Certificate.DecodeExtension Method (Extension, IntPtr, Type)

Decodes the specified extension and returns an object of the specified type that is instantiated with the decoded bytes.

[Visual Basic]
Overloads Protected Shared Function DecodeExtension( _
   ByVal extension As Extension, _
   ByVal oid As IntPtr, _
   ByVal returnType As Type _
) As Object

[C#]
protected static object DecodeExtension(
   Extension extension,
   IntPtr oid,
   Type returnType
);

Parameters

extension: The certificate extension to decode.
oid: The Object Identifier of the structure.
returnType: A Type instance. See remarks.

Return Value

An object of the type returnType.

Remarks

The specified type should have a public constructor that takes an IntPtr and an int as parameters [in that order]. The IntPtr is a pointer to the decoded buffer and the int contains the number of decoded bytes. The type should not keep the IntPtr reference after construction of an instance, because the memory is freed when the DecodeExtension method returns.

Exceptions

Exception Type	Condition
ArgumentNullException	One of the parameters is a null reference (Nothing in Visual Basic).
CertificateException	An error occurs while decoding the certificate extension.
