c# - Func and lambda question -
i have declaration of
void test (func<bool> f) i have method bool getitem(string id)
i can call test ( ()=>getitem("123")), why?
i suppose can check need 1 string parameter.
func<bool> expects function returns bool. func<t1> has 1 output argument, func<t1, t2> takes function input t1 , output t2. each successive version allows additional input argument, final generic type being type of output argument.
ex.: func<string, string, bool> able invoke bool dostuff(string s1, string s2)
quick edit clarify: test( () => getitem("123")) works because start of lambda declaration exposes no input arguments, , getitem returns boolean.
