c#: initialize a DateTime array
I am a bit lost on how to do 开发者_StackOverflow社区this. I know how to initialize an array with values at the time of declaration. But how would I do it with a DateTime type array since it takes multiple arguments to create a date?
You mean like this?
DateTime[] dateTimes = new DateTime[]
{
new DateTime(2010, 10, 1),
new DateTime(2010, 10, 2),
// etc
};
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);
If you want to build an array for time span between two dates you could do something like this:
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;
}
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
}
DateTime [] "name_of_array"=new Date[int lenght_of_the_array]; //this is the array DateTime
And then when you assign the value in each position of the array:
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
