ComponentResourceKeyConverter.CanConvertFrom Method (ITypeDescriptorContext, Type)

.NET Framework 4

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Determines whether an object of the specified type can be converted to an instance of ComponentResourceKey, using the specified context. Always returns false.

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

Syntax

C++

public override bool CanConvertFrom(
	ITypeDescriptorContext context,
	Type sourceType
)

Parameters

context: Type: System.ComponentModel.ITypeDescriptorContext
A format context that provides information about the environment from which this converter is being invoked.

sourceType: Type: System.Type
The type being evaluated for conversion.

Return Value

Type: System.Boolean
false in all cases.

Exceptions

Exception	Condition
ArgumentNullException	sourceType is null.

Remarks

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.
