c# windows phone json字符编码

Question

我正在向我的服务器发送 json 数据，但编码特殊字符的小问题不起作用：

word的详细信息，服务器收据中的日志为dxc3xa9tails

而不是这样：d\xc3\xa9tails

我在发送数据之前记录数据时的输出甚至没有被编码，因为我看到了“详细信息”。

你知道可能是什么问题吗？谢谢

public void Event(String eventType, Dictionary<String, String> dataOptionnal)

            listener.OnPostExecute(e.Message, HttpStatusCode.NotFound , MobilAirTools.GetDomainName(url));

    }
}

MobilAirTools 方法：

public static String JsonToString(JObject jobject)
    {
        return JsonConvert.SerializeObject(jobject, Formatting.None);
    }
    public static String DictToNameValuePair(Dictionary<String, String> dict)
    {
        StringBuilder data = new StringBuilder();

        foreach (string key in dict.Keys)
        {
            data.Append(key + "=" + dict[key] + "&");
        }
        data.Length--;
        return data.ToString();

    }

问题出在 MARequest 类中：

postStream.Write(byteArray, 0, data.Length);

//替换为

postStream.Write(byteArray, 0, byteArray.Length);

现在开始工作了！
