WindowsRuntimeBufferExtensions.CopyTo Method (, UInt32, Byte[], Int32, Int32)

May 11, 2014

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.

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.

This API is not CLS-compliant. 

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

public static void CopyTo(
	this IBuffer source,
	uint sourceIndex,
	byte[] destination,
	int destinationIndex,
	int count


Type: Windows.Storage.Streams.IBuffer
The buffer to copy data from.
Type: System.UInt32
The index in source to begin copying data from.
Type: System.Byte []
The array to copy data to.
Type: System.Int32
The index in destination to begin copying data to.
Type: System.Int32
The number of bytes to copy.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IBuffer. When you use instance method syntax to call this method, omit the first parameter.
