现在给大家介绍一种最简单的跨窗体操作

WinForm的窗体是一个类，C#的类是引用类型，那么我们应该可以将WinForm窗体类进行传递，那不就可以进行操作了么？

From1

using System;
using System.Windows.Forms;

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

        private void 打开form2隐藏form1_Click(object sender, EventArgs e)
        {
            Form2 f = new Form2();
            f.fatherForm = this;
            f.Show();
            this.Hide();
        }
    }
}

Form2

using System;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        public Form1 fatherForm;

        private void 打开from3_Click(object sender, EventArgs e)
        {
            Form3 f = new Form3();
            f.fatherForm = this;
            f.Show();
        }
    }
}

Form3

using System;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form3 : Form
    {
        public Form3()
        {
            InitializeComponent();
        }

        public Form2 fatherForm;

        private void 关闭form3from2显示from1_Click(object sender, EventArgs e)
        {
            fatherForm.fatherForm.Show();
            fatherForm.Close();
            this.Close();
        }

    }
}
