    Can only use array initializer expressions to assign to array types. Try using a new expression instead

using System;

struct sample
{
    public int a=10;
    public int b=20;
}

class Employee
{
    static void Main(string[] args)
    {
        sample S;

        Console.WriteLine(S.a + " " + S.b);
    }
}
