Public Shared Function ChangeType( _
   ByVal value As Object, _
   ByVal conversionType As Type _
) As Object

Dim conversionType As Type
Dim value As Object

public static object ChangeType( 
   object value,
   Type conversionType
)

public:
static Object^ ChangeType( 
   Object^ value,
   Type^ conversionType
)

Parameters

value: An Object that implements the IConvertible interface.
conversionType: The Type to which value is to be converted.

Return Value

An object whose Type is conversionType (or conversionType's underlying type if conversionType is Nullable<>) and whose value is equivalent to value. -or- a null reference, if value is a null reference and conversionType is not a value type.

Remarks

This method exists as a workaround to System.Convert.ChangeType(Object, Type) which does not handle nullables as of version 2.0 (2.0.50727.42) of the .NET Framework. The idea is that this method will be deleted once Convert.ChangeType is updated in a future version of the .NET Framework to handle nullable types, so we want this to behave as closely to Convert.ChangeType as possible. This method was written by Peter Johnson at: http://aspalliance.com/author.aspx?uId=1026.
