Public NotInheritable Class AsnWriter

Inheritance: Object
AsnWriter

Constructors

AsnWriter(AsnEncodingRules, Int32)	Initializes a new instance of AsnWriter with a given set of encoding rules and an initial capacity.
AsnWriter(AsnEncodingRules)	Create a new AsnWriter with a given set of encoding rules.

Properties

RuleSet

Gets the encoding rules in use by this writer.

Methods

CopyTo(AsnWriter)	Copy the value of this writer into another.
Encode()	Return a new array containing the encoded value.
Encode(Span<Byte>)	Writes the encoded representation of the data to `destination`.
EncodedValueEquals(AsnWriter)	Determines if Encode() would produce an output identical to `other`.
EncodedValueEquals(ReadOnlySpan<Byte>)	Determines if Encode() would produce an output identical to `other`.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetEncodedLength()	Gets the number of bytes that would be written by TryEncode(Span<Byte>, Int32).
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
PopOctetString(Nullable<Asn1Tag>)	Indicate that the open Octet String with the tag UNIVERSAL 4 is closed, returning the writer to the parent context.
PopSequence(Nullable<Asn1Tag>)	Indicate that the open Sequence with the specified tag is closed, returning the writer to the parent context.
PopSetOf(Nullable<Asn1Tag>)	Indicate that the open Set-Of with the specified tag is closed, returning the writer to the parent context.
PushOctetString(Nullable<Asn1Tag>)	Begin writing an Octet String value with a specified tag.
PushSequence(Nullable<Asn1Tag>)	Begin writing a Sequence with a specified tag.
PushSetOf(Nullable<Asn1Tag>)	Begin writing a Set-Of with a specified tag.
Reset()	Reset the writer to have no data, without releasing resources.
ToString()	Returns a string that represents the current object. (Inherited from Object)
TryEncode(Span<Byte>, Int32)	Attempts to write the encoded representation of the data to `destination`.
WriteBitString(ReadOnlySpan<Byte>, Int32, Nullable<Asn1Tag>)	Write a Bit String value with a specified tag.
WriteBoolean(Boolean, Nullable<Asn1Tag>)	Write a Boolean value with a specified tag.
WriteCharacterString(UniversalTagNumber, ReadOnlySpan<Char>, Nullable<Asn1Tag>)	Write the provided string using the specified encoding type using the specified tag corresponding to the encoding type.
WriteCharacterString(UniversalTagNumber, String, Nullable<Asn1Tag>)	Write the provided string using the specified encoding type using the specified tag corresponding to the encoding type.
WriteEncodedValue(ReadOnlySpan<Byte>)	Write a single value which has already been encoded.
WriteEnumeratedValue(Enum, Nullable<Asn1Tag>)	Write a non-[FlagsAttribute] enum value as an Enumerated with tag UNIVERSAL 10.
WriteEnumeratedValue<TEnum>(TEnum, Nullable<Asn1Tag>)	Write a non-[FlagsAttribute] enum value as an Enumerated with tag UNIVERSAL 10.
WriteGeneralizedTime(DateTimeOffset, Boolean, Nullable<Asn1Tag>)	Write the provided DateTimeOffset as a GeneralizedTime with a specified UNIVERSAL 24, optionally excluding the fractional seconds.
WriteInteger(BigInteger, Nullable<Asn1Tag>)	Write an Integer value with a specified tag.
WriteInteger(Int64, Nullable<Asn1Tag>)	Write an Integer value with a specified tag.
WriteInteger(ReadOnlySpan<Byte>, Nullable<Asn1Tag>)	Write an Integer value with a specified tag.
WriteInteger(UInt64, Nullable<Asn1Tag>)	Write an Integer value with a specified tag.
WriteIntegerUnsigned(ReadOnlySpan<Byte>, Nullable<Asn1Tag>)	Write an Integer value with a specified tag.
WriteNamedBitList(BitArray, Nullable<Asn1Tag>)	Write a bit array value as a NamedBitList with a specified tag.
WriteNamedBitList(Enum, Nullable<Asn1Tag>)	Write a [FlagsAttribute] enum value as a NamedBitList with a specified tag.
WriteNamedBitList<TEnum>(TEnum, Nullable<Asn1Tag>)	Write a [FlagsAttribute] enum value as a NamedBitList with a specified tag.
WriteNull(Nullable<Asn1Tag>)	Write NULL with a specified tag.
WriteObjectIdentifier(ReadOnlySpan<Char>, Nullable<Asn1Tag>)	Write an Object Identifier with a specified tag.
WriteObjectIdentifier(String, Nullable<Asn1Tag>)	Write an Object Identifier with a specified tag.
WriteOctetString(ReadOnlySpan<Byte>, Nullable<Asn1Tag>)	Write an Octet String value with a specified tag.
WriteUtcTime(DateTimeOffset, Int32, Nullable<Asn1Tag>)	Write the provided value as a UTCTime with a specified tag, provided the year is in the allowed range.
WriteUtcTime(DateTimeOffset, Nullable<Asn1Tag>)	Write the provided value as a UTCTime with a specified tag, accepting the two-digit year as valid in context.
