如何将此Python算法转换为C#

# Python算法示例
def fibonacci(n):
    if n <= 0:
        return []
    elif n == 1:
        return [0]
    elif n == 2:
        return [0, 1]
    else:
        fib = [0, 1]
        for i in range(2, n):
            fib.append(fib[i-1] + fib[i-2])
        return fib

# 将Python算法转换为C#的代码
public static List<int> Fibonacci(int n)
{
    if (n <= 0)
    {
        return new List<int>();
    }
    else if (n == 1)
    {
        return new List<int> { 0 };
    }
    else if (n == 2)
    {
        return new List<int> { 0, 1 };
    }
    else
    {
        List<int> fib = new List<int> { 0, 1 };
        for (int i = 2; i < n; i++)
        {
            fib.Add(fib[i - 1] + fib[i - 2]);
        }
        return fib;
    }
}
