(int, double) t = (1, 0.5);
(int i, double d) = t;
d

(int, double) t = (1, 0.5);
(int i, double d) = t;
d

wdym like pass a tuple to a method that expects seperate args? no i dont think thats possible

Down•2y ago

public void Method1(double arg1, double arg2) ...

Method1(tuple[0], tuple[1])
Method1(...) unpack tuple there

public void Method1(double arg1, double arg2) ...

Method1(tuple[0], tuple[1])
Method1(...) unpack tuple there

okay

sibber•2y ago

also you cant index tuples

Down•2y ago

o so how do i access values

sibber•2y ago

either name the values, or .Item1, .Item2 etc

You can make your own

public readonly record struct Point(double X, double Y);

public readonly record struct Point(double X, double Y);
