WindowsRuntimeBufferExtensions::CopyTo Method (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.
This API is not CLS-compliant. Namespace: System.Runtime.InteropServices.WindowsRuntime
Assembly: System.Runtime.WindowsRuntime (in System.Runtime.WindowsRuntime.dll)
[ExtensionAttribute] [CLSCompliantAttribute(false)] public: static void CopyTo( array<unsigned char>^ source, int sourceIndex, IBuffer^ destination, unsigned int destinationIndex, int count )
Parameters
- source
- Type: array<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 array<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).| Exception | Condition |
|---|---|
| ArgumentNullException | source or destination is nullptr. |
| 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. -or- Copying count bytes, beginning at destinationIndex, would exceed the capacity of destination. |
