如何使用 C# 解析文本文件? [英] How do I parse a text file using C#?

问题描述

我想制作一个 Windows 窗体应用程序，它将读取文本文件并将文本文件的字段放入文本框中.

I'd like to make a Windows Forms application that will read in a text file and put the fields of the text file into textboxes.

文本文件格式示例:

Name;Surname;Birthday;Address

Name;Surname;Birthday;Address

Winforms

Name: textboxname

Surname: textboxsurname

Birthday: textboxbirth

Address: textboxaddress

我还希望这个 Winforms 应用程序有一个 Next 和 Back 按钮，以便它可以循环浏览记录.

I also want this Winforms application to have a Next and Back button so it can cycle through the records.

我不知道如何在 C# 中执行此操作.我从哪里开始?

I don't know how to do this in C#. Where do I start?

推荐答案

在一个简单的形式中，你逐行读取文件，在 ; 上拆分每一行并使用值:

In a simple form, you read the file line by line, split each line on ; and use the values:

// open the file in a way so that we can read it line by line
using (Stream fileStream = File.Open("path-to-file", FileMode.Open))
using (StreamReader reader = new StreamReader(fileStream))
{
    string line = null;
    do
    {
        // get the next line from the file
        line = reader.ReadLine();
        if (line == null)
        {
            // there are no more lines; break out of the loop
            break;
        }

        // split the line on each semicolon character
        string[] parts = line.Split(';');
        // now the array contains values as such:
        // "Name" in parts[0] 
        // "Surname" in parts[1] 
        // "Birthday" in parts[2] 
        // "Address" in parts[3] 

    } while (true);
}

此外，请查看 CSVReader，这是一个有助于处理此类文件的库.
