How to remove escape characters from a JSON String - c#-4.0

Question

I called a REST API with the following JSON string returned:
"{\"profile\":[{\"name\":\"city\",\"rowCount\":1,\"location\": ............
I tried to remove escape character with the following code before I deserialize it:
jsonString = jsonString.Replace(#"\", " ");
But then when I deserialize it, it throws an input string was not in a correct format:
SearchRootObject obj = JsonConvert.DeserializeObject<SearchRootObject>(jsonString);
The following is the complete code:
public static SearchRootObject obj()
{
String url = Glare.searchUrl;
string jsonString = "";
// Create the web request
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
// Get response
var response = request.GetResponse();
Stream receiveStream = response.GetResponseStream();
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);
jsonString = jsonString + readStream.ReadToEnd();
jsonString = jsonString.Replace(#"\", " ");
// A C# object representation of deserialized JSON string
SearchRootObject obj = JsonConvert.DeserializeObject<SearchRootObject>(jsonString);
return obj;
}

After switching to use JavaScriptSerializer() to deserialize JSON string , I realized that I have an int type property in my object for a decimal value in the JSON string. I changed int to double, and this solved my problem. Both JsonConvert.DeserializeObject<> and JavaScriptSerializer() handle escape character. There's no need to remove escape character.
I replaced the following codes:
jsonString = jsonString.Replace(#"\", " ");
SearchRootObject obj = JsonConvert.DeserializeObject<SearchRootObject>(jsonString);
return obj;
With:
return new JavaScriptSerializer().Deserialize<SearchObj.RootObject>(jsonString);
