Reads a Boolean value from source with a specified tag under the specified encoding rules.

public static bool ReadBoolean (ReadOnlySpan<byte> source, System.Formats.Asn1.AsnEncodingRules ruleSet, out int bytesConsumed, System.Formats.Asn1.Asn1Tag? expectedTag = default);

static member ReadBoolean : ReadOnlySpan<byte> * System.Formats.Asn1.AsnEncodingRules * int * Nullable<System.Formats.Asn1.Asn1Tag> -> bool

Public Shared Function ReadBoolean (source As ReadOnlySpan(Of Byte), ruleSet As AsnEncodingRules, ByRef bytesConsumed As Integer, Optional expectedTag As Nullable(Of Asn1Tag) = Nothing) As Boolean

Parameters

source

ReadOnlySpan<Byte>

The buffer containing encoded data.

ruleSet

AsnEncodingRules

The encoding constraints to use when interpreting the data.

bytesConsumed

Int32

When this method returns, the total number of bytes for the encoded value. This parameter is treated as uninitialized.

expectedTag

Nullable<Asn1Tag>

The tag to check for before reading, or null for the default tag (Universal 1).

Returns

Boolean

The decoded value.

Exceptions

ArgumentOutOfRangeException

ruleSet is not defined.

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 correct for the method.
