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

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.
