Convert Stream to IRandomAccessStream

Question

I need to convert a Stream into an IRandomAccessStream (in order to create a BitmapDecoder). I tried casting and searching for built-in methods for that in BitmapDecoder but couldn't find any.

So how do I do that?

can you show what code you have or have tried ..this should not be that difficult but it would be nice to see what you have written code wise to see where you have went wrong — MethodMan, Oct 19 '15 at 18:11

@ispiro Your post is a bit old. This `MSDN` [link](https://learn.microsoft.com/en-us/dotnet/standard/io/how-to-convert-between-dotnet-streams-and-winrt-streams) should also help — nam, Mar 29 '19 at 18:24

There is an extension method for that:

Stream stream = GetSomeStream();
IRandomAccessStream randomAccessStream = stream.AsRandomAccessStream();

Just make sure that you have using System.IO at the top of your code file.

Perfect. (Can't accept yet.) I can't believe I didn't see that when searching Intellisense! – ispiro Oct 19 '15 at 18:19

in Visual Basic Method like this...

Dim inputfile As Streams.IRandomAccessStream = System.IO.WindowsRuntimeStreamExtensions.AsRandomAccessStream(stm)
