Stream wrapper to make Stream seekable?

Question

I have a readonly System.IO.Stream implementation that is not seekable (and its Position always returns 0). I need to send it to a consumer that do

Answer 1

I just use the MakeStreamSeekable method from the Amazon SDK:

---

MakeStreamSeekable Method (input)

Converts a non-seekable stream into a System.IO.MemoryStream. A MemoryStream's position can be moved arbitrarily.

Declaration Syntax

C#

public static Stream MakeStreamSeekable(
    Stream input
)

Parameters

*input* ([Stream][2]) The stream to be converted

Return Value

A seekable MemoryStream

Remarks

MemoryStreams use byte arrays as their backing store. Please use this judicially as it is likely that a very large stream will cause system resources to be used up.
