Attempts to get an unprocessed character string value from source with a
specified tag under the specified encoding rules, if the value is contained in a single
(primitive) encoding.

static bool TryReadPrimitiveCharacterStringBytes(ReadOnlySpan<System::Byte> source, System::Formats::Asn1::AsnEncodingRules ruleSet, System::Formats::Asn1::Asn1Tag expectedTag, [Runtime::InteropServices::Out] ReadOnlySpan<System::Byte> % value, [Runtime::InteropServices::Out] int % bytesConsumed);public static bool TryReadPrimitiveCharacterStringBytes (ReadOnlySpan<byte> source, System.Formats.Asn1.AsnEncodingRules ruleSet, System.Formats.Asn1.Asn1Tag expectedTag, out ReadOnlySpan<byte> value, out int bytesConsumed);static member TryReadPrimitiveCharacterStringBytes : ReadOnlySpan<byte> * System.Formats.Asn1.AsnEncodingRules * System.Formats.Asn1.Asn1Tag * ReadOnlySpan * int -> boolPublic Shared Function TryReadPrimitiveCharacterStringBytes (source As ReadOnlySpan(Of Byte), ruleSet As AsnEncodingRules, expectedTag As Asn1Tag, ByRef value As ReadOnlySpan(Of Byte), ByRef bytesConsumed As Integer) As BooleanParameters
- source
- ReadOnlySpan<Byte>
The buffer containing encoded data.
- ruleSet
- AsnEncodingRules
The encoding constraints to use when interpreting the data.
- expectedTag
- Asn1Tag
The tag to check for before reading.
- value
- ReadOnlySpan<Byte>
On success, receives a slice of the input buffer that corresponds to the value of the Bit String. This parameter is treated as uninitialized.
- bytesConsumed
- Int32
When this method returns, the total number of bytes for the encoded value. This parameter is treated as uninitialized.
Returns
true if the character string value has a primitive encoding;
otherwise, false.
Exceptions
ruleSet is not defined.
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.
Remarks
This method does not determine if the string used only characters defined by the encoding.
