operator overld. struct vs. class

[Jesper]

Hi,

Are there any serious drawbacks using a class instead of
struct to implementing your own type.

I a textbook of mine on C# the author recommend operator
overloading on value types only. Apparantly based on some
argument that e.g. the ++ operator is more complex to
implement. Can this really be his only reason for this
argument?

Moreover, in a struct, the same aurthor defines the
following

struct Hour
{
.....
.....
private int value;
}

Does he obtain something special using the value keyword
as a field of the struct?

Best regards Jesper

Overloading operators may be a bit more detailed with reference types
but I wouldn't say it's more complex. You just have to make sure your
overload has the type of semantics you'd expect from it.

Nope. C# will let you use this keyword as just another variable name.
