    Range Class
    In This Topic
    Represents a range of values defined by a min and a max.
    Syntax
    public class Range 
    Public Class Range 
    Remarks
    Range contains two properties Min and Max which defines the range of values. Either property can be set to null. When Min is null it means the range has no lower bound or the range is less than or equal to the Max. When Max is null it means the range has no upper bound or the range is greater than or equal to the Min.
    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;
      });
    }
