我是编程新手，需要您的帮助。我正在使用 C# Visual Studio 2010，我需要能够从文件中读取数据并将数据显示到相关的文本框中。文本文件是足球队的列表，我必须显示、编辑、删除和保存文件。我做了一些研究，并使用 YouTube 创建了使用 Stream Readers 的程序，但他们没有做我想让他们做的事情。我了解流式阅读器如何读取数据，但在相关框中逐行显示数据时遇到困难 IE：团队名称、团队经理、团队体育场等。我已经为团队制作了下面列出的课程以及我遇到问题的表单代码。任何帮助将非常感激。
我的班级：使用系统的团队；使用 System.Collections.Generic；使用 System.Linq；使用 System.Text；
