How to take a stringbuilder and convert it to a streamReader?

Question

How to take a stringbuilder and convert it to a stream?

SO my stringbuilder has to be converted into a :

StreamReader stream = ????

Update

I tried using a stringreader like:

StringReader sr = new StringReader(sb.ToString());
StreamReader stream = new StreamReader(sr);

but that doesn't work?

Answer 1

Use ToString to convert the StringBuilder into a String, and use a StringReader to wrap the String as a Stream.

Answer 2

If using a StreamReader is a requirement then convert the string to a memory stream and then create a new StreamReader using that object:

StreamReader reader= new StreamReader(
                new MemoryStream(Encoding.ASCII.GetBytes(sb.ToString())));
