实现

窗体的显示

如果要在一个窗体中通过按钮打开另一个窗体，就必须调用Show方法来显示窗体。

Form2 form2 = new Form2();
form2.Show();

窗体的隐藏

通过调用Hide方法可以隐藏窗体

Form2 form2 = new Form2();
form2.Hide();

举例

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace EMS
{
    public partial class Form1 : Form
        
    {
        Form2 form2 = new Form2();
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
         
            form2.Show();
        }

        private void button2_Click(object sender, EventArgs e)
        {
        
            form2.Hide();
        }
    }
}

效果
