Parameters

context: ITypeDescriptorContext

An ITypeDescriptorContext that provides a format context, which can be used to extract additional information about the environment this converter is being invoked from. This parameter or properties of this parameter can be null.

A CultureInfo to provide locale information.

value: Object

The Object to convert.

destinationType: Type

The Type to convert the object to.

Returns

Remarks

The ConvertTo method is specialized to convert objects of type Keys or Int32. In this case, it will return an object of type String. Otherwise, it defers evaluation to the base implementation of this method.

Notes to Inheritors

Override this method to provide your own conversion requirements.

The context parameter can be used to extract additional information about the environment this converter is being invoked from. This may be null, so you should always check for this return value. Also, properties on the context object may also return null.
