Reads the next value as a BIT STRING with a specified tag, returning the contents as a ReadOnlyMemory<T> over the original data.
public bool TryReadPrimitiveBitString (out int unusedBitCount, out ReadOnlyMemory<byte> value, System.Formats.Asn1.Asn1Tag? expectedTag = default);member this.TryReadPrimitiveBitString : int * ReadOnlyMemory * Nullable<System.Formats.Asn1.Asn1Tag> -> boolPublic Function TryReadPrimitiveBitString (ByRef unusedBitCount As Integer, ByRef value As ReadOnlyMemory(Of Byte), Optional expectedTag As Nullable(Of Asn1Tag) = Nothing) As BooleanParameters
- unusedBitCount
- Int32
On success, receives the number of bits in the last byte which were reported as "unused" by the writer.
- value
- ReadOnlyMemory<Byte>
On success, receives a ReadOnlyMemory<T> over the original data corresponding to the value of the BIT STRING.
The tag to check for before reading, or null for the default tag (Universal 1).
Returns
true and advances the reader if the BIT STRING value had a primitive encoding,
false and does not advance the reader if it had a constructed encoding.
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.
