需要的using

復(fù)制代碼代碼如下:

using System;  

using System.Collections.Generic;  

using System.Web;  

using System.Text;  

using System.Globalization;

調(diào)用：

復(fù)制代碼代碼如下:

CountryDate cd = new CountryDate();  

string ChineseTimeNow = cd.GetChineseDate(DateTime.Now);//農(nóng)歷日期  

string ForignTimeNow = DateTime.Now.GetDateTimeFormats('D')[0].ToString();//公歷日期

下面有一個測試的效果：
