之前寫過一篇關於C#獲取到農曆相關的，今天又研究了一下，再寫一篇

星座類：

using System;

namespace LingbugUtils.Models
{
    public class ConstellationModel
    {
        public ConstellationModel(string name, string beginStr, string endStr)
        {
            this.Name = name + "座";
            this.Begin = Convert.ToDateTime(Convert.ToDateTime(beginStr).ToString("yyyy-MM-dd 00:00:00.000"));
            this.End = Convert.ToDateTime(Convert.ToDateTime(endStr).ToString("yyyy-MM-dd 23:59:59.999"));
        }

        public string Name { get; set; }

        public DateTime Begin { get; set; }

        public DateTime End { get; set; }
    }
}
