Do lambdas paste?

Question

make simple lambda expressions inline?

I have a tendency (thanks to f # and other functional incursions) to encapsulate repeating code present in one function in lambda and call it instead. I am curious if as a result there will be overhead at runtime:

var foo = a + b;
var bar = a + b;

v

Func<T1, T2> op = () => a + b;
var foo = op();
var bar = op();

which one is worth more?

Answer 1

No. Lambda functions are not built-in, but instead are stored as delegates under the hood and carry the same execution cost as other delegates.
