+Summary: StreamReader.ReadToEnd loops forever
+Description of Problem:
+When using StreamReader.ReadToEnd with Encoding.ASCII it enters and never
+ending loop.
+Steps to reproduce the problem:
+1. Fill a Stream object with text ( I used HttpWebResponse.GetResponseStream)
+2. Initialize a StreamReader using the Stream object
+3. Call .ReadToEnd to try to return a String.
+<begining of code>
+  HttpWebResponse myRes = (HttpWebResponse)myReq.GetResponse();
+  Stream respStream = myRes.GetResponseStream();
+  int respLength=(int)myRes.ContentLength;
+  StreamReader reader = 
+	new StreamReader(respStream, Encoding.ASCII,true,respLength);
+  String respHTML = reader.ReadToEnd();
+<End of Code>
+Actual Results:
+The code hangs at "String respHTML = reader.ReadToEnd();"
+Can break with ^c
+Expected Results:
+ReadToEnd should return a String with the contents of the respStream
+How often does this happen? 
+Every time I run the code.
+Additional Information:
+I changed the "while ((len = Read (buffer, 0, size)) != 0)..." in
+StreamReader.cs .ReadToEnd to the line
+"if ((len = Read (buffer, 0, size)) != 0)". Then it worked.
+As long as the code reads from index 0 in "buffer" it always will report a
+length >0 if there is any from the begining.
