Reads the next value as a character with a specified tag, returning the contents as an unprocessed ReadOnlyMemory<T> over the original data.

public:
 bool TryReadPrimitiveCharacterStringBytes(System::Formats::Asn1::Asn1Tag expectedTag, [Runtime::InteropServices::Out] ReadOnlyMemory<System::Byte> % contents);

public bool TryReadPrimitiveCharacterStringBytes (System.Formats.Asn1.Asn1Tag expectedTag, out ReadOnlyMemory<byte> contents);

member this.TryReadPrimitiveCharacterStringBytes : System.Formats.Asn1.Asn1Tag * ReadOnlyMemory -> bool

Public Function TryReadPrimitiveCharacterStringBytes (expectedTag As Asn1Tag, ByRef contents As ReadOnlyMemory(Of Byte)) As Boolean

Parameters

expectedTag

Asn1Tag

The tag to check for before reading.

contents

ReadOnlyMemory<Byte>

On success, receives a ReadOnlyMemory<T> over the original data corresponding to the value of the character string.

Returns

Boolean

true and advances the reader if the character string value had a primitive encoding, false and does not advance the reader if it had a constructed encoding.

Exceptions

AsnContentException

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.

ArgumentException

expectedTag.TagClass is Universal, but expectedTag.TagValue is not a character string tag type.

Remarks

This method does not determine if the string used only characters defined by the encoding.
