以上是Json多层数组的数据

            request.ContentType = "application/json;charset=UTF-8"; //识别编码格式UTF-8
            HttpWebResponse response = (HttpWebResponse)request.GetResponse(); //响应,强制转换
            Stream myResponseStream = response.GetResponseStream();   //获取流,需要引用命名空间IO
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);  //流读取器,观察者模式

textBox1.Text = myStreamReader.ReadToEnd();   //读取放到text里(我想让JSON数组里的数据显示在Listview列表里)



  myStreamReader.Close();     //关闭
            myStreamReader.Dispose();   //释放
            myResponseStream.Close();   //关闭流
            myResponseStream.Dispose(); //释放流

?





以下代码编译不成功,不知道是不是要在类单元里定义实体类


1、使用Newtonsoft.Json的DeserializeObject方法将json字符串反序列化为对象：
string json = "";  //json字符串
var result = JsonConvert.DeserializeObject<List<Dictionary<string,string>>>(json);

2、使用foreach循环遍历每一层的[]中括号内的数据，将其加入到字符串中：
string str = "";
foreach (var item1 in result)
{
    foreach (var item2 in item1)
    {
        str +=item2.Key +":"+item2.Value;
    }
}

3、将获取到的字符串赋值给text控件：
text.Text = str;

使用Newtonsoft.Json的DeserializeObject方法将json字符串反序列化为对象)有没有大神指点指点?一起交流互相学习.

解析JSon的关键在于定义出对应的对象，然后直接反序列化就行了。

而这个可以用我的工具直接根据Json串生成对应的类

我想问下转换C#实体类,那么网站接口每天的JSON数据都不一样,不就是要每天都要在C#实体类里修改后编译一次程序才能访问该网站接口的JSON数据?能否让程序接收JSON每天不一样的数据?

每天的都不一样应该是有规律的吧，或者是你写一个全部参数的，不够的不填就行了。如果真是必须变化，而且每天的差别特别大，那就使用动态类型
