Security Note |
|---|
You should use one of the UpdateModel() methods that take either a list of included properties (a white list) or a list of excluded properties (a black list). If no explicit white list or black list is passed, the UpdateModel() method tries to update every public property of your model for which there is a corresponding value in the request. A malicious user could exploit this in order to update properties that you do not intend to provide access to. |
