Yes you can have a list in struct but you cannot initialise it with a field initialiser and instead you must use the constructor.

struct MyStruct
{
    public List<string> MyList;
    public int MyInt;

    public MyStruct(int myInt)
    {
        MyInt = myInt;
        MyList = new List<string>();
    }
}

You can do that - declare a constructor for the struct and create a list instance in the struct constructor. You can't use an initializer as you proposed in your code snippet.

I am not an expert in C# but a structure is just a prototype of how your memory would look. You will have to declare a structure variable to be able to do "new list()" and assign it to a list variable.

something like struct test a; a.y = new list();

I have never programmed in C# so please convert my C syntax to C#.

struct can have a constructor and you can instantiate the list in the constructor.
