您需要获取表单的实例。请参阅表格1下面的两个表格项目

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 WindowsFormsApplication1{    public partial class Form1 : Form    {        Form2 form2;        public Form1()        { InitializeComponent(); form2 = new Form2(this);        }        private void button1_Click(object sender, EventArgs e)        { form2.Show(); string  results = form2.GetData();        }    }}

表格2

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 WindowsFormsApplication1{    public partial class Form2 : Form    {        Form1 form1;        public Form2(Form1 nform1)        { InitializeComponent(); this.FormClosing +=  new FormClosingEventHandler(Form2_FormClosing); form1 = nform1; form1.Hide();        }        private void Form2_FormClosing(object sender, FormClosingEventArgs e)        { //stops form from closing e.Cancel = true; this.Hide();        }        public string GetData()        { return "The quick brown fox jumped over the lazy dog.";        }    }}
