            StreamWriter objWriter = new StreamWriter("text.txt",true);
            string[] arrTest = new string[9];
            arrTest[0] = txtID.Text;
            arrTest[1] = txtName.Text;
            arrTest[2] = cmbGender.Text;
            arrTest[3] = txtAddress.Text;
            arrTest[4] = txtPhone.Text;
            arrTest[5] = txtPassport.Text;
            arrTest[6] = dateTPStartdate.Text;

            arrTest[8] = txtDescription.Text;
            //ind++;
            for (j = 0; j < 9; j++)
            {
                objWriter.WriteLine(arrTest[j]+" ");
            }
            objWriter.WriteLine();
            objWriter.Close();

从文件读取

Reading from a file

ListViewItem lis = new ListViewItem();

           FileInfo afile = new FileInfo("text.txt");
           if (afile.Exists)
           {
               StreamReader objReader = new StreamReader("text.txt", true);
               string textLine = "";
               do
               {
                   textLine = objReader.ReadLine();
                   lis.SubItems.Add(textLine);
               } while (objReader.Peek() != -1);

               listView1.Items.Add(lis);
               objReader.Close();
           }
           else {
               MessageBox.Show("There is no file");
           }

请帮帮我.

推荐答案

使用这种方法检查文件结尾.

Use this way to check end of file.

while ((textLine = objReader.ReadLine()) != null)
           {
                lis.SubItems.Add(textLine);
           }

您也可以尝试使用BinaryReader和BinaryWriter.对于结构化数据，它比StreamReader和StreamWriter更好.

Also you can try to use BinaryReader and BinaryWriter. It is better than StreamReader and StreamWriter for structural data.

如果对每个记录使用定界符，则将很容易读取记录.

请参阅 MSDN

Hi,

It will be easy to read record if you use delimiter for each record.

Please see MSDN
