For apps that target Windows Phone OS 7.0 and 7.1, do not use any members of this type in your app. If you do, your code will throw a MethodAccessException. This type is security-critical, which restricts it to internal use by the .NET Framework for Windows Phone class library.

Syntax

<ExtensionAttribute> _
<CLSCompliantAttribute(False)> _
Public Shared Function ToArray ( _
    source As IBuffer, _
    sourceIndex As UInteger, _
    count As Integer _
) As Byte()

[CLSCompliantAttribute(false)]
public static byte[] ToArray(
    this IBuffer source,
    uint sourceIndex,
    int count
)

Parameters

source
Type: Windows.Storage.Streams..::.IBuffer
The buffer whose contents populate the new array.

sourceIndex
Type: System..::.UInt32
The index in source to begin copying data from.

count
Type: System..::.Int32
The number of bytes to copy.
