示例1: InitializeFixedStatementStringLocal

        private BoundStatement InitializeFixedStatementStringLocal(
            LocalSymbol localSymbol,
            BoundFixedLocalCollectionInitializer fixedInitializer,
            SyntheticBoundNodeFactory factory,
            out LocalSymbol stringTemp,
            out LocalSymbol localToClear)
        {
            TypeSymbol localType = localSymbol.Type;
            BoundExpression initializerExpr = VisitExpression(fixedInitializer.Expression);
            TypeSymbol initializerType = initializerExpr.Type;

            // intervening parens may have been skipped by the binder; find the declarator
            VariableDeclaratorSyntax declarator = fixedInitializer.Syntax.FirstAncestorOrSelf<VariableDeclaratorSyntax>();
            Debug.Assert(declarator != null);

            stringTemp = factory.SynthesizedLocal(initializerType, syntax: declarator, isPinned: true, kind: SynthesizedLocalKind.FixedString);

            // NOTE: we pin the string, not the pointer.
            Debug.Assert(stringTemp.IsPinned);
            Debug.Assert(!localSymbol.IsPinned);

            BoundStatement stringTempInit = factory.Assignment(factory.Local(stringTemp), initializerExpr);

            var convertedStringTemp = factory.Convert(
                localType,
                factory.Local(stringTemp),
                fixedInitializer.ElementPointerTypeConversion);

            BoundStatement localInit = AddLocalDeclarationSequencePointIfNecessary(declarator, localSymbol, 
                factory.Assignment(factory.Local(localSymbol), convertedStringTemp));

            BoundExpression notNullCheck = MakeNullCheck(factory.Syntax, factory.Local(stringTemp), BinaryOperatorKind.NotEqual);
            BoundExpression helperCall;

            MethodSymbol offsetMethod;
            if (TryGetWellKnownTypeMember(fixedInitializer.Syntax, WellKnownMember.System_Runtime_CompilerServices_RuntimeHelpers__get_OffsetToStringData, out offsetMethod))
            {
                helperCall = factory.Call(receiver: null, method: offsetMethod);
            }
            else
            {
                helperCall = new BoundBadExpression(fixedInitializer.Syntax, LookupResultKind.NotInvocable, ImmutableArray<Symbol>.Empty, ImmutableArray<BoundNode>.Empty, ErrorTypeSymbol.UnknownResultType);
            }

            BoundExpression addition = factory.Binary(BinaryOperatorKind.PointerAndIntAddition, localType, factory.Local(localSymbol), helperCall);
            BoundStatement conditionalAdd = factory.If(notNullCheck, factory.Assignment(factory.Local(localSymbol), addition));

            localToClear = stringTemp;
            return factory.Block(stringTempInit, localInit, conditionalAdd);
        }
