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

.NET Framework 4.5

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.

This API is not CLS-compliant. 

Namespace:  System.Runtime.InteropServices.WindowsRuntime
Assembly:  System.Runtime.WindowsRuntime (in System.Runtime.WindowsRuntime.dll)
[CLSCompliantAttribute(false)]
public static void CopyTo(
	this byte[] source,
	int sourceIndex,
	IBuffer destination,
	uint destinationIndex,
	int count
)

Parameters

source
Type: System.Byte[]

The array to copy data from.

sourceIndex
Type: System.Int32

The index in source to begin copying data from.

destination
Type: IBuffer

The buffer to copy data to.

destinationIndex
Type: System.UInt32

The index in destination to begin copying data to.

count
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 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).
ExceptionCondition
ArgumentNullException

source or destination is null.

ArgumentOutOfRangeException

count, sourceIndex, or destinationIndex is less than 0 (zero).

ArgumentException

sourceIndex is greater than or equal to the length of source.

-or-

The number of bytes in source, beginning at sourceIndex, is less than count.
