尝试从文本文件输入字符串时被卡住

Question

我正在创建一个程序，该程序允许您解析文本文件中的用户名和密码，然后在数据库中运行它们，以返回用户名、姓氏和部门名称。我已经得到了一个逐行解析文本文件的程序，我已经创建了一个if-else语句来检查该行是否包含"[电子邮件]"或"[密码]"。我想做的是，如果行中包含其中一行，则将整行复制到我可以使用的字符串中。这是我迄今为止的代码，我承认这不是最好的，因为我还在学习。

        }
    }
    private void lister_SelectedIndexChanged(object sender, EventArgs e)
    {
    }
    private void button1_Click(object sender, EventArgs e)
    {
        //populateusername();
        parsetextfile();
    }
    private void browse_Click(object sender, EventArgs e)
    {
        OpenFileDialog fdlg = new OpenFileDialog();
        fdlg.Title = "Open Phishing Textfile";
        fdlg.InitialDirectory = @"c:";
        fdlg.Filter = "TXT files| *.txt";
        fdlg.FilterIndex = 2;
        fdlg.RestoreDirectory = true;
        if (fdlg.ShowDialog() == DialogResult.OK)
        {
            textBox1.Text = fdlg.FileName;
        }
    }
}

这是我试图解析的文本文件：

有人知道这能不能做到吗？如果我说得不太明白，我很抱歉，我对c#还很陌生

Answer 1

据我所知，您已经完成了目标。File.ReadAllLines返回一个字符串数组，每行一个字符串。因此，在代码的这一点上。。。

        foreach (var line in File.ReadAllLines(filepath))
        {
            if (line.Contains("[email]") || line.Contains("[password]"))
            {
                // ** RIGHT HERE, BABY **

line正是您想要的：一个字符串，包含文件中要"处理"的整行内容。
