        static void Main(string[] args)
        {
            string path = @"c:/windows/system32/spider.exe";
            string path1 = @"c:/windows";
            string path2 = @"system32/spider.exe";

//返回目录部分c:/windows/system32
Console.WriteLine(Path.GetDirectoryName(path));

//返回文件名spider.exe
Console.WriteLine(Path.GetFileName(path));

//返回文件扩展名.exe
Console.WriteLine(Path.GetExtension(path));

//返回当前程序集的完整路径
Console.WriteLine(System.Reflection.Assembly.GetExecutingAssembly().Location);

//返回当前目录
Console.WriteLine(Directory.GetCurrentDirectory());

//合并路径,返回c:/windows/system32/spider.exe
Console.WriteLine(Path.Combine(path1, path2));

            //判断目录c:/abc是否存在
            if (Directory.Exists(@"c:/abc") == false)
            {
                //创建目录c:/abc
                Directory.CreateDirectory(@"c:/abc");
            }
            //移动目录c:/abc到c:/a目录下
            Directory.Move(@"c:/abc", @"c:/a/abc");

            //删除空目录c:/abc
            Directory.Delete(@"c:/abc");
            //递归删除目录c:/abc
            Directory.Delete(@"c:/abc",true);

//删除文件c:/abc.txt
File.Delete(@"c:/abc.txt");

//拷贝文件c:/abc.txt到d盘
File.Copy(@"c:/abc.txt",@"d:/abc.txt");

            //移动c:/abc.txt到d盘
            File.Move(@"c:/abc.txt", @"d:/abc.txt");
        }
    }
