some problems with converting from StringBuilder to string

Question

I read response from google weather like this

using (StreamReader streamreader = new StreamReader(resp.GetResponseStream(), Encoding.GetEncoding(1251)))
        {
            sb.AppendLine(streamreader.ReadToEnd());
            sb.Remove(0, 21);

In debugger string looks like

<xml_api_reply version="1">

but when I convert StringBuilder to string I've got

  <xml_api_reply version=\"1\">

It adds \ before every ". What's the problem?

you see the "\" in the debugger when you analyze the string? Or you output the string and it has the \ in the actual output? — James Michael Hare, May 03 '12 at 22:01

If you see the slashes in the debugger, it's not a problem: it's normal.

The QuickWatch/Watch window will add the extra \ in. If you view it in the Text Visualizer, you will not see them:

QuickWatch:
"{  \"data\": {  \"urls\": [  {\"url\": \"domain/path1\"}  ,{\"url\": 
    \"domain/path2\"}  ]  }}"
Visualizer (the actual output):
{  "data": {  "urls": [  {"url": "domain/path1"}  ,{"url": "domain/path2"}  ]  }}
The \ indicates that the quotes have been escaped and will be included in the final string as you're expecting them to be. I.e. there's nothing wrong with your output.

hm...So it doesn't cause `ArgumentException(Illegal characters in path)`...Strange. — Артём Царионов, May 03 '12 at 22:12
