The best way to implement a structure like a Union

[=?Utf-8?B?RWl0YW4=?=]

Hello,

I would like to have a structure similar to C++ Union. What would be the
best way to do it in C#?

Thanks

I have some recollection that the FieldOffsetAttribute class can be used
for this purpose, by specifying the same offset for multiple field
within the struct.

I might be misremembering, but just in case I'm not, you might want to
look here:

For example:
C++:
union Foo
{
int i;
bool b;
};
C#:
using System.Runtime.InteropServices;
//C++ TO C# CONVERTER TODO TASK: Unions are not supported in C#, but the
following union can be simulated with the StructLayout and FieldOffset
attributes.
//ORIGINAL LINE: union Foo
[StructLayout(LayoutKind.Explicit)]
public struct Foo
{
[FieldOffset(0)]
public int i;
[FieldOffset(0)]
public bool b;
}
