PropertyDescriptor..::.GetValue Method

When overridden in a derived class, gets the current value of the property on a component.

Namespace: System.ComponentModel
Assembly: System (in System.dll)

Syntax

Visual Basic (Declaration)

Public MustOverride Function GetValue ( _
    component As Object _
) As Object

Visual Basic (Usage)

Dim instance As PropertyDescriptor
Dim component As Object
Dim returnValue As Object

returnValue = instance.GetValue(component)

public abstract Object GetValue(
    Object component
)

Visual C++

public:
virtual Object^ GetValue(
    Object^ component
) abstract

JScript

public abstract function GetValue(
    component : Object
) : Object

Parameters

component: Type: System..::.Object
The component with the property for which to retrieve the value.

Return Value

Type: System..::.Object
The value of a property for a given component.

Remarks

Typically, this method is implemented through reflection.

This method automatically calls the pre-change method, OnComponentChanging, and post-change method, OnComponentChanged, of the IComponentChangeService.

Notes to Inheritors:

When you override this method, it gets the current value of the property by invoking a "GetMyProperty" method that you need to implement. An exception in that method should pass through.
