c#如何跨窗体调用非静态函数，获取另外窗体的textbox值？

Question

form1代码

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;
using System.Data.OleDb;
using WeifenLuo.WinFormsUI.Docking;

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

    private void button1_Click(object sender, EventArgs e)
    {
        Form2.GetModel();
        textBox1.Text = Form2.str;
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        Form2 f2 = new Form2();
        f2.Show(dockPanel1);
        f2.DockTo(dockPanel1, DockStyle.Fill);
    }







}

}
#form2代码
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;
using WeifenLuo.WinFormsUI.Docking;

namespace KCTan
{

public partial class Form2 : DockContent
{
    public Form2()
    {
            InitializeComponent();         
    }

    public static String str = "";  //在窗体类里定义静态变量

    public void GetValue()
    {
        str = textBox1.Text;
    }
    public static void GetModel()
    {
        Form2 GM = new Form2();
        GM.GetValue();
    }

}

}

窗体二里面定义一个Action， public Action callBack;窗体一调用窗体二的时候使用此回调函数并且返回string值。
