C#-从JSON反序列化，结果始终为空对象

我尝试从JSON字符串中读取c#中的对象，但结果总是空对象，没有任何异常，但我没有看到错误

我从Web服务获得的JSON字符串是

{  
   "CustomUserFields":{
   },
   "CustomApplicationFields":{    
   },
   "Attachments":[    
   ],
   "Tags":[    
   ],
   "HasModifyEntriesAccess":true,
   "HasViewEntryContentsAccess":true,
   "CommentPrompts":{  
      "AskForCommentOnViewPassword":false,
      "AskForCommentOnViewOffline":false,
      "AskForCommentOnModifyEntries":false,
      "AskForCommentOnMoveEntries":false,
      "AskForCommentOnMoveFolders":false,
      "AskForCommentOnModifyFolders":false
   },
   "Id":"c51ca807-9e01-4652-95d0-645a0914b1ba",
   "Name":"SecondOne",
   "Username":"Second@test.domain",
   "Password":null,
   "Url":"",
   "Notes":"Bla Bla Bla",
   "GroupId":"1182570d-d22d-4f2a-babb-3dab4ff48852",
   "Created":"2018-02-27T14:39:15+01:00",
   "Modified":"2018-02-27T14:39:15+01:00",
   "Expires":null,
   "UsageComment":null
}

我的代码如下所示

DataContractJsonSerializer serF = new DataContractJsonSerializer(typeof(Credential));
Credential cred1 = new Credential();
MemoryStream msF = new MemoryStream(Encoding.UTF8.GetBytes(response2.Content));
cred1 = serF.ReadObject(msF) as Credential;
msF.Close();

[Serializable, XmlRoot("Credential"), DataContract(Name = "Credential")]
public class Credential
{
    [DataMember]
    public Guid id = Guid.Empty;
    [DataMember]
    public Guid groupid = Guid.Empty;
    [DataMember]
    public string name = String.Empty;
}

我从类中删除了一些属性以简化代码的读取-但这没有什么区别

凭证对象cred1始终具有Json中的空属性

C#类（通过以下方式自动生成） :

公共类CustomUserFields
{
}
公共类CustomApplicationFields
{
}
公共类注释提示
{
公共bool AskForCommentOnViewPassword{get；set；}
公共bool AskForCommentOnViewOffline{get；set；}
公共bool askforcommentomodifyentries{get；set；}
公共bool AskForCommentOnMoveEntries{get；set；}
public bool AskForCommentOnMoveFolders{get；set；}
public bool askforcommentomodifyfolders{get；set；}
}
公共类根对象

}

查看区分大小写

现在不确定，反序列化是否区分大小写？Bcs。您使用了小写的属性&JSON作为CamelCase。您使用了

response2

，这不可能从您的代码中看到定义，但这不应该是一个请求对象吗？还可以使用

使用

流块来确保所有内容都被关闭/处置，这样，如果您不小心，就不会导致内存泄漏
