.NET Framework 4.5

Other Versions

Initializes a new instance of the DateTime structure to the specified year, month, and day.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

C++

public DateTime(
	int year,
	int month,
	int day
)

Parameters

year: Type: System.Int32
The year (1 through 9999).

month: Type: System.Int32
The month (1 through 12).

day: Type: System.Int32
The day (1 through the number of days in month).

Exceptions

Exception	Condition
ArgumentOutOfRangeException	year is less than 1 or greater than 9999. -or- month is less than 1 or greater than 12. -or- day is less than 1 or greater than the number of days in month.

Exception

Condition

ArgumentOutOfRangeException

year is less than 1 or greater than 9999.

-or-

month is less than 1 or greater than 12.

-or-

day is less than 1 or greater than the number of days in month.

Remarks

This constructor interprets year, month, and day as a year, month, and day in the Gregorian calendar. To instantiate a DateTime value by using the year, month, and day in another calendar, call the DateTime(Int32, Int32, Int32, Calendar) constructor.

The time of day for the resulting DateTime is midnight (00:00:00). The Kind property is initialized to DateTimeKind.Unspecified.

Examples

The following example uses the DateTime(Int32, Int32, Int32) constructor to instantiate a DateTime value. The example also illustrates that this overload creates a DateTime value whose time component equals midnight (or 0:00).

DateTime date1 = new DateTime(2010, 8, 18);
Console.WriteLine(date1.ToString());
// The example displays the following output: 
//      8/18/2010 12:00:00 AM
