Reads the next value as an Enumerated with a specified tag, converting it to the non-[FlagsAttribute] enum specified by enumType.

public Enum ReadEnumeratedValue (Type enumType, System.Formats.Asn1.Asn1Tag? expectedTag = default);
member this.ReadEnumeratedValue : Type * Nullable<System.Formats.Asn1.Asn1Tag> -> Enum
Public Function ReadEnumeratedValue (enumType As Type, Optional expectedTag As Nullable(Of Asn1Tag) = Nothing) As Enum

Parameters

enumType
Type

Type object representing the destination type.

expectedTag
Nullable<Asn1Tag>

The tag to check for before reading, or null for the default tag (Universal 10).

Returns

The Enumerated value converted to a enumType.

Exceptions

The next value does not have the correct tag.

-or-

The length encoding is not valid under the current encoding rules.

-or-

The contents are not valid under the current encoding rules.

-or-

The encoded value is too big to fit in a enumType value.

enumType is not an enum type.

-or-

enumType was declared with FlagsAttribute.

-or-

enumType.TagClass is Universal, but enumType.TagValue is not correct for the method.

enumType is null.

Remarks

This method does not validate that the return value is defined within enumType.
