读取文本文件并将信息插入到新对象中 [英] Reading a text file and inserting information into a new object

问题描述

  
所以我有一个文本文件，其中包含以下格式的信息，包括名称，电子邮件和电话号码。 Bill Molan，[e-mail]，612-789-7538 
 Greg Hanson，[e-mail]，651-368-4558 
 Zoe Hall，[e-mail] ，952-778-4322 
 Henry Sinn，[e-mail]，651-788-9634 
 Brittany Hudson，[e-mail]，612-756-4486 
  

当我的程序启动时，我想读取这个文件，并把每一行变成一个新的Person（）最终添加到列表中。我想读取每一行，然后使用逗号分隔每个字符串放入Person（）的构造函数，这是一个基本的类：

pre > public PersonEntry（string n，string e，string p）
{
Name = n;
Email = e;
Phone = p;





$ b

我已经做了一些观察，我认为使用streamreader是可行的阅读文本文件，但我不知道从哪里去。

解决方案

您可以使用以下方法：



  
 
字符串行; 
 List listOfPersons = new List（）; 
 
 //读取文件并逐行显示。 
 System.IO.StreamReader file = 
 new System.IO.StreamReader（@c：\yourFile.txt）; （（line = file.ReadLine（））！= null）
 {
 string [] words = line.Split（'，'）; 
 listOfPersons.Add（new Person（words [0]，words [1]，words [2]））; 
} 
 
 file.Close（）; 
 
  




So I have a text file with information in the following format, with the name, email, and phone number.

Bill Molan, [e-mail], 612-789-7538
Greg Hanson, [e-mail], 651-368-4558
Zoe Hall, [e-mail], 952-778-4322
Henry Sinn, [e-mail], 651-788-9634
Brittany Hudson, [e-mail], 612-756-4486

When my program starts, I want to read this file and make each row into a new Person(), which I will eventually add to a list. I am wanting to read each line, and then use the comma to separate each string to put into the constructor of Person(), which is a basic class:

public PersonEntry(string n, string e, string p)
{
    Name = n;
    Email = e;
    Phone = p;
}

I have done some looking and I think that using a streamreader is going to work for reading the text file, but I'm not really sure where to go from here.

解决方案

You can use the following method:

 

    string line;
    List listOfPersons=new List();

    // Read the file and display it line by line.
    System.IO.StreamReader file = 
        new System.IO.StreamReader(@"c:\yourFile.txt");
    while((line = file.ReadLine()) != null)
    {
        string[] words = line.Split(',');
        listOfPersons.Add(new Person(words[0],words[1],words[2]));
    }

    file.Close();
