当我读json文件时出现两个错误。



我的代码是

Hi,
I got two errors When I read json file.

My code is

public class JsonData
   {
       public string Title { get; set; }
       public string Description { get; set; }
       public string Link { get; set; }
      
   }

using (StreamReader r = new StreamReader(filename))
                   {
                       string json = r.ReadToEnd();
                       List<JsonData> datas = Newtonsoft.Json.JsonConvert.DeserializeObject<List<JsonData>>(json);

                       var data = from c in datas
                           group c by
                               new
                               {
                                   c.Title,
                                   c.Link,
                                   c.Description

                               }
                           into gac
                           select new JsonData()
                           {
                               Title = gac.Key.Title,
                               Link = gac.Key.Link,
                               Description = gac.Key.Description

                           };
                       foreach (var jsonData in data)
                       {
                           Console.WriteLine("Title:" + jsonData.Title);
                       }

                   }

我收到了这两个错误

I got these two errors

After parsing a value an unexpected character was encountered: T. Path '[644].Description', line 5160, position 44.

Bad JSON escape sequence: \S. Path '[147].Description', line 1184, position 247.

请帮帮我。

谢谢。

Please help me.
Thanks.

推荐答案

你能在这里发布你的json字符串吗？通过阅读错误，我建议您在反序列化之前删除所有\字符。



尝试

Hi,

Can you post your json string here ? By reading at the error, I would suggest you remove all the "\" character before you deserialize it.

Try

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

在反序列化过程之前。



问候，

before the deserialization process.

您好，



尝试使用自定义序列化功能..



以下是用于反序列化的模板类

Hi,

Try to use a custom serialize function ..

Below is the Template class used for Deserialize

<pre lang="cs">public static T Deserialize&lt;T&gt;(string json) {
           var obj = Activator.CreateInstance&lt;T&gt;();
           using (var memoryStream = new MemoryStream(Encoding.Unicode.GetBytes(json))) {
               var serializer = new DataContractJsonSerializer(obj.GetType());
               obj = (T) serializer.ReadObject(memoryStream);
               return obj;
           }
       }</pre>

相应的模板功能可以如下所示使用...

The respective template function can be used as shown below...

StudentList = Deserialise<list>< Student >> (JsonString);

</list>

hi，

我发现了问题和解决方案。 />

I found the problem and soluation.

After parsing a value an unexpected character was encountered

Bad JSON escape sequence: \S

来自\和\特殊字符的这两个错误。



我这样替换了

these two errors from \ and \" special characters.

I replaced like this

json = json.Replace(@"\""", "s");

之后

after that

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

如果你再次替换第一个\然后\在json字符串中你就会出错。

if you replace first \ then \" in a json string again you got error.
