WindowsRuntimeBufferExtensions.IsSameData Method

.NET Framework (current version)

Returns a value that indicates whether two buffers (Windows.Storage.Streams.IBuffer objects) represent the same underlying memory region.

This API is not CLS-compliant. 

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

public static bool IsSameData(
	this IBuffer buffer,
	IBuffer otherBuffer


Type: IBuffer

The first buffer.

Type: IBuffer

The second buffer.

Return Value

Type: System.Boolean
true if the memory regions that are represented by the two buffers have the same starting point; otherwise, false.

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. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

It is not necessary for the two memory regions to be identical. The Capacity and Length properties of the two IBuffer instances can be different.

For IBuffer instances that represent managed arrays, this method is preferable to comparing pointers, because it avoids pinning the backing arrays.
