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

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

public:
 override bool CanConvertFrom(System::ComponentModel::ITypeDescriptorContext ^ context, Type ^ sourceType);

public override bool CanConvertFrom(System.ComponentModel.ITypeDescriptorContext context, Type sourceType);

override this.CanConvertFrom : System.ComponentModel.ITypeDescriptorContext * Type -> bool

Public Overrides Function CanConvertFrom (context As ITypeDescriptorContext, sourceType As Type) As Boolean

Parameters

context: ITypeDescriptorContext

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

sourceType: Type

The type being evaluated for conversion.

Returns

Boolean

false in all cases.

Exceptions

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.
