            "batchSignupSum": "0"
        }
    ]
}

2、我用[size=1.4em]Json生成类在线生成工具生成了一个类如下：

[C#] 纯文本查看 复制代码

using System;  
  
namespace MorePush  
{  
  
    public class Datum  
    {  
        public string id { get; set; }  
        public string batchid { get; set; }  
        public string batchwriteid { get; set; }  
        public string batchname { get; set; }  
        public string systemname { get; set; }  
        public string projectname { get; set; }  
        public string batchaddress { get; set; }  
        public string batchCreated_at { get; set; }  
        public string batchSignupSum { get; set; }  
    }  
  
    public class ListViewInfo  
    {  
        public string total { get; set; }  
        public IList<Datum> data { get; set; }  
    }  
  
}  

3、我写了这样一段代码：

[C#] 纯文本查看 复制代码

List<ListViewInfo> jsonlist = (List<ListViewInfo>)HttpHelper.JsonToObject<List<ListViewInfo>>(resultJson.ToString());

但在测试过程中，发现jsonlist仍然为0，这是什么情况啊？是不是我的语句哪里写错了？

站长苏飞

你的Json是一个对象，而你写成了一个集合，能生成才怪呢

[C#] 纯文本查看 复制代码

         ListViewInfo jsonlist = (ListViewInfo)HttpHelper.JsonToObject<ListViewInfo>(sb.ToString());

应该是这样写

嗯 是啊。你搞错对象了。
