Public Function TryReadUInt32 (ByRef value As UInteger, Optional expectedTag As Nullable(Of Asn1Tag) = Nothing) As Boolean

Parameters

value

UInt32

On success, receives the decoded value.

expectedTag

Nullable<Asn1Tag>

The tag to check for before reading, or null for the default tag (Universal 2).

Returns
