自动创建文件夹文件的方法

Question

要实现一个自动创建文件夹文件的方法，我目前实现的方法很土，可重用性差，我想请教下大家是如何创建的？

        private string checkfilepath()
        {
            if (!File.Exists(Application.StartupPath + "..\\historyfile\\"+DateTime.Now.Year+"\\"+DateTime.Now.Month+"月\\alarm"+ DateTime.Now.Day+"日.hf"))
            {
                if (!Directory.Exists(Application.StartupPath + "..\\historyfile"))
                    Directory.CreateDirectory(Application.StartupPath + "..\\historyfile");
                if(!Directory.Exists(Application.StartupPath+"..\\historyfile\\"+DateTime.Now.Year))
                    Directory.CreateDirectory(Application.StartupPath+"..\\historyfile\\"+DateTime.Now.Year);
                if (!Directory.Exists(Application.StartupPath + "..\\historyfile\\" + DateTime.Now.Year + "\\" + DateTime.Now.Month + "月"))
                    Directory.CreateDirectory(Application.StartupPath + "..\\historyfile\\" + DateTime.Now.Year + "\\" + DateTime.Now.Month + "月");
                File.Create(Application.StartupPath + "..\\historyfile\\" + DateTime.Now.Year + "\\" + DateTime.Now.Month + "月\\alarm" + DateTime.Now.Day + "日.hf");
            }
            return Application.StartupPath + "..\\historyfile\\" + DateTime.Now.Year + "\\" + DateTime.Now.Month + "月\\alarm" + DateTime.Now.Day + "日.hf";
        }我是这样实现的不知大家是如何实现的？

Answer 1

差不多就这个办法。

不过你这么多目录判断是没必要的，在建立文件的时候，目录不存在会自动创建的。

为了好看点，你可以定义一个string变量来保存路径。

Directory.CreateDirectory 会自动创建所有目录，不需要一个个创建

问题要简单，错误须详细@错误/异常/堆栈信息+操作系统+软件版本+all the context of the issue Hope Helpful | http://www.leoworks.net

简化后如下：

        private string checkfilepath()
        {
            string DirctoryPath, FilePath;
            DirctoryPath = Application.StartupPath + "..\\historyfile\\" + DateTime.Now.Year + "\\" + DateTime.Now.Month + "月";
            FilePath = "alarm" + DateTime.Now.Day + "日.hf";
            if (!File.Exists(DirctoryPath+"\\"+FilePath))
            {
                if (!Directory.Exists(DirctoryPath))
                    Directory.CreateDirectory(DirctoryPath);
               using( File.Create(DirctoryPath + "\\" + FilePath));
            }
            return DirctoryPath + "\\" + FilePath;
        }

还能更简化吗？

你好！

这是我的代码，希望对你有帮助

try
            {
                if (Directory.Exists(textBox5.Text))    //判文件夹是否存在
                {
                    string aaa = "该文件夹已经存在";
                    MessageBox.Show(aaa);
                    return;
                }
                else
                {
                    DirectoryInfo dirinfo = System.IO.Directory.CreateDirectory(textBox5.Text);
                    string aaa = "创建文件夹成功,创建时间为：" + Directory.GetCreationTime(textBox5.Text);
                    MessageBox.Show(aaa);
                }
            }
            catch (Exception ee)
            {
                string aaa = "创建文件夹处理失败！ 失败的原因是：" + ee.ToString();
                MessageBox.Show(aaa);
            }
