c＃：初始化一個DateTime數組

Question

嘿傢伙，我有點失去了如何做到這一點。我知道如何在聲明時使用值初始化數組，但是如何使用DateTime類型的數組來完成它，因爲它需要多個參數才能創建日期？

Answer 1

您的意思是這樣的？

DateTime[] dateTimes = new DateTime[] 
{ 
    new DateTime(2010, 10, 1), 
    new DateTime(2010, 10, 2), 
    // etc 
}; 

Answer 2

DateTime [] startDate = new DateTime[5]; 
     startDate[0] = new DateTime(11, 11, 10); 
     startDate[1] = new DateTime(11, 11, 10); 
     startDate[2] = new DateTime(11, 11, 10); 
     startDate[3] = new DateTime(11, 11, 10); 
     startDate[4] = new DateTime(11, 11, 10); 

Answer 3

DateTime [] "name_of_array"=new Date[int lenght_of_the_array]; //this is the array DateTime 

然後當你在陣列中的每個位置分配值：

DateTime "name_of_each_element_of_the_array"= new DateTime(int value_of_year,int value_of_month, int value_of_day);//this is each element that is added in each position of the array 

Answer 4

For example, i want to add a DateTime array of 4 elements:      DateTime[] myarray=new DateTime [4]; //the array is created 
int year, month, day;    //variables of date are created    
for(int i=0; i<myarray.length;i++) 
{ 
    Console.WriteLine("Day"); 
    day=Convert.ToInt32(Console.ReadLine()); 
    Console.WriteLine("Month"); 
    month=Convert.ToInt32(Console.ReadLine()); 
    Console.WriteLine("Year"); 
    year=Convert.ToInt32(Console.ReadLine()); 

    DateTime date =new DateTime(year,month,day); //here is created the object DateTime, that contains day, month and year of a date 

myarray[i]=date; //and then we set each date in each position of the array 
} 

Answer 5

如果你想建立兩個日期之間的時間跨度數組你可以這樣做：

 timeEndDate = timeStartDate.AddYears(1); // or .AddMonts etc.. 
     rangeTimeSpan = timeEndDate.Subtract(timeStartDate); //declared prior as TimeSpan object 
     rangeTimeArray = new DateTime[rangeTimeSpan.Days]; //declared prior as DateTime[] 

     for (int i = 0; i < rangeTimeSpan.Days; i++) 
     { 
      timeStartDate = timeStartDate.AddDays(1); 
      rangeTimeArray[i] = timeStartDate; 
     }
