How do I select every 6th element from a list (using Linq)
- by iDog
Hi, I've got a list of 'double' values. I need to select every 6th record. It's a list of coordinates, where I need to get the minimum and maximum value of every 6th value.
List of coordinates (sample): [2.1, 4.3, 1.0, 7.1, 10.6, 39.23, 0.5, ... ]
with hundrets of coordinates.
Result should look like: [x_min, y_min, z_min, x_max, y_max, z_max]
with exactly 6 coordinates.
Following code works, but it takes to long to iterate over all coordinates. I'd like to use Linq instead (maybe faster?)
for (int i = 0; i < 6; i++)
{
List<double> coordinateRange = new List<double>();
for (int j = i; j < allCoordinates.Count(); j = j + 6)
coordinateRange.Add(allCoordinates[j]);
if (i < 3) boundingBox.Add(coordinateRange.Min());
else boundingBox.Add(coordinateRange.Max());
}
Any suggestions?
Many thanks! Greets!
