示例1: ComputeSequentialFieldLayout

        private static ComputedInstanceFieldLayout ComputeSequentialFieldLayout(MetadataType type, int numInstanceFields)
        {
            var offsets = new FieldAndOffset[numInstanceFields];

            // For types inheriting from another type, field offsets continue on from where they left off
            int cumulativeInstanceFieldPos = ComputeBytesUsedInParentType(type);

            int largestAlignmentRequirement = 1;
            int fieldOrdinal = 0;
            int packingSize = ComputePackingSize(type);

            foreach (var field in type.GetFields())
            {
                if (field.IsStatic)
                    continue;

                var fieldSizeAndAlignment = ComputeFieldSizeAndAlignment(field.FieldType, packingSize);

                if (fieldSizeAndAlignment.Alignment > largestAlignmentRequirement)
                    largestAlignmentRequirement = fieldSizeAndAlignment.Alignment;

                cumulativeInstanceFieldPos = AlignmentHelper.AlignUp(cumulativeInstanceFieldPos, fieldSizeAndAlignment.Alignment);
                offsets[fieldOrdinal] = new FieldAndOffset(field, cumulativeInstanceFieldPos);
                cumulativeInstanceFieldPos = checked(cumulativeInstanceFieldPos + fieldSizeAndAlignment.Size);

                fieldOrdinal++;
            }

            if (type.IsValueType)
            {
                var layoutMetadata = type.GetClassLayout();
                cumulativeInstanceFieldPos = Math.Max(cumulativeInstanceFieldPos, layoutMetadata.Size);
            }

            SizeAndAlignment instanceByteSizeAndAlignment;
            var instanceSizeAndAlignment = ComputeInstanceSize(type, cumulativeInstanceFieldPos, largestAlignmentRequirement, out instanceByteSizeAndAlignment);

            ComputedInstanceFieldLayout computedLayout = new ComputedInstanceFieldLayout();
            computedLayout.FieldAlignment = instanceSizeAndAlignment.Alignment;
            computedLayout.FieldSize = instanceSizeAndAlignment.Size;
            computedLayout.ByteCountUnaligned = instanceByteSizeAndAlignment.Size;
            computedLayout.ByteCountAlignment = instanceByteSizeAndAlignment.Alignment;
            computedLayout.Offsets = offsets;

            return computedLayout;
        }
