# How to add/remove as needed?

• ### Question

• I was wondering if there is a better way to handle something like this?

```                    case 8:
polygon.Locations = new LocationCollection(){
new Location(double.Parse(warnPOLSplit[0]), double.Parse(warnPOLSplit[1])),
new Location(double.Parse(warnPOLSplit[2]), double.Parse(warnPOLSplit[3])),
new Location(double.Parse(warnPOLSplit[4]), double.Parse(warnPOLSplit[5])),
new Location(double.Parse(warnPOLSplit[6]), double.Parse(warnPOLSplit[7]))};
break;
case 10:
polygon.Locations = new LocationCollection(){
new Location(double.Parse(warnPOLSplit[0]), double.Parse(warnPOLSplit[1])),
new Location(double.Parse(warnPOLSplit[2]), double.Parse(warnPOLSplit[3])),
new Location(double.Parse(warnPOLSplit[4]), double.Parse(warnPOLSplit[5])),
new Location(double.Parse(warnPOLSplit[6]), double.Parse(warnPOLSplit[7])),
new Location(double.Parse(warnPOLSplit[8]), double.Parse(warnPOLSplit[9]))};
break;```
I have a variable set with the amount I need, but is it possible to make this without using a case statement? This number can get pretty high, and I feel like there should be a better way to handle this.

• Something like this?
```polygon.Locations = new LocationsCollection();
for(int i = 0; i < whatever / 2; i++) // 'whatever' is 8 or 10, etc.
{
int index = i * 2;
Location location = new Location(double.Parse(warnPOLSplit[index]), double.Parse(warnPOLSplit[index + 1]));
polygon.Locations.Add(location);
}```
