Why does struct alignment depend on whether a field type is …

WebFor primitive types, the alignment is usually the same as the size of the type. For example, an int is 4 bytes in size and is typically aligned on a 4-byte boundary. A double is 8 bytes in size and is typically aligned on an 8-byte boundary. These alignments are fixed and do not depend on the context of the field within a struct. WebJun 2, 2024 · Struct In C#.
