List of references to strcutures

Pavel

Hello,

I believed that structure is a reference type.

Then I assign arrA_1[0]. struct_member2:

and check lst_A[0]. struct_member2:

The check_value should be 10, but it isn't. Why ?

Thanks in advance.

.... but why you expect 10.its working fine according struct rule.
I've been mistaken with assignment. Indeed, with this
arrA_1[2].struct_member2=10;
one can't expect 10 for check_value
intcheck_value=lst_A[0].struct_member2
but with
arrA_1[0].struct_member2=10;
check_value is expected to be 10 (of cause if one assumes erroneously that struct is reference type). But, ok, ... ifstruct is replaced by class, this example works perfectly.

yes you are doing good,and struct is value type not reference type.
but why you expect 10.its working fine according struct rule.

Please check MSDN pages for struct and you will find that it is value type .

You belief is absolutely wrong, struct is value type, if you open the implementation of struct, you will see it inherits System.ValueType, so that being said then you should get that why you see value 10for one and not the other. If you need reference type then use class instead of struct as @Pavel mentioned.

Resolved.
The structure struct_A must be changed to class class_A and it's Ok.
