C#：不确定参数个数传参 关键字 params

using Microsoft.VisualBasic;

using System.Diagnostics;
using System.Threading;
using System.Windows.Forms;

namespace WindowsFormsApp13 {
    public partial class Form1 : Form {
        

        public Form1() {
            InitializeComponent();
        }
        

        private void Form1_Load(object sender, EventArgs e) {

        }

        private void button1_Click(object sender, EventArgs e) {
            int[] a = { 0,1,2,3,4,5,6,7,8,9};
            //print(a); 可以用下面的方式进行不确定参数个数传参，如果不用关键字 params，则只能传如一个数组
            print(0,1,2,3,4,5,6,7,8,9,1,11,13,13,14,15);
        }

        public void print(params int[] a) {
            Debug.WriteLine(String.Join(",",a));
        }

    }
}
