1. Mode.csl:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace ProgressBar.Models
{
    public class User
    {
        public int Id { get; set; }

        public string Name { get; set; }

        public DateTime JoinDate { get; set; }

        public int ContractYears { get; set; }
    }
}

2. HomeController.cs:

    public class HomeController : Controller
    {
        //
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult GetNowProgressBarShow()
        {
            User user = new User() { Id = 1, Name = "tianqy", JoinDate = new DateTime(2014, 1, 1), ContractYears = 1 };
            //判断合同是否到期
            int expire = DateTime.Compare(DateTime.Now, user.JoinDate.AddYears(user.ContractYears));
            if (expire <= 0) //未到期
            {
                //计算已过时间占得百分比
                var pastDays = (DateTime.Now.Subtract(user.JoinDate)).TotalDays;
                var totalDays = (user.JoinDate.AddYears(user.ContractYears).Subtract(user.JoinDate)).TotalDays;
                var pastPercentage = (pastDays / totalDays) * 100;
                //装载、返回Json数据
                var data = new { IsExpire = false, PastPercentage = pastPercentage };
                return Json(data,JsonRequestBehavior.AllowGet);
            }
            else //已过期
            {
                var data = new { IsExpire = true, PastPercentage = 100 };
                return Json(data, JsonRequestBehavior.AllowGet);
            }
        }
    }
