zy85_C#中文件夹操作，Path，以及Environment类

1.文件夹的操作

1.1Directory类的部分方法

1.2程序代码

try
{string path = @"D:\01";if (Directory.Exists(path)){string[] dirs = Directory.GetDirectories(path);Console.WriteLine("Child Contents");foreach (string dir in dirs){string[] files = Directory.GetFiles(path);Console.WriteLine("File:");foreach (string file in files)Console.WriteLine(file);}}else{Console.WriteLine("Directory do not exist ");}
}
catch (Exception ex)
{Console.WriteLine(ex.ToString());
}

2.Path

2.1Path类的部分字段和方法

2.2程序代码

static void Main(string[] args)
{Console.WriteLine("操作系统中的路径分隔符："+Path.DirectorySeparatorChar);Console.WriteLine("操作系统中环境变量中的路径分隔符：" + Path.PathSeparator);Console.WriteLine("操作系统中的卷分隔符：" + Path.VolumeSeparatorChar);string pa = @"D:\test.txt";Console.WriteLine("指定路径的文件名：" + Path.GetFileName(pa));Console.WriteLine("指定路径的主文件名：" + Path.GetFileNameWithoutExtension(pa));Console.WriteLine("指定路径的扩展名：" + Path.GetExtension(pa));Console.WriteLine("更改指定路径中的扩展名：" + Path.ChangeExtension(pa,"cx"));Console.WriteLine("返回指定路径：" + Path.GetDirectoryName(pa));Console.WriteLine("合并两个路径字符串：" + Path.Combine(Path.GetDirectoryName(pa), Path.GetFileName(pa)));
}

3.Environment

3.1Environment类

3.2SpecialFolder类

3.3程序代码

static void Main(string[] args)
{Console.WriteLine("程序所在的目录：" + Environment.CurrentDirectory);Console.WriteLine("NetBIOS名称：" + Environment.MachineName);Console.WriteLine("环境定义的换行字符串：" + Environment.NewLine);Console.WriteLine("操作系统的标识符和版本号：" + Environment.OSVersion);Console.WriteLine("处理器数量：" + Environment.ProcessorCount);Console.WriteLine("堆栈跟踪信息：" + Environment.StackTrace);Console.WriteLine("系统所在路径：" + Environment.SystemDirectory);Console.WriteLine("系统启动后经过的毫秒数：" + Environment.TickCount);Console.WriteLine("当前用户关联的网络域名：" + Environment.UserDomainName);Console.WriteLine("当前进程是否在用户交互模式中运行：" + Environment.UserInteractive);Console.WriteLine("启动当前线程的用户：" + Environment.UserName);Console.WriteLine("公共语言运行库的版本号：" + Environment.Version);Exception cc=new Exception("好样的");//Environment.FailFast("程序又出错了");Console.WriteLine("包含当前进程的命令行参数：" + Environment.GetCommandLineArgs());foreach(string cc1 in Environment.GetCommandLineArgs()){Console.WriteLine(cc1);}Console.WriteLine("计算机中所有的逻辑驱动器的名称：" + Environment.GetLogicalDrives);foreach (string cc2 in Environment.GetLogicalDrives()){Console.WriteLine(cc2);}Console.WriteLine("我的文档：" + Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments));Console.WriteLine("Internet Cookies:"+Environment.GetFolderPath(Environment.SpecialFolder.Cookies));
