title: Memory efficiency :Passing Html code of aspx page through codebehind
body: <p>My goal is to generate the aspx code of a page in the form of string.I am calling the below codebehind code through asynchronous request in javascript and i am getting the response back through Response.Write</p>
  
  <pre><code>        string html = string.Empty;
          using (var memoryStream = new MemoryStream())
          {
              using (var streamWriter = new StreamWriter(memoryStream))
              {
                  var htmlWriter = new HtmlTextWriter(streamWriter);
                  base.Render(htmlWriter);
                  htmlWriter.Flush();
                  memoryStream.Position = 0;
                  using (var streamReader = new StreamReader(memoryStream))
                  {
                      html = streamReader.ReadToEnd();
                      streamReader.Close();
                  }
              }
          }
          Response.Write(html);
          Response.End();
  </code></pre>
  
  <p>I want to ask that is the above code is memory efficient, I am thinking of "yield" to use as it evaluates lazily.Can u suggest on memory efficency of above code.</p>
