C#获取到农历相关（带星座）（关于更多请参考我之前的一篇星座博客以及官网Api）

之前写过一篇关于C#获取到农历相关的，今天又研究了一下，再写一篇

星座类：

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; }
    }
}
