what x , y stands for?

  • x single result, of type of elements in results sequence.
  • y single member, of type of elements in x.members sequence.

these lambda expressions (x => x.whatever) introduced language c# 3, x input, , right side (x.whatever) output (in particular usage scenario).

an easier example

var list = new list<int> { 1, 2, 3 }; var oddnumbers = list.where(i => % 2 != 0);

here, i single int item input expression. i % 2 != 0 boolean expression evaluating whether input or odd. entire expression (i => % 2 != 0) predicate, func<int, bool>, input integer , output boolean. follow? iterate on query oddnumbers, each element in list sequence evaluated against predicate. pass become part of output. 

foreach (var item in oddnumbers)     console.writeline(item);  // writes 1, 3
