Parameters

context
Type: System.ComponentModel..::.ITypeDescriptorContext

An ITypeDescriptorContext that provides a format context.

culture
Type: System.Globalization..::.CultureInfo

A CultureInfo. If nullNothingnullptra null reference (Nothing in Visual Basic) is passed, the current culture is assumed.

value
Type: System..::.Object

The Object to convert.

destinationType
Type: System..::.Type

The Type to convert the value parameter to.

Return Value

Type: System..::.Object

An Object that represents the converted value.

ExceptionCondition
ArgumentNullException

The destinationType parameter is nullNothingnullptra null reference (Nothing in Visual Basic).

NotSupportedException

The conversion cannot be performed.

The most common types to convert are to and from a string object. This implementation calls ToString on the object if the object is valid and if the destination type is a string.

Use the context parameter to extract additional information about the environment from which this converter is invoked. This parameter can be nullNothingnullptra null reference (Nothing in Visual Basic), so always check it. Also, properties on the context object can return nullNothingnullptra null reference (Nothing in Visual Basic).
