在类中方法遇到了表达式项'['的问题

internal class Ellipse
{
    int[] point1 = new int[2];
    int[] point2 = new int[2];
    public void Getpoint1()
    {
        Console.WriteLine(point1);
    }
    public void Setpoint1()
    {
        int m = Convert.ToInt32(Console.ReadLine());
        int n = Convert.ToInt32(Console.ReadLine());
        point1 =[ m, n];
    }
}

}

这是c#，不是python。
point1[0] = m;
point1[1] = n;
