C#中比较两个日期大小的方法
/// <summary> /// 比较两个日期大小 /// </summary> /// <param name="dateStr1">日期1</param> /// <param name="dateStr2">日期2</param> /// <param name="msg">返回信息</param> public void CompanyDate(string dateStr1, string dateStr2,ref string msg) { //将日期字符串转换为日期对象 DateTime t1 = Convert.ToDateTime(dateStr1); DateTime t2 = Convert.ToDateTime(dateStr2); //通过DateTIme.Compare()进行比较（） int compNum = DateTime.Compare(t1, t2); //t1> t2 if (compNum > 0) { msg = "t1:(" + dateStr1 + ")大于" + "t2(" + dateStr2 + ")"; } //t1= t2 if (compNum == 0) { msg = "t1:(" + dateStr1 + ")等于" + "t2(" + dateStr2 + ")"; } //t1< t2 if (compNum < 0) { msg = "t1:(" + dateStr1 + ")小于" + "t2(" + dateStr2 + ")"; } }
调用的代码
public ActionResult Index() { //t1< t2 string msg1 = string.Empty; string date1 = "2018-07-25"; string date2 = "2018-07-27"; CompanyDate(date1,date2,ref msg1); //t1> t2 string msg2 = string.Empty; string date3 = "2018-07-27"; string date4 = "2018-07-25"; CompanyDate(date3, date4, ref msg2); return View(); }
整体demo源码
public class TestController : Controller { // GET: Test public ActionResult Index() { //t1< t2 string msg1 = string.Empty; string date1 = "2018-07-25"; string date2 = "2018-07-27"; CompanyDate(date1,date2,ref msg1); //t1> t2 string msg2 = string.Empty; string date3 = "2018-07-27"; string date4 = "2018-07-25"; CompanyDate(date3, date4, ref msg2); return View(); } /// <summary> /// 比较两个日期大小 /// </summary> /// <param name="dateStr1">日期1</param> /// <param name="dateStr2">日期2</param> /// <param name="msg">返回信息</param> public void CompanyDate(string dateStr1, string dateStr2,ref string msg) { //将日期字符串转换为日期对象 DateTime t1 = Convert.ToDateTime(dateStr1); DateTime t2 = Convert.ToDateTime(dateStr2); //通过DateTIme.Compare()进行比较（） int compNum = DateTime.Compare(t1, t2); //t1> t2 if (compNum > 0) { msg = "t1:(" + dateStr1 + ")大于" + "t2(" + dateStr2 + ")"; } //t1= t2 if (compNum == 0) { msg = "t1:(" + dateStr1 + ")等于" + "t2(" + dateStr2 + ")"; } //t1< t2 if (compNum < 0) { msg = "t1:(" + dateStr1 + ")小于" + "t2(" + dateStr2 + ")"; } } }
