檢查年份是否爲閏年

Question

<script Language="c#" runat="server"> 
    void Page_Load() 
    { 
    int currentYear = DateTime.Now.Year(); 

    if (currentYear % 400 == 0) { 
    Message2.Text = ("This is a leap year"); 
    } 
    else { 
    Message2.Text = ("This is not a leap year"); 
    } 

} 

目前我遇到RunTime錯誤。我的目標是測試使用DateTime.Now.Year（）的當前年份是否爲閏年。我認爲問題是我沒有正確地將年份轉換爲整數？請指教。

Answer 1

年屬性，以便犯規需要括號...

Answer 2

你可以用DateTime.IsLeapYear()：

if (DateTime.IsLeapYear(year)) 
{ 
    //do stuff 
} 

Answer 3

int x= int.Parse(Console.ReadLine()); 

    if((x%400==0)||(x%100==0)||(x%4==0)) 
    { 
     Console.WriteLine(" \n\n\n The year is a leap year ...!"); 
    } 
    else 
    { 
      Console.WriteLine("\n\n\n The year is not a leap year"); 
    }
