XmlReader.ReadValueChunkAsync(Char[], Int32, Int32) XmlReader.ReadValueChunkAsync(Char[], Int32, Int32) XmlReader.ReadValueChunkAsync(Char[], Int32, Int32) XmlReader.ReadValueChunkAsync(Char[], Int32, Int32) Method

Definition

Asynchronously reads large streams of text embedded in an XML document.

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

The array of characters that serves as the buffer to which the text contents are written. This value cannot be null.

index
Int32 Int32 Int32 Int32

The offset within the buffer where the XmlReader can start to copy the results.

count
Int32 Int32 Int32 Int32

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

Returns

The number of characters read into the buffer. The value zero is returned when there is no more text content.

Exceptions

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 ReadValueChunk, with the same functionality. To use this method, you must set the Async flag to true.
