Definition

Namespace:

Windows.ApplicationModel.Appointments

Gets or sets a time span that represents the time duration of the appointment. Duration is of type TimeSpan and must be non-negative.

public:
 property TimeSpan Duration { TimeSpan get(); void set(TimeSpan value); };

TimeSpan Duration();

void Duration(TimeSpan value);

public System.TimeSpan Duration { get; set; }

var timeSpan = appointment.duration;
appointment.duration = timeSpan;

Remarks

This property uses a time span value, which is represented differently depending on which language you are programming with.

• In JavaScript, set the Duration value with a Number that represents the time interval. Each unit for a TimeSpan value represents 1 millisecond. For example, this code sets a Duration value to 60 minutes (one hour). ```javascript appointment.duration = (60 * 60 * 1000); // 1 hour in 1-millisecond units

+ In Visual C++ component extensions (C++/CX), use a <xref href="Windows.Foundation.TimeSpan?text=TimeSpan" /> structure value with a **Duration** value. In Visual C++ component extensions (C++/CX), each unit for a **Duration** value represents 100 nanoseconds.
+ In C# or Microsoft Visual Basic, you use a [System.TimeSpan](/dotnet/api/system.timespan?view=dotnet-uwp-10.0&preserve-view=true) value. You can use utility API of [System.TimeSpan](/dotnet/api/system.timespan?view=dotnet-uwp-10.0&preserve-view=true) such as [FromSeconds](/dotnet/api/system.timespan.fromseconds?view=dotnet-uwp-10.0&preserve-view=true) to generate a [System.TimeSpan](/dotnet/api/system.timespan?view=dotnet-uwp-10.0&preserve-view=true) and set the value.




> [!NOTE]
> In JavaScript, <xref href="Windows.Foundation.TimeSpan?text=TimeSpan" /> is accessed as a value, not as an object. For example, use `var a = 10000`, not `var a = { duration: 10000 }`. Also, in JavaScript, <xref href="Windows.Foundation.TimeSpan?text=TimeSpan" /> is treated as the number of millisecond intervals, not the number of 100-nanosecond intervals so you can lose precision when you port <xref href="Windows.Foundation.TimeSpan?text=TimeSpan" /> values between languages.
