嗨，当涉及到 c# 时，我是一个相当新手，我一直在尝试读出一个文本文件，然后将其拆分为带有类的部分，但是在声明它们的位置以及如何循环浏览记录方面遇到了麻烦。这是我的代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.IO;
using System.Collections;
using System.Windows.Forms;
namespace Assignment_3
{
public partial class Form1 : Form
{
string s;
string ss;
int i = 1;
string infilename;
int num;
SortedList sList = new SortedList();
int x = 0;
public Form1()
{
InitializeComponent();
student myself = new student();
infilename = "text.txt";
StreamReader sr1 = new StreamReader(infilename);
sList.Clear();
while ((s = sr1.ReadLine()) != null)
{
string[] strs = s.Split(',');
myself.firstname = strs[0];
myself.middlename = strs[1];
myself.surname = strs[2];
myself.dob = DateTime.Parse(strs[3]);
myself.dob.ToString(strs[3]);
myself.sex = strs[4];
ss = myself.dob.ToString("u");
sList.Add(myself.firstname, myself);
}
sr1.Close();
num = sList.Count;
student[] pArray = new student[num];
string[] keys = new string[num];
foreach (DictionaryEntry d in sList)
{
keys[x] = (string)d.Key;
pArray[x] = (student)d.Value;
x++;
}
if (i == 0)
{lblmessage.Text = "Already at the first record."; i = 1; }
if (i == num)
{lblmessage.Text = "Already at the last record.";i = num-1; }
lbllastname.Text = pArray[i].surname;
lblfirstname.Text = pArray[i].firstname;
lblsecondname.Text = pArray[i].middlename;
lbldob.Text = pArray[i].dob.ToString();
lblsex.Text = pArray[i].sex;
}
private void btnlast_Click(object sender, EventArgs e)
{
i = num;
}
private void btnfirst_Click(object sender, EventArgs e)
{
i = 0;
}
private void btnnext_Click(object sender, EventArgs e)
{
i++;
}
private void btnprev_Click(object sender, EventArgs e)
{
i--;
}
}
}
和我的班级文件
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Assignment_3
{
class student
{
public string firstname;
public string middlename;
public string surname;
public DateTime dob;
public string sex;
}
}
有人知道哪里出错了吗？我没有错误，但发现文本字段没有用新记录更新，然后当单步通过数组类保存正确数量的记录和字段时，我觉得这将是一件非常明显的事情，我不能把它放在上面.
任何帮助将不胜感激。
