項目概述
這是一個簡單的C# Windows Forms應用程序，展示了如何通過用戶界面與文件系統進行交互，并利用.NET框架提供的API來獲取文件的元數據，用于瀏覽和獲取程序文件的信息。具體功能包括：
- 瀏覽程序文件：允許用戶通過文件對話框選擇一個
.exe文件。 - 獲取并顯示程序文件信息：一旦選擇了文件，應用程序會讀取并顯示該文件的詳細信息，如公司名稱、產品名稱、語言標志、版本號和版權聲明。
- 獲取當前程序文件信息：還可以顯示當前運行的應用程序本身的詳細信息。
- 創建窗體和控件:
- 定義窗體類?
Form1?并添加各種控件（按鈕、文本框、分組框、標簽等）。 - 在?
InitializeComponent?方法中配置每個控件的位置、大小、文本和其他屬性。
- 定義窗體類?
- 事件綁定:
- 為每個按鈕綁定點擊事件處理方法。
button1_Click: 打開文件對話框并顯示選中的文件路徑。button2_Click: 獲取并顯示所選文件的詳細信息。button3_Click: 獲取并顯示所選的應用程序本身的詳細信息。
主要組件及功能
類定義
public class Form1 : System.Windows.Forms.Form
Form1繼承自System.Windows.Forms.Form，是整個應用程序的主要窗體類。
控件聲明
private Button button1; private TextBox textBox1; private GroupBox groupBox1; private OpenFileDialog openFileDialog1; private Button button2; private Label label1; private Label label2; private Label label3; private Label label4; private Label label5; private Label label6; private Button button3;
- Button: 提供用戶交互按鈕。
- TextBox: 顯示選定文件路徑。
- GroupBox: 包含多個標簽用于顯示文件信息。
- OpenFileDialog: 文件打開對話框，用于讓用戶選擇文件。
- Label: 標簽控件，用于顯示文本信息。
構造函數
public Form1() {InitializeComponent(); }
- 初始化窗體及其所有子控件。
Dispose 方法
protected override void Dispose(bool disposing) {if (disposing && components != null){components.Dispose();}base.Dispose(disposing); }
- 清理所有正在使用的資源。
InitializeComponents 方法
此方法由Visual Studio設計器生成，用于初始化窗體上的各個控件及其屬性。

事件處理方法
瀏覽程序文件 (button1_Click)
private void button1_Click(object sender, EventArgs e) {if (openFileDialog1.ShowDialog() == DialogResult.OK){textBox1.Text = openFileDialog1.FileName;} }
- 當點擊“瀏覽程序文件”按鈕時，調用?
openFileDialog1.ShowDialog()?彈出文件對話框。 - 如果用戶選擇了一個文件并點擊了“確定”，則將選中的文件路徑賦值給?
textBox1.Text。
獲取程序文件信息 (button2_Click)
private void button2_Click(object sender, EventArgs e) {string myFileName = textBox1.Text;if (myFileName.Length < 1)return;string shortName = myFileName.Substring(myFileName.LastIndexOf("\\") + 1);groupBox1.Text = shortName + "程序文件信息";FileVersionInfo myInfo = FileVersionInfo.GetVersionInfo(myFileName);label1.Text = "公司名稱：" + myInfo.CompanyName;label2.Text = "產品名稱：" + myInfo.ProductName;label3.Text = "語言標志：" + myInfo.Language;label4.Text = "版本號：" + myInfo.FileVersion;label5.Text = "版權聲明：" + myInfo.LegalCopyright; }
- 從?
textBox1?中獲取文件路徑存儲在?myFileName?變量中。 - 如果文件路徑為空，則直接返回。
- 使用?
Substring?和?LastIndexOf?方法提取文件名，并設置?groupBox1?的標題。 - 使用?
FileVersionInfo.GetVersionInfo?方法獲取文件的版本信息。 - 將版本信息分別賦值給?
label1?到?label5?的?Text?屬性以顯示相關信息。
獲取本程序文件信息 (button3_Click)
private void button3_Click(object sender, EventArgs e) {groupBox1.Text = "顯示本程序文件信息";label1.Text = "公司名稱：" + Application.CompanyName;label2.Text = "區域信息：" + Application.CurrentCulture;label3.Text = "語言標志：" + Application.CurrentInputLanguage;label4.Text = "產品名稱：" + Application.ProductName;label5.Text = "產品版本：" + Application.ProductVersion; }
- ?直接使用?
Application?類的靜態屬性獲取當前應用程序的版本信息。 - 將這些信息分別賦值給?
label1?到?label5?的?Text?屬性以顯示相關信息。
