关于用方法绘制控件的问题

Question

我要在WinForm程序中调用一个方法中声明的一些控件
但是总是提示【未将对象引用设置到对象的实例。】
是不是我的思路有问题啊，请高手指点！winform代码：
private void Form1_Load(object sender, EventArgs e)
{
    Class1 c1 = new Class1();
    c1.Component();
    this.Controls.Add(c1.textBox2);
}
被调用绘制控件代码:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;namespace WindowsApplication1
{
    class Class1
    {
        private System.Windows.Forms.TextBox textBox1;
        public System.Windows.Forms.TextBox textBox2;
        public System.Windows.Forms.Panel panel1;        public void Component()
        {
            // 
            // panel1
            // 
            //【未将对象引用设置到对象的实例。】            this.panel1.Location = new System.Drawing.Point(13, 85);
            this.panel1.Name = "panel1";
            this.panel1.Size = new System.Drawing.Size(200, 100);
            this.panel1.TabIndex = 0;
            // 
            // textBox1
            // 
            this.textBox1 = new System.Windows.Forms.TextBox();
            //this.textBox1.Location = new System.Drawing.Point(40, 40);
            //this.button1.Margin = new System.Windows.Forms.Padding(100);
            this.textBox1.Name = "textBox2";
            this.textBox1.Size = new System.Drawing.Size(100, 21);
            //this.Controls.Add(textBox1);
            // 
            // textBox2
            // 
            this.textBox2 = new System.Windows.Forms.TextBox();
            //this.textBox2.Location = new System.Drawing.Point(40, 40);
            //this.button1.Margin = new System.Windows.Forms.Padding(100);
            this.textBox2.Name = "textBox2";
            this.textBox2.Size = new System.Drawing.Size(100, 21);
            //this.Controls.Add(textBox2);            panel1.Controls.Add(textBox1);
            panel1.Controls.Add(textBox2);
        }
    }
}
