使用Newtonsoft.Json反序列化收到的字串为JObject或其它支持的数据模型,有时错误,提示如下:
Bad JSON escape sequence: \c. Path 'idno', line 5, position 34.
甚纳闷之。遂搜索资料,略有小获,其非法分界符所致。合法的分隔符为:
以此为依据,对字串做正则替换,问题解决,录代码以记之。
static void Main(string[] args) { string s = @" { ""name"": ""王艳"", ""sex"": ""女"", ""idno"": ""34*****\c0"", ""addr"": ""安徽省"", ""telephone"": ""no number"", ""thumbnail"": ""e:\docs\person\thumbnail\wy.jpg"", ""Age"": 27, ""DeptName"": ""姚江\R中心"" } "; //\加bfrnt\/'"为合法分隔符,其它不是,替换 string pattern = @"(\\[^bfrnt\\/'\""])"; s = Regex.Replace(s, pattern, "\\$1"); var jo = JsonConvert.DeserializeObject<JObject>(s); Console.WriteLine(jo.ToString()); Console.ReadLine(); }
结果如图:
