// Now, explicitly state what the parameter type.

List evenNumbers = list.FindAll((int i) => (i % 2) == 0);

As you have seen, if a lambda expression has a single, implicitly typed parameter, the parenthe-

ses may be omitted from the parameter list. If you wish to be consistent regarding your use of

lambda parameters, you are free to 

always wrap the parameter list within parentheses, leaving us

with this expression:

C H A P T E R   1 1

D E L E G AT E S, E V E N T S, A N D   L A M B D A S

List evenNumbers = list.FindAll((i) => (i % 2) == 0);

Finally, notice that currently our expression has not been wrapped in parentheses (we have of

course wrapped the modulo statement to ensure it is executed first before the test for equality).

Lambda expressions do allow for the statement to be wrapped as follows:
