Definition

Namespace:

System

Assemblys:

netstandard.dll, System.Runtime.dll

Quelle:

DateTimeOffset.cs

Konvertiert das aktuelle DateTimeOffset Objekt in einen DateTimeOffset Wert, der die koordinierte Weltzeit (COORDINATED Universal Time, UTC) darstellt.

public:
 DateTimeOffset ToUniversalTime();

public DateTimeOffset ToUniversalTime();

member this.ToUniversalTime : unit -> DateTimeOffset

Public Function ToUniversalTime () As DateTimeOffset

Gibt zurück

DateTimeOffset

Ein Objekt, das das Datum und die Uhrzeit des aktuellen DateTimeOffset Objekts darstellt, das in koordinierte Weltzeit (COORDINATED Universal Time, UTC) konvertiert wird.

Beispiele

Im folgenden Beispiel wird die ToUniversalTime Methode aufgerufen, um eine Ortszeit und mehrmals in koordinierte Weltzeit (Coordinated Universal Time, UTC) zu konvertieren.

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:

// Convert local time to offset 0 and assign to otherTime
let otherTime = localTime.ToOffset TimeSpan.Zero

printfn $"{localTime} exactly equals {otherTime}: {localTime.EqualsExact otherTime}\n"

// Convert other time to UTC
let universalTime = localTime.ToUniversalTime()
printfn $"Universal time: {universalTime}"
printfn $"{otherTime} = {universalTime}: {universalTime.Equals otherTime}"

Hinweise

Diese Methode gibt ein DateTimeOffset Objekt zurück, dessen Offset Eigenschaft auf Null festgelegt ist.

Sowohl der Wert des aktuellen DateTimeOffset Objekts als auch der Wert des objekts, das DateTimeOffset vom Methodenaufruf zurückgegeben wird, stellen denselben Zeitpunkt dar. Wenn beide an die DateTimeOffset.Equals(DateTimeOffset, DateTimeOffset) Methode übergeben werden, wird die Methode zurückgegeben true.
