c# Windows Form遇到问题

schnappie 2010-07-26 10:57:53

各位前辈，我想编写如图这个程序

目的是寻找一个txt文档，读取里面的x,y,z值，然后在form2里画出关于z的图。现在我能写的是可以读取x,y,z. RichtextBox上也能显示出txt文档里的内容。但是把x,y,z的值调到Form2里运用，我不会。请那位好心的大大写下详细的代码，谢谢
我写的代码如下

Form1.cs



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.IO;

using System.Collections;





namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        

        {

            InitializeComponent();

        }



        private void path_Click(object sender, EventArgs e)

        {

            

            

            OpenFileDialog openFileDialog1 = new OpenFileDialog();



            openFileDialog1.InitialDirectory = "c:\\";

            openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";



            openFileDialog1.FilterIndex = 2;

            openFileDialog1.RestoreDirectory = true;



            if (openFileDialog1.ShowDialog() == DialogResult.OK)

            {

                textBox1.Text = openFileDialog1.FileName;

                    

            }



        }



  

        

        

        

        private void Cancel_Click(object sender, EventArgs e)

        {

            textBox1.Text = "";

            richTextBox1.Text = "";



        }



        private void OK_Click(object sender, EventArgs e)

        {

            if (textBox1.Text == "")//&& int.Parse(textBox1.Text) != 0)

            {

                //this.timer1.Interval = int.Parse(this.textBox1.Text);

                richTextBox1.Text = "";

                MessageBox.Show("Please choose a File！");

                //this.richTextBox1.Text = "";



            }





            else

          

            {

                FileStream fs = new FileStream(textBox1.Text, FileMode.Open, FileAccess.Read);

                StreamReader m_streamReader = new StreamReader(fs);



                

                m_streamReader.BaseStream.Seek(0, SeekOrigin.Begin);

                

                this.richTextBox1.Text = "";

                string strLine = m_streamReader.ReadLine();

                

                

                while (strLine != null)

                {

                    this.richTextBox1.Text += strLine + "\n";

                    strLine = m_streamReader.ReadLine();

                

                }



                

                m_streamReader.Close();

                string textline;

                

                ArrayList text = new ArrayList();

                StreamReader freader = File.OpenText(textBox1.Text);

                while ((textline = freader.ReadLine()) != null)

                {

                    if (textline.Length == 0)

                        continue;

                    text.Add(textline);

                 }



                

            }



            Form2 frm = new Form2();

            frm.Show();



        }





        

    }

}

Form2





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.IO;

using System.Collections;



namespace WindowsFormsApplication1

{

    public partial class Form2 : Form

    

    {

        public Form2() 



        {

            InitializeComponent();

        }



        private void richTextBox1_TextChanged(object sender, EventArgs e)

        {

           

        }



      

    }

}

你希望Error1.txt文件中的这些数据在Form2上的图表中显示成什么样子？

  定义一个结构体

  Struct XYZvalue

  { 

    int x;

    int y;

    int z;

  }

  Form2中定义这样一个变量

  public List<XYZvalue> list=null;

  然后

  将Form1中X,y,z点对象传过不来

  Form2 frm=Form2();

  frm.list=//form1中xyz点的集合

  frm.Show();
