解決：MVC對象轉json包含\r \n

項目中對象轉json字符串時，如下：
JsonSerializerSettings jsetting = new JsonSerializerSettings(); jsetting.DefaultValueHandling = DefaultValueHandling.Ignore; return JsonConvert.SerializeObject(resultMoldels, Formatting.Indented, jsetting);
發現返回的字符串中包含換行符 \r\n

"{\r\n \"result\": true,\r\n \"msg\": \"OK\",\r\n \"data\": [\r\n \"success\",\r\n \"123456789\",\r\n \"987654321\"\r\n ]\r\n}"

解決方法：
Formatting.Indented 修改成 Formatting.None
