如何从文本文件中验证用户名和密码?|Winforms C# [英] How to validate username and password from text file? | Winforms C#

问题描述

首先我制作了 textbox1(for username)、textbox2(for password) 和 button1(check).之后:

First I made textbox1(for username) , textbox2(for password) and button1(check). After:

private void button1_Click(object sender, EventArgs e)
{
    FileStream fs = new FileStream(@"D:\C#\test.txt", FileMode.Open, FileAccess.Read, FileShare.None);
    StreamReader sr = new StreamReader(fs);
}

我想从 test.txt 的第一行检查用户名(等于在 textbox1 中从我添加的文本)和第二行的密码.

I want to check username from the first line of test.txt (equals like added from me text in textbox1) and password from the second line.

抱歉我的英语不好.

推荐答案

你可以试试这样的:

private void button1_Click(object sender, EventArgs e){
     string[] lines = System.IO.File.ReadAllLines(@"D:\C#\test.txt");
     String username = lines[0];
     String password = lines[1];
}

但是，这不是存储用户名和密码的好方法.我假设你只是在测试一些东西.

However, it's not a very good way to store your usernames and passwords. I'm assuming you're just testing something out.
