Here is my code in Form.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;

namespace Practice_3
{
public partial class Form1 : Form
{
private frmGlass _frmGlass;
private frShow _frmshow;
private Turism[] indexclass = new Turism[100];
int idex = 0;
public Form1()
{
InitializeComponent();
}

Turism add = new Turism();

private void btnAdd_Click(object sender, EventArgs e)
{
if (txtid.Text == "" || txtname.Text == "" || txtgender.Text == "" || txtaddress.Text == "" || txtpassport.Text == "" || datestart.Text == "" || enddate.Text == "")
{
MessageBox.Show("Sorry!Don't have value for insert ."+"\n"+"Please insert value");
}
else
{
indexclass[idex] = new Turism();
indexclass[idex].ID = txtid.Text;
indexclass[idex].Name = txtname.Text;
indexclass[idex].Gender = txtgender.Text;
indexclass[idex].Address = txtaddress.Text;
indexclass[idex].Phone = txtphone.Text;
indexclass[idex].Passport = txtpassport.Text;
indexclass[idex].Stardate = datestart.Text;
indexclass[idex].Enddate = enddate.Text;
indexclass[idex].Discrpition = txtDetail.Text;
++idex;

clear();
btnShow.Enabled = true;
}

}

private void btnShow_Click(object sender, EventArgs e)
{

_frmGlass = new frmGlass();
_frmshow = new frShow(_frmGlass, indexclass, idex);
_frmGlass.Show();
_frmshow.Show(_frmGlass);

}
internal void clear()
{
txtid.Text = "";
txtaddress.Text = "";
txtgender.Text = "";
txtname.Text = "";
txtpassport.Text = "";
txtphone.Text = "";
txtDetail.Text = "";
}

private void btnClears_Click(object sender, EventArgs e)
{
clear();
}

private void button1_Click(object sender, EventArgs e)
{
Close();

}

private void Form1_Load(object sender, EventArgs e)
{
txtgender.Text = "Male";
btnShow.Enabled = false;
}

}
}

It sounds like you will want to store your results in a List<t> as well as your ListView and then write the contents of the list out to a file. i.e.

C#

List<string> resultData = new List<string>();
resultData.Add("Some result data");

etc...

C#

using (StreamWriter writer = new StreamWriter("pathOfFileToSaveDataTo"))
{
    for (int i = 0; i < resultData.Count; i++)
    {
        writer.WriteLine(resultData[i]);
    }

    writer.Close();
}

hope this helps.

EDIT:
You could also just write the contents of the ListView out to the file without storing the results in a List<T> if you wanted to.
