Having never ‘learned’ c#, the LINQ syntax sometimes escapes me, and it takes a bit of getting used to, but honestly, it’s worth the price of admission! I recently needed to find the first object in a list whose Y value was greater than another Y value (basically making sure it was on screen).
My first thought was to use a foreach loop, with a break and a bool flag along with a var to store the index like so:
bool found = false;
int rowIndex = 0;
foreach (float y in rowYPos)
found = true;
This code works, and will return the index of the first entry that exceeds scrollOffset;
However, with LINQ all that becomes:
int firstRowIndex = rowYPos.FindIndex(x=>x>scrollOffset);
Much shorter, less local vars and pretty self-explanatory. I didn’t benchmark it to see which was faster, though my hope is that the LinQ method would be, It’s not something that happens often enough to make it a worry.
Handy tip: You’ll need to add a using System.Linq; to the start of the file…
