Question

我的目标是能够接受任何输入并将数据添加到现有数据库中。如何在不特别声明反序列化器的情况下访问“名称”和“用户编号”属性（因为该类将根据查询而改变）？

{  
   "MessageType":"Sql",
   "SqlCommandString":"select [name],[usernum] from x.dbo.y",
   "DbReply":[  
      {  
         "name":"xx",
         "usernum":22
      },
      {  
         "name":"yy",
         "usernum":23
      }
   ]
}

C＃反序列化JSON：

public class SqlReply
{
    public string MessageType { get; set; }
    public string SqlCommandString { get; set; }
    public List<object> DbReply { get; set; }
}

Answer 1

您可以使用Json.Linq：

var json = @"{  
   ""MessageType"":""Sql"",
   ""SqlCommandString"":""select [name],[usernum] from x.dbo.y"",
   ""DbReply"":[  
      {  
         ""name"":""xx"",
         ""usernum"":22
      },
      {  
         ""name"":""yy"",
         ""usernum"":23
      }
   ]
}";

var sql = JToken.Parse(json);
var replies = sql["DbReply"]
    .Select(x => new
    {
        Name = (string)x["name"],
        UserNum = (int)x["usernum"],
    });

Answer 2

在这里，您可以使用JavaScriptSerializer中定义的System.Web.Extensions.dll类来执行此操作。您可以将JSON数据反序列化为dynamic对象：

var serializer = new JavaScriptSerializer();
dynamic obj = serializer.Deserialize(json, typeof(object));
foreach (var reply in obj["DbReply"])
{
    string name = reply["name"];
    int usernum = reply["usernum"];
}

或进入DbReply：

var serializer = new JavaScriptSerializer();
SqlReply obj = serializer.Deserialize(json, typeof(SqlReply)) as SqlReply;
foreach (dynamic reply in obj.DbReply)
{
    string name = reply["name"];
    int usernum = reply["usernum"];
}

感谢评论中的@stuartd建议，我将使用parse然后手动解析字符串
