如何从JSON字符串中删除转义字符

Question

我使用以下返回的JSON字符串调用了REST API：

"{\"profile\":[{\"name\":\"city\",\"rowCount\":1,\"location\": ............

在反序列化之前，我尝试使用以下代码删除转义符：

 jsonString = jsonString.Replace(@"\", " ");

但是，当我反序列化它时，它会抛出一个input string was not in a correct format：

SearchRootObject obj = JsonConvert.DeserializeObject<SearchRootObject>(jsonString);

以下是完整的代码：

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;
    }

在切换到使用JavaScriptSerializer()反序列化 JSON string 后，我意识到我的对象中有一个int类型property用于 JSON 字符串中的十进制值。我更改int为double，这解决了我的问题。和JsonConvert.DeserializeObject<>都JavaScriptSerializer()处理转义字符。无需删除转义字符。我替换了以下代码：

jsonString = jsonString.Replace(@"\", " ");        
SearchRootObject obj = JsonConvert.DeserializeObject<SearchRootObject>(jsonString);
return obj;

和：

return new JavaScriptSerializer().Deserialize<SearchObj.RootObject>(jsonString);
