项目概述
这是一个简单的C# Windows Forms应用程序，展示了如何通过用户界面与文件系统进行交互，并利用.NET框架提供的API来获取文件的元数据，用于浏览和获取程序文件的信息。具体功能包括：
- 浏览程序文件：允许用户通过文件对话框选择一个
.exe文件。 - 获取并显示程序文件信息：一旦选择了文件，应用程序会读取并显示该文件的详细信息，如公司名称、产品名称、语言标志、版本号和版权声明。
- 获取当前程序文件信息：还可以显示当前运行的应用程序本身的详细信息。
- 创建窗体和控件:
- 定义窗体类
Form1并添加各种控件（按钮、文本框、分组框、标签等）。 - 在
InitializeComponent方法中配置每个控件的位置、大小、文本和其他属性。
- 定义窗体类
- 事件绑定:
- 为每个按钮绑定点击事件处理方法。
button1_Click: 打开文件对话框并显示选中的文件路径。button2_Click: 获取并显示所选文件的详细信息。button3_Click: 获取并显示所选的应用程序本身的详细信息。
主要组件及功能
类定义
public class Form1 : System.Windows.Forms.Form
Form1继承自System.Windows.Forms.Form，是整个应用程序的主要窗体类。
控件声明
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: 提供用户交互按钮。
- TextBox: 显示选定文件路径。
- GroupBox: 包含多个标签用于显示文件信息。
- OpenFileDialog: 文件打开对话框，用于让用户选择文件。
- Label: 标签控件，用于显示文本信息。
构造函数
public Form1() {InitializeComponent(); }
- 初始化窗体及其所有子控件。
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资源。
InitializeComponents 方法
此方法由Visual Studio设计器生成，用于初始化窗体上的各个控件及其属性。

事件处理方法
浏览程序文件 (button1_Click)
private void button1_Click(object sender, EventArgs e) {if (openFileDialog1.ShowDialog() == DialogResult.OK){textBox1.Text = openFileDialog1.FileName;} }
- 当点击“浏览程序文件”按钮时，调用
openFileDialog1.ShowDialog()弹出文件对话框。 - 如果用户选择了一个文件并点击了“确定”，则将选中的文件路径赋值给
textBox1.Text。
获取程序文件信息 (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 = "公司名称：" + myInfo.CompanyName;label2.Text = "产品名称：" + myInfo.ProductName;label3.Text = "语言标志：" + myInfo.Language;label4.Text = "版本号：" + myInfo.FileVersion;label5.Text = "版权声明：" + myInfo.LegalCopyright; }
- 从
textBox1中获取文件路径存储在myFileName变量中。 - 如果文件路径为空，则直接返回。
- 使用
Substring和LastIndexOf方法提取文件名，并设置groupBox1的标题。 - 使用
FileVersionInfo.GetVersionInfo方法获取文件的版本信息。 - 将版本信息分别赋值给
label1到label5的Text属性以显示相关信息。
获取本程序文件信息 (button3_Click)
private void button3_Click(object sender, EventArgs e) {groupBox1.Text = "显示本程序文件信息";label1.Text = "公司名称：" + Application.CompanyName;label2.Text = "区域信息：" + Application.CurrentCulture;label3.Text = "语言标志：" + Application.CurrentInputLanguage;label4.Text = "产品名称：" + Application.ProductName;label5.Text = "产品版本：" + Application.ProductVersion; }
- 直接使用
Application类的静态属性获取当前应用程序的版本信息。 - 将这些信息分别赋值给
label1到label5的Text属性以显示相关信息。
