XmlWriter.WriteBase64Async(Byte[], Int32, Int32) XmlWriter.WriteBase64Async(Byte[], Int32, Int32) XmlWriter.WriteBase64Async(Byte[], Int32, Int32) XmlWriter.WriteBase64Async(Byte[], Int32, Int32) Method

Definition

Asynchronously encodes the specified binary bytes as Base64 and writes out the resulting text.

public:
 virtual System::Threading::Tasks::Task ^ WriteBase64Async(cli::array <System::Byte> ^ buffer, int index, int count);
public virtual System.Threading.Tasks.Task WriteBase64Async (byte[] buffer, int index, int count);
abstract member WriteBase64Async : byte[] * int * int -> System.Threading.Tasks.Task
override this.WriteBase64Async : byte[] * int * int -> System.Threading.Tasks.Task
Public Overridable Function WriteBase64Async (buffer As Byte(), index As Integer, count As Integer) As Task

Parameters

buffer
Byte[]

Byte array to encode.

index
Int32 Int32 Int32 Int32

The position in the buffer indicating the start of the bytes to write.

count
Int32 Int32 Int32 Int32

The number of bytes to write.

Returns

The task that represents the asynchronous WriteBase64 operation.

Exceptions

An XmlWriter method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

-or-

An XmlWriter asynchronous method was called without setting the Async flag to true. In this case, InvalidOperationException is thrown with the message "Set XmlWriterSettings.Async to true if you want to use Async Methods."

Remarks

This is the asynchronous version of WriteBase64, with the same functionality. To use this method, you must set the Async flag to true.
