Using memory stream with httpClient post about microsoft.io.recyclablememorystream HOT 3 CLOSED

Convert.ToBase64String contains overload with ReadOnlySpan<byte> bytes argument. But you still allocate a string. I'd suggest to try Convert.TryToBase64Chars() instead to and leverage pooling on top of this as much as possible.

@sungam3r thanks for the advice about Convert.TryToBase64Chars(), but I'm forced to use Standard 2.0 because of external libraries. I worry more about the stream.ToArray() and the consequences.

Can you share some sample code of how you're using the StreamContent class with the RMS? I see that StreamContent can be initialized directly with a stream--why not do that?

Alternatively, you could use RMS.GetBuffer(), but you have to use the Length property to know how much of the stream is valid.

But generally, I recommend using the ReadOnlySpan interface.
