Definition

Namespace:

System.Formats.Asn1

Assembly:

System.Formats.Asn1.dll

Source:

AsnDecoder.UtcTime.cs

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

public static DateTimeOffset ReadUtcTime (ReadOnlySpan<byte> source, System.Formats.Asn1.AsnEncodingRules ruleSet, out int bytesConsumed, int twoDigitYearMax = 2049, System.Formats.Asn1.Asn1Tag? expectedTag = default);

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

Public Shared Function ReadUtcTime (source As ReadOnlySpan(Of Byte), ruleSet As AsnEncodingRules, ByRef bytesConsumed As Integer, Optional twoDigitYearMax As Integer = 2049, Optional expectedTag As Nullable(Of Asn1Tag) = Nothing) As DateTimeOffset

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.

twoDigitYearMax

Int32

The largest year to represent with this value. The default value, 2049, represents the 1950-2049 range for X.509 certificates.

expectedTag

Nullable<Asn1Tag>

The tag to check for before reading, or null for the default tag (Universal 24).

Returns

DateTimeOffset

The decoded value.

Exceptions

ArgumentOutOfRangeException

ruleSet is not defined.

-or-

twoDigitYearMax is not in the range [99, 9999].

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.
