示例1: RewriteIntPtrConversion

        private BoundExpression RewriteIntPtrConversion(
            BoundConversion oldNode,
            SyntaxNode syntax,
            BoundExpression rewrittenOperand,
            Conversion conversion,
            bool @checked,
            bool explicitCastInCode,
            ConstantValue constantValueOpt,
            TypeSymbol rewrittenType)
        {
            Debug.Assert(rewrittenOperand != null);
            Debug.Assert((object)rewrittenType != null);

            TypeSymbol source = rewrittenOperand.Type;
            TypeSymbol target = rewrittenType;

            SpecialMember member = GetIntPtrConversionMethod(source: rewrittenOperand.Type, target: rewrittenType);
            MethodSymbol method = GetSpecialTypeMethod(syntax, member);
            Debug.Assert(!method.ReturnsVoid);
            Debug.Assert(method.ParameterCount == 1);

            conversion = conversion.SetConversionMethod(method);

            if (source.IsNullableType() && target.IsNullableType())
            {
                Debug.Assert(target.IsNullableType());
                return RewriteLiftedUserDefinedConversion(syntax, rewrittenOperand, conversion, rewrittenType);
            }
            else if (source.IsNullableType())
            {
                rewrittenOperand = MakeConversionNode(rewrittenOperand, source.StrippedType(), @checked);
            }

            rewrittenOperand = MakeConversionNode(rewrittenOperand, method.ParameterTypes[0], @checked);

            var returnType = method.ReturnType;
            Debug.Assert((object)returnType != null);

            if (_inExpressionLambda)
            {
                return BoundConversion.Synthesized(syntax, rewrittenOperand, conversion, @checked, explicitCastInCode, constantValueOpt, rewrittenType);
            }

            var rewrittenCall = MakeCall(
                    syntax: syntax,
                    rewrittenReceiver: null,
                    method: method,
                    rewrittenArguments: ImmutableArray.Create(rewrittenOperand),
                    type: returnType);

            return MakeConversionNode(rewrittenCall, rewrittenType, @checked);
        }
