mygeneratedresponse.Skip(1).ToList();
它起作用了。但是有更好的解决方案吗？我不确定这是否是您想要的，但是，请按照一种方法获得重复值，并使用linq对其进行分组 您只需创建一个consoleapp并向其中添加newtonsoft.json，即可运行下面的代码
class Program
{
static string pathA = "<place-your-first-json-location-here>"; //ex: c:\test\test.json
static void Main(string[] args)
{
var json = JsonConvert.DeserializeObject<Test>(File.ReadAllText(pathA));
var filteredByName = json.Response.GroupBy(g => g.Name).OrderBy(o => o.Key).ToList();
foreach (var item in filteredByName)
{
Console.WriteLine($"Name: {item.Key} Qty response: {item.Count()}" );
}
}
}
以下代码将生成您的预期输出： 此代码也放在.NETFIDLE上
使用系统；
使用System.Collections.Generic；
使用Newtonsoft.Json；
使用System.Linq；
