推荐答案

public class SubDetail
{
    public string Sub1 { get; set; }
    public string Sub2 { get; set; }
    public string Sub3 { get; set; }
}

public class RootObject
{
    public string No { get; set; }
    public int Age { get; set; }
    public List<SubDetail> SubDetail { get; set; }
}
class Program
{
    static void Main(string[] args)
    {
        RootObject obj = new RootObject();
        obj.No = "1";
        obj.Age = 7;

        int lenght = 3;
        int counter = 0;

        for(int i=0; i<lenght; i++)
        {
            SubDetail detail = new SubDetail();
            detail.Sub1 = (counter + 1).ToString();
            detail.Sub2 = (counter + 1).ToString();
            detail.Sub3 = (counter + 1).ToString();

            if (obj.SubDetail == null)
                obj.SubDetail = new List<SubDetail>();

            obj.SubDetail.Add(detail);
        }

        var jsonString = JsonConvert.SerializeObject(obj);

        Console.WriteLine(jsonString);

    }
}

这是您案件的完整示例.另外，您还需要将Newtonsoft.Json dll添加到您的项目中，您可以在Package Manager控制台中使用此行来完成它.

Here is full example for your case. Also you need to add Newtonsoft.Json dll to your project you can do it with this line in the Package Manager Console.

Install-Package Newtonsoft.Json -Version 7.0.1
