WebWell, 16 bytes is 16 bytes. It will depend upon the variable types used in the struct, and how many bytes each variable uses up. But a string could more or less than 16. However, the size of the struct doesn't necessarily equal the sum of all individual field sizes due to padding/alignment. Web2 days ago · 1. Remove the Pack = 8 and the [MarshalAs (UnmanagedType.U8)], and replace the long with int. Also verify that your _API expands to something like __stdcall, otherwise fix the calling convention in the DllImport too. – GSerg. yesterday. FYI, _API would be reserved for compiler use in C++. – ChrisMM.

WebApr 29, 2024 · is reference type so struct contains only "pointer" so size is 8. and you could check it with Unsafe.SizeOf - struct B, struct C: Marshall.SizeOf shows 8 as it just references and both string and array will be marshalled as pointers so the size is 8. same will be in managed memory and Unsafe.SizeOf will show 8 to; 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. iphone 6s logic board tester

WebAug 21, 2024 · Size of struct: 24 The red portion represents the padding added for data alignment and the green portion represents the struct members. In this case, x (int) is followed by z (double), which is larger in size as compared to x. Hence padding is added after x. Also, padding is needed at the end for data alignment.
