json字符串中包含"\"时，如何解析这个json字符串

/// <summary>
    /// 处理json字符串中的特殊字符
    /// </summary>
    /// <param name="ors"></param>
    /// <returns></returns>
    public static String StringDanYinToJSON(String ors)
    {
        ors = ors == null ? "" : ors;
        StringBuilder buffer = new StringBuilder(ors);
        int i = 0;
        while (i < buffer.Length)
        {
            if (buffer[i] == ‘\‘‘ || buffer[i] == ‘\\‘)
            {
                buffer.Insert(i, ‘\\‘);
                i += 2;
            }
            else
            {
                i++;
            }
        }
        return buffer.ToString();
    }

用上述代码在后台处理下就可以了
