小编Mat*_*att的帖子

我在C#中遇到问题,输出状态:

Error   1   Static class 'WindowsFormsApplication1.Hello2' 
cannot derive from type 'System.Windows.Forms.Form'. Static classes 
must derive from object.

我怎么能纠正这个？

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

        }

        private void button1_Click(object sender, EventArgs e)
        {
             Hello2.calculate();
        }
    }



    public class Hello : Form
    {
        public string test { get; set; }

    }


    public static class Hello2 : Form
    {
        public static void calculate()
        {
            Process.Start("test.exe");

        }
    }
