C# Directory和DirectoryInfo类(文件目录操作)

对目录操作例子:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.IO;

namespace DirectoryandDirectoryInfo

{

    class Program

    {

        static void Main(string[] args)

        {

            string dirPath = "d:\\dir2";

            string filePath = string.Format("{0}\\{1}", dirPath, "test.txt");

            //判断当前目录是否存在

            if (!Directory.Exists(dirPath))

            {

                //创建目录

                Directory.CreateDirectory(dirPath);

                Console.WriteLine("创建一个目录{0}", dirPath);

            }

            else

            {

                Console.WriteLine("目录{0}已存在", dirPath);

            }

            //实例化文件对象

            FileInfo file = new FileInfo(filePath);

            //判断文件是否存在

            if (!file.Exists)

            {

                //创建文件

                file.Create();

                Console.WriteLine("创建文件{0}",filePath);

            }

            else

            {

                Console.WriteLine("文件{0}已存在", filePath);

            }

            Console.ReadKey();

        }

    }

}
