Namespace:  System.Windows.Markup
Assembly:  PresentationFramework (in PresentationFramework.dll)

public override Object ConvertFrom(
	ITypeDescriptorContext context,
	CultureInfo culture,
	Object value
)

Parameters

context
Type: System.ComponentModel.ITypeDescriptorContext

A format context that provides information about the environment from which this converter is being invoked.

culture
Type: System.Globalization.CultureInfo

Culture specific information.

value
Type: System.Object

The object to convert.

Return Value

Type: System.Object
Throws an exception in all cases.

ExceptionCondition
NotSupportedException

Cannot perform the conversion.

The ComponentResourceKey type should not use a type converter pathway to convert values (should use markup extensions instead). For this reason, the CanConvertFrom(ITypeDescriptorContext, Type) and CanConvertTo(ITypeDescriptorContext, Type) methods always return false. The ConvertFrom(ITypeDescriptorContext, CultureInfo, Object) and ConvertTo(ITypeDescriptorContext, CultureInfo, Object, Type) methods always throw an exception.
