WindowsRuntimeBufferExtensions Class
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.

public static class WindowsRuntimeBufferExtensions
The WindowsRuntimeBufferExtensions type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
.gif "Public method") .gif "Static member") |
AsBuffer(array<Byte>[]()[]) | Returns a Windows.Storage.Streams.IBuffer interface that represents the specified byte array. |
|
AsBuffer(array<Byte>[]()[], Int32, Int32) | Returns a Windows.Storage.Streams.IBuffer interface that represents a range of bytes in the specified byte array. |
|
AsBuffer(array<Byte>[]()[], Int32, Int32, Int32) | Returns a Windows.Storage.Streams.IBuffer interface that represents a range of bytes in the specified byte array. Optionally sets the Length property of the IBuffer to a value that is less than the capacity. |
|
AsStream | Returns a stream that represents the same memory that the specified Windows.Storage.Streams.IBuffer interface represents. |
|
CopyTo(IBuffer, array<Byte>[]()[]) | Copies all bytes from the source buffer (Windows.Storage.Streams.IBuffer) to the destination array, starting at offset 0 (zero) in both. |
|
CopyTo(IBuffer, IBuffer) | Copies all bytes from the source buffer (Windows.Storage.Streams.IBuffer) to the destination buffer, starting at offset 0 (zero) in both. |
|
CopyTo(array<Byte>[]()[], IBuffer) | Copies all bytes from the source array to the destination buffer (Windows.Storage.Streams.IBuffer), starting at offset 0 (zero) in both. The method does not update the length of the destination buffer. |
|
CopyTo(IBuffer, UInt32, array<Byte>[]()[], Int32, Int32) | Copies bytes from the source buffer (Windows.Storage.Streams.IBuffer) to the destination array, specifying the starting index in the source buffer, the starting index in the destination array, and the number of bytes to copy. |
|
CopyTo(IBuffer, UInt32, IBuffer, UInt32, UInt32) | Copies bytes from the source buffer (Windows.Storage.Streams.IBuffer) to the destination buffer, specifying the starting index in the source, the starting index in the destination, and the number of bytes to copy. |
|
CopyTo(array<Byte>[]()[], Int32, IBuffer, UInt32, Int32) | Copies bytes from the source array to the destination buffer (Windows.Storage.Streams.IBuffer), specifying the starting index in the source array, the starting index in the destination buffer, and the number of bytes to copy. The method does not update the Length property of the destination buffer. |
|
GetByte | Returns the byte at the specified offset in the specified Windows.Storage.Streams.IBuffer interface. |
|
GetWindowsRuntimeBuffer(MemoryStream) | Returns a Windows.Storage.Streams.IBuffer interface that represents the same memory as the specified memory stream. |
|
GetWindowsRuntimeBuffer(MemoryStream, Int32, Int32) | Returns a Windows.Storage.Streams.IBuffer interface that represents a region within the memory that the specified memory stream represents. |
|
IsSameData | Returns a value that indicates whether two buffers (Windows.Storage.Streams.IBuffer objects) represent the same underlying memory region. |
|
ToArray(IBuffer) | Returns a new array that is created from the contents of the specified buffer (Windows.Storage.Streams.IBuffer). The size of the array is the value of the Length property of the IBuffer. |
|
ToArray(IBuffer, UInt32, Int32) | Returns a new array that is created from the contents of the specified buffer (Windows.Storage.Streams.IBuffer), starting at a specified offset and including a specified number of bytes. |
