C#

The following definite assignment rules apply to output parameters. Note the different
rules for reference parameters described in §5.1.5.
• A variable need not be definitely assigned before it can be passed as an output parameter
in a function member or delegate invocation.
• Following the normal completion of a function member or delegate invocation,
each variable that was passed as an output parameter is considered assigned in that execution path.
• Within a function member or anonymous function, an output parameter is considered
initially unassigned.
• Every output parameter of a function member or anonymous function must be definitely
assigned (§5.3) before the function member or anonymous function returns normally.
