Parameterless constructor in struct

public struct MyStruct
{
    public int id;
    static int count = 0;

    public MyStruct() //Not allowed?
    {
        id = count++;
    }
}

public struct MyStruct
{
    public int id;
    static int count = 0;

    public MyStruct() //Not allowed?
    {
        id = count++;
    }
}

Then public MyStruct[] myStruct = new MyStruct[100]; should call the MyStruct() constructor 100 times. How can I do this?

XY problem if I ever saw one, but you'd need count to be static for this to work and even so, I dont think that array construction would work the way you expect anyways

yeah I made a mistake but it won't let me edit the body of the post

why you abandoned your previous but almost similar post and make a new one, instead?

The title makes more sense in this one and is more explanatory

you need a factory the factory should have the count and assign the id if you're doing the same for all types, all the more reason for it to be implemented separately

Array elements are always created using the default value for the element’s type. Which does not involve the zero-param ctor.

Ah ok I see Thank you I will look into this

there is an Array.Initialize for this though
