Using the following struct def, how can I tell (using reflection) if "ba"
has the marshal attribute and get the "ByValArray" and maybe even the size?
In the bigger picture, given a struct (or a class), how to decide if
"sizeof(MyStruct)" would fail before calling sizeof and having to use
Marshal.sizeof? TIA
public struct MyStruct

Why do I get the following run time error:
Additional information: Type System.Object can not be marshaled as an
unmanaged structure; no meaningful size or offset can be computed.
When the following code is executed?
object test = new object();
int temp = Marshal.SizeOf(test);

I feel dumb to ask because I bet this is a simple question...
Looking at the code below, can someone please explain why I get two
different values in my Marshal.SizeOf calls (see the commented lines)?
TIA!

char a = 'p';
if (System.Runtime.InteropServices.Marshal.SizeOf(a) == 1)
dothis();
else
dothat();
SizeOf(a) is returned as 1. I thought chars were 16 bits in size. Why is it
returning 1 to me?
thanks

Hi.
Is is possible to mark a class-member-variable to avoid its marshaling?
class MyClass
{
int i_;
IntPtr point_;

I need to call into a C++ DLL from my C# code.
The function is expecting a void pointer to an unsigned short.
Which would be more correct?
UInt16 wRegData;
IntPtr p = Marshal.AllocHGlobal(Marshal.SizeOf(wRegData));
Marshal.StructureToPtr(wRegData, p, false);

Given this native struct:

I want to make managed equivalent, so I did this:

Hi All,
I am using System.Runtime.InteropServices; to marshal a structure using Marshal.structureToPtr().
But to get the size of structure when i get Marshal.sizeOf(), it gives me improper sizes.
Code:
public struct IDName
{
public ushort Id;

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
