override this.WriteBase64Async : byte[] * int * int -> System.Threading.Tasks.Task
Public Overrides Function WriteBase64Async (buffer As Byte(), index As Integer, count As Integer) As Task

Parameters

buffer
Byte[]

Byte array to encode.

index
Int32

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

count
Int32

The number of bytes to write.

The task that represents the asynchronous WriteBase64 operation.

Exceptions

An XmlDictionaryWriter 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-
