12.3.3.1 General rules for statements

?v is not definitely assigned at the beginning of a function member body.

?v is definitely assigned at the beginning of any unreachable statement.

C# LANGUAGE SPECIFICATION

104

?The definite assignment state of v at the beginning of any other statement

is determined by checking

the definite assignment state of v on all control flow transfers that

target the beginning of that

statement. If (and only if) v is definitely assigned on all such control

flow transfers, then v is

definitely assigned at the beginning of the statement. The set of possible

control flow transfers is

determined in the same way as for checking statement reachability (?5.1).

?The definite assignment state of v at the end point of a block, checked,

unchecked, if, while,

do, for, foreach, lock, using, or switch statement is determined by

checking the definite

assignment state of v on all control flow transfers that target the end

point of that statement. If v is

definitely assigned on all such control flow transfers, then v is

definitely assigned at the end point of

the statement. Otherwise, v is not definitely assigned at the end point of

the statement. The set of

possible control flow transfers is determined in the same way as for

checking statement reachability
