[C#] Comunicazione tra classi e form

[22kakà]

Scusami non ci avevo pensato ....

Form1:

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

namespace Client
{
    public partial class Form1 : Form
    {
        public static Class1 Classe;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Classe = new Class1();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Class1.aaz();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            Class1.bbbx();
        }
    }
}

Class1:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Client
{
    public class Class1
    {
        public static Form1 Form = new Form1();

        public static void aaz()
        {
            Form.textBox1.Text = "Prova Testo";
            Form.Show();
        }
        public static void bbbx()
        {
            Form.textBox1.Text += "Prova Testo Accodato";
            Form.Show();
        }
    }
}

Questo progetto mi serve solo come test per poi includerlo in un altro ...
