WindowsRuntimeBufferExtensions.AsBuffer Method (Byte[])

.NET Framework 4.6 and 4.5

Returns a Windows.Storage.Streams.IBuffer interface that represents the specified byte array.

This API is not CLS-compliant. 

Namespace:  System.Runtime.InteropServices.WindowsRuntime
Assembly:  System.Runtime.WindowsRuntime (in System.Runtime.WindowsRuntime.dll)

public static IBuffer AsBuffer(
	this byte[] source


Type: System.Byte[]

The array to represent.

Return Value

Type: IBuffer
A Windows.Storage.Streams.IBuffer interface that represents the specified byte array.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Byte[]. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).


source is null.

The array you pass to source becomes the backing store for the IBuffer interface that is returned. The Length and Capacity properties of the IBuffer are set to the size of source. Any changes you make by using the IBuffer (for example, by calling the CopyTo(Byte[], Int32, IBuffer, UInt32, Int32) extension method with the IBuffer as destination) are reflected in the backing store.
