DateTimeOffset.Implicit(DateTime to DateTimeOffset) Operator

Definition

Defines an implicit conversion of a DateTime object to a DateTimeOffset object.

public:
 static operator DateTimeOffset(DateTime dateTime);
public static implicit operator DateTimeOffset (DateTime dateTime);
static member op_Implicit : DateTime -> DateTimeOffset
Public Shared Widening Operator CType (dateTime As DateTime) As DateTimeOffset

Parameters

dateTime
DateTime

The object to convert.

Returns

DateTimeOffset

The converted object.

Exceptions

The Coordinated Universal Time (UTC) date and time that results from applying the offset is earlier than MinValue.

-or-

The UTC date and time that results from applying the offset is later than MaxValue.

Remarks

The Implicit method enables the compiler to automatically convert a DateTime object to a DateTimeOffset object without an explicit casting operator (in C#) or a call to a conversion function (in Visual Basic). It defines a widening conversion that does not involve data loss and does not throw an OverflowException. The Implicit method makes code such as the following possible:

DateTimeOffset timeWithOffset;
timeWithOffset = new DateTime(2008, 7, 3, 18, 45, 0);
Console.WriteLine(timeWithOffset.ToString());

timeWithOffset = DateTime.UtcNow;
Console.WriteLine(timeWithOffset.ToString());

timeWithOffset = DateTime.SpecifyKind(DateTime.Now,
                                      DateTimeKind.Unspecified);
Console.WriteLine(timeWithOffset.ToString());

timeWithOffset = new DateTime(2008, 7, 1, 2, 30, 0) +
                       new TimeSpan(1, 0, 0, 0);
Console.WriteLine(timeWithOffset.ToString());

timeWithOffset = new DateTime(2008, 1, 1, 2, 30, 0);
Console.WriteLine(timeWithOffset.ToString());

//       1/1/2008 2:30:00 AM -08:00

This method is equivalent to the DateTimeOffset constructor. The offset of the resulting DateTimeOffset object depends on the value of the DateTime.Kind property of the dateTime parameter:

The equivalent method for this operator is DateTimeOffset.DateTimeOffset(DateTime)
