Expander 控件 - 在 C# 中读取 txt 文件（Windows 窗体）

Question

我正在尝试将第二个 .txt 文件 (book2) 添加到 Text Expander 控件中，不幸的是没有成功。

        public Form1()
        {
            InitializeComponent();
            CreateAccordion();
        }
        private void CreateAccordion(string book1)
        {
            Accordion accordion = new Accordion();
            accordion.Size = new Size(400, 350);
            accordion.Left = 10;

            Expander expander1 = new Expander();
            expander1.BorderStyle = BorderStyle.FixedSingle;
            ExpanderHelper.CreateLabelHeader(expander1, "Book1", SystemColors.ActiveBorder);
            CreateContentLabel(expander1, book1, 140);
            accordion.Add(expander1);

            Expander expander2 = new Expander();
            expander2.BorderStyle = BorderStyle.FixedSingle;
            ExpanderHelper.CreateLabelHeader(expander2, "Book2", SystemColors.ActiveBorder);
            CreateContentLabel(expander2, "book2", 120);
            accordion.Add(expander2);
            this.Controls.Add(accordion);
        }

以下代码只读取一个 txt.file。谁能帮帮我？

        private void CreateAccordion()
        {
            ReadTxtFiles();
        }

        private void ReadTxtFiles()
        {
            string path = @"C:\..\..\READBOOKS";
            string[] files = new string[] { "book1.txt", "book2.txt" };

            foreach (string file in files)
            {
                string fullPath = Path.Combine(path, file);
                string booktxt = File.ReadAllText(fullPath);
                string book1 = booktxt;

                CreateAccordion(book1);
            }
        }

I‘m trying to add the second .txt file (book2) into Text Expander control, unfortunately without success.

这背后的主要原因是因为您只传递第一本书中的字符串，您需要传递所有文本。

private void ReadTxtFiles()
        {
            string path = @"C:\..\..\READBOOKS";
            string[] files = new string[] { "book1.txt", "book2.txt" };
            List<string> books = new List<string>();

            foreach (string file in files)
            {
                string fullPath = Path.Combine(path, file);
                string booktxt = File.ReadAllText(fullPath);
                books.Add(booktxt);                                        
            }

            CreateAccordion(books);
        }

更改CreateAccordion的签名：

private void CreateAccordion(List<string) books)
        {
            Accordion accordion = new Accordion();
            accordion.Size = new Size(400, 350);
            accordion.Left = 10;

            Expander expander1 = new Expander();
            expander1.BorderStyle = BorderStyle.FixedSingle;
            ExpanderHelper.CreateLabelHeader(expander1, "Book1", SystemColors.ActiveBorder);
            CreateContentLabel(expander1, books[0], 140);
            accordion.Add(expander1);

            Expander expander2 = new Expander();
            expander2.BorderStyle = BorderStyle.FixedSingle;
            ExpanderHelper.CreateLabelHeader(expander2, "Book2", SystemColors.ActiveBorder);
            CreateContentLabel(expander2, books[1], 120);
            accordion.Add(expander2);
            this.Controls.Add(accordion);
        }

请注意，我在这里访问索引，您可能需要在尝试访问之前检查索引是否存在。还有比这更多的方法，但应该能让你更好地理解如何完成这个。
