Question

I need to split an input value high/low that might come in three different forms: 120/50, 120/, /50, 120.

I would like to split this into two different variables and check the values I got.

var high = input.Split('/').First();
var low = input.Split('/').Last();

if (high.Length > 0) //Do this
if (low.Length > 0) //Do that  

The problem is that with the two last inputs I get the same value in both high and low. Which means I can’t tell if I got a high value or a low.

I’m starting to suspect I can’t use split here?

EDIT
It seems as if there are values with no / at all. Those values should be interpreted as high values.

You could use Nullables and TryParse which is safer:

string[] parts = input.Split('/');
int? high = null;
int? low = null;
int hightest, lowtest;
if(int.TryParse(parts[0], out hightest))
    high = hightest;
if(int.TryParse(parts[1], out lowtest))
    low = lowtest;

Now you can check if they are set with the HasValue property, for example:

if(high.HasValue)
{
    int val = high.Value;
    // do something with it
}
