# DateTimeOffset.ToUniversalTime Metodo

## Definizione

Converte l'oggetto DateTimeOffset corrente in un valore DateTimeOffset che rappresenta l'ora UTC (Coordinated Universal Time).Converts the current DateTimeOffset object to a DateTimeOffset value that represents the Coordinated Universal Time (UTC).

``````public:
DateTimeOffset ToUniversalTime();``````
``public DateTimeOffset ToUniversalTime ();``
``member this.ToUniversalTime : unit -> DateTimeOffset``
``Public Function ToUniversalTime () As DateTimeOffset``

#### Restituisce

Oggetto che rappresenta la data e l'ora dell'oggetto DateTimeOffset corrente convertite nell'ora UTC (Coordinated Universal Time).An object that represents the date and time of the current DateTimeOffset object converted to Coordinated Universal Time (UTC).

## Esempi

Nell'esempio seguente viene chiamato il metodo ToUniversalTime per convertire un'ora locale e diverse altre volte nell'ora UTC (Coordinated Universal Time).The following example calls the ToUniversalTime method to convert a local time and several other times to Coordinated Universal Time (UTC).

``````DateTimeOffset localTime, otherTime, universalTime;

// Define local time in local time zone
localTime = new DateTimeOffset(new DateTime(2007, 6, 15, 12, 0, 0));
Console.WriteLine("Local time: {0}", localTime);
Console.WriteLine();

// Convert local time to offset 0 and assign to otherTime
otherTime = localTime.ToOffset(TimeSpan.Zero);
Console.WriteLine("Other time: {0}", otherTime);
Console.WriteLine("{0} = {1}: {2}",
localTime, otherTime,
localTime.Equals(otherTime));
Console.WriteLine("{0} exactly equals {1}: {2}",
localTime, otherTime,
localTime.EqualsExact(otherTime));
Console.WriteLine();

// Convert other time to UTC
universalTime = localTime.ToUniversalTime();
Console.WriteLine("Universal time: {0}", universalTime);
Console.WriteLine("{0} = {1}: {2}",
otherTime, universalTime,
universalTime.Equals(otherTime));
Console.WriteLine("{0} exactly equals {1}: {2}",
otherTime, universalTime,
universalTime.EqualsExact(otherTime));
Console.WriteLine();
// The example produces the following output to the console:
//    Local time: 6/15/2007 12:00:00 PM -07:00
//
//    Other time: 6/15/2007 7:00:00 PM +00:00
//    6/15/2007 12:00:00 PM -07:00 = 6/15/2007 7:00:00 PM +00:00: True
//    6/15/2007 12:00:00 PM -07:00 exactly equals 6/15/2007 7:00:00 PM +00:00: False
//
//    Universal time: 6/15/2007 7:00:00 PM +00:00
//    6/15/2007 7:00:00 PM +00:00 = 6/15/2007 7:00:00 PM +00:00: True
//    6/15/2007 7:00:00 PM +00:00 exactly equals 6/15/2007 7:00:00 PM +00:00: True

## Commenti

Questo metodo restituisce un oggetto DateTimeOffset la cui proprietà Offset è impostata su zero.This method returns a DateTimeOffset object whose Offset property is set to zero.

Il valore dell'oggetto DateTimeOffset corrente e il valore dell'oggetto DateTimeOffset restituito dalla chiamata al metodo rappresentano lo stesso punto nel tempo.Both the value of the current DateTimeOffset object and the value of the DateTimeOffset object returned by the method call represent the same point in time. Ovvero, se entrambi vengono passati al metodo DateTimeOffset.Equals(DateTimeOffset, DateTimeOffset), il metodo restituirà `true`.That is, if both are passed to the DateTimeOffset.Equals(DateTimeOffset, DateTimeOffset) method, the method will return `true`.
