如何将字符串注入NetworkStream，以便可以通过C＃中的XmlReader.ReadAsync读取？

Question

I am reading XML data from the NetworkStream like follows.

using (XmlReader xmlReader = XmlReader.Create(stream, new XmlReaderSettings() { Async = true }))
{
    try
    {                    
         while (await xmlReader.ReadAsync())
         {
         ...

I would like to call stream.Inject("</stop>") so it can be read in the while loop above. I know I would have to write a wrapper class around Stream and implement the Inject method and override the ReadAsync method. However I have no idea how to achieve that. Would someone show me how something like that is done (I just can't imagine where in my Inject method the additional string should be added)?

NetworkStream is a Stream so that means you can write any chunk of data into it, including XML strings. Of course, you have to do some conversion like:

byte[] data = System.Text.Encoding.UTF8.GetBytes(longXmlString);
networkSteram.Write(data);
