ConnectivityInterval.ConnectionDuration Property

public:
 property TimeSpan ConnectionDuration { TimeSpan get(); };

TimeSpan ConnectionDuration();

public System.TimeSpan ConnectionDuration { get; }

var timeSpan = connectivityInterval.connectionDuration;

Public ReadOnly Property ConnectionDuration As TimeSpan

Property Value

A Windows.Foundation.TimeSpan representing how long the interface remained connected during this interval. May be shorter than the actual live connection if the queried window started or ended mid-interval.

Examples

var profile = Windows.Networking.Connectivity.NetworkInformation.GetInternetConnectionProfile();
if (profile != null)
{
    var end = DateTime.UtcNow;
    var start = end - TimeSpan.FromHours(1);
    var states = new Windows.Networking.Connectivity.NetworkUsageStates();
    var intervals = await profile.GetConnectivityIntervalsAsync(start, end, states);

    double connectedSeconds = intervals.Sum(iv => iv.ConnectionDuration.TotalSeconds);
    double utilization = connectedSeconds / (end - start).TotalSeconds;
    // utilization now reflects fraction of the hour the interface was connected
}

Remarks

Notes

• Pair with ConnectivityInterval.StartTime to identify the full span.
• Does not imply any data transfer; combine with usage buckets from ConnectionProfile.GetNetworkUsageAsync for volume metrics.
• Can be truncated when your query window (start/end) slices through an active connection.
• Multiple intervals for a profile can have gaps (device sleep, transition, disconnect).
• Summing all ConnectionDuration values from a query window yields total connected time; divide by wall-clock span to compute utilization.
• For incremental processing, persist the end (StartTime + ConnectionDuration) of the last fully closed interval and resume from there to avoid recounting an interval still in progress.
