Definition

Namespace:: System.Xml

Assemblies:: System.Xml.ReaderWriter.dll, System.Xml.dll, netstandard.dll

Asynchronously reads the element and decodes the BinHex content.

public:
 virtual System::Threading::Tasks::Task<int> ^ ReadElementContentAsBinHexAsync(cli::array <System::Byte> ^ buffer, int index, int count);

Public Overridable Function ReadElementContentAsBinHexAsync (buffer As Byte(), index As Integer, count As Integer) As Task(Of Integer)

Parameters

buffer: Byte[]

The buffer into which to copy the resulting text. This value cannot be null.

index: Int32

The offset into the buffer where to start copying the result.

count: Int32

The maximum number of bytes to copy into the buffer. The actual number of bytes copied is returned from this method.

Returns

Task<Int32>

The number of bytes written to the buffer.

Exceptions

InvalidOperationException

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

Remarks

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