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

Syntax

Visual Basic (Declaration)

Public Sub New ( _
    year As Integer, _
    month As Integer, _
    day As Integer _
)

Visual Basic (Usage)

Dim year As Integer
Dim month As Integer
Dim day As Integer

Dim instance As New DateTime(year, month, _
    day)

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

Visual C++

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

JScript

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

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.
ArgumentException	The specified parameters evaluate to less than DateTime..::.MinValue or more than DateTime..::.MaxValue.

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.

ArgumentException

The specified parameters evaluate to less than DateTime..::.MinValue or more than DateTime..::.MaxValue.

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).

Visual Basic

Dim date1 As New Date(2010, 8, 18)
Console.WriteLine(date1.ToString())
' The example displays the following output:
'      8/18/2010 12:00:00 AM

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