Question

I have a MemoryStream object which is passed by Stream type parameter
(Stream is abstract class in C#).

I want to clone it to create another separate MemoryStream object with current position of the original and to create also a new XMLReader out of it, so I will be able to read its content.

This is what I did, and it’s not working (debugging the line marked with //* -> newReader has got {None} value)
Assumption: you are inside a method and have Stream currentStream reference.

var x = new XmlReaderSettings();
x.IgnoreWhitespace = true;  

using (var newMemoryStream = new MemoryStream())
{
     stream.CopyTo(newMemoryStream);

     using (var newReader = XmlReader.Create(newMemoryStream,x)) //*
     {
                
       Doing some stuff...

     }
}

I have solved my problem! 🙂
The things which were missing are marked with //*.
Here is the code as it should be:

var xmlReaderSettings = new XmlReaderSettings();

stream.Position = 0;//*
xmlReaderSettings.IgnoreWhitespace = true;
using (var newMemoryStream = new MemoryStream())
{
    stream.CopyTo(newMemoryStream);
    newMemoryStream.Position = 0;  //*
    using (var newReader = XmlReader.Create(newMemoryStream, xmlReaderSettings))
    {
        newReader.MoveToContent(); //*

        Doing some stuff...
    }
}
