    public Range GetCurrentRangeAtTime( 
       TimeSpan time
    )
    Public Function GetCurrentRangeAtTime( _
       ByVal time As TimeSpan _
    ) As Range

    Parameters

    time
    The time at which to return the map range.
    Exceptions
    ExceptionDescription
    This method or property must be called within the lambda passed to QueuedTask.Run.
    Example
    Interpolate Range
    public Task<List<ArcGIS.Desktop.Mapping.Range>> GetInterpolatedMapRanges()
    {
      //Return the collection representing the map time for each frame in animation.
      return QueuedTask.Run(() =>
      {
        var mapView = MapView.Active;
        if (mapView != null || mapView.Animation == null)
          return null;
    
        var animation = mapView.Map.Animation;
    
        var ranges = new List<ArcGIS.Desktop.Mapping.Range>();
        //We will use ticks here rather than milliseconds to get the highest precision possible.
        var ticksPerFrame = Convert.ToInt64(animation.Duration.Ticks / (animation.NumberOfFrames - 1));
        for (int i = 0; i < animation.NumberOfFrames; i++)
        {
          var time = TimeSpan.FromTicks(i * ticksPerFrame);
          //Because of rounding for ticks the last calculated time may be greeting than the duration.
          if (time > animation.Duration)
            time = animation.Duration;
          ranges.Add(mapView.Animation.GetCurrentRangeAtTime(time));
        }
        return ranges;
      });
    }
