namespace app

			this.button1.Name = "button1";
			this.button1.TabIndex = 0;
			this.button1.Text = "enc";
			this.button1.Click += new System.EventHandler(this.button1_Click);

			this.button2.Location = new System.Drawing.Point(300, 270);
			this.button2.Name = "button1";
			this.button2.TabIndex = 0;
			this.button2.Text = "dec";
			this.button2.Click += new System.EventHandler(this.button2_Click);

			this.textBox1.Location = new System.Drawing.Point(30, 20);
			this.textBox1.Multiline = true;
			this.textBox1.Name = "textBox1";
			this.textBox1.Size = new System.Drawing.Size(300, 100);
			this.textBox1.TabIndex = 2;
			this.textBox1.Text = "base64 テストコード";

			this.textBox2.Location = new System.Drawing.Point(30, 160);
			this.textBox2.Multiline = true;
			this.textBox2.Name = "textBox2";
			this.textBox2.Size = new System.Drawing.Size(300, 100);
			this.textBox2.TabIndex = 2;
			this.textBox2.Text = "";

			this.textBox3.Location = new System.Drawing.Point(30, 300);
			this.textBox3.Multiline = true;
			this.textBox3.Name = "textBox3";
			this.textBox3.Size = new System.Drawing.Size(300, 100);
			this.textBox3.TabIndex = 2;
			this.textBox3.Text = "";

			this.ClientSize = new System.Drawing.Size(400, 500);
			this.Controls.AddRange(new Control[] {
				this.button1,
				this.button2,
				this.textBox1,
				this.textBox2,
				this.textBox3
			});
			this.Name = "Form1";
			this.Text = "base64";
		}
		private void button1_Click(object sender, System.EventArgs e) {
			this.textBox2.Text = Convert.ToBase64String(Encoding.UTF8.GetBytes(this.textBox1.Text));
		}
		private void button2_Click(object sender, System.EventArgs e) {
			this.textBox3.Text = Encoding.UTF8.GetString(Convert.FromBase64String(this.textBox2.Text));
		}
		[STAThread]
		static void Main() {
			Application.Run(new Form1());
		}
	}
}

以上。
