Currently when trying to do something in a method that takes an out parameter, I need to assign the value of the out parameter in the method body, e.g.
public static void TryDoSomething(int value, out bool itWorkerd)
{
itWorkerd = true;
if (someFavourableCondition)
{
// if I didn't assign itWorked variable before this point,
// I get an error: "Parameter itWorked must be assigned upon exit.
return;
}
// try to do thing
itWorkerd = // success of attempt to do thing
}
I'd like to be able to set a default value of the itWorked
parameter so I don't have to arbitrarily set the value in the body of the method.
public static void TryDoSomething(int value, out bool itWorkerd = true)
{
if (someFavourableCondition)
{
// itWorked was already assigned with a default value
// so no compile errors.
return;
}
// try to do thing
itWorkerd = // success of attempt to do thing
}
Why is it not possible to assign a default value for an out
parameter?
