                DateTime time = info.CreationTime;
                label1.Text = time.ToString();
    
                //Exists 目录存在值
                bool b = info.Exists;
                label2.Text = b.ToString();

                string str = info.Extension;
                label3.Text = str;
    
                //获取完整名称(路径名称+文件名称+扩展名)
                string name = info.FullName;
                label4.Text = name;
                //获取文件名称

                //父级文件名称
                string str3 = info.Parent.ToString();
                label6.Text = str3;
                //获取根目录

**2.方法**

///DirectoryInfo方法部分
                DirectoryInfo info1 = new DirectoryInfo(@"E:\C#基础\2019.06.27\01_DirectoryInfo 类");
                //创建同级一个文件夹目录
                info1.Create();
                info1.CreateSubdirectory(@"son\small");
    
                //删除small
                info1 = new DirectoryInfo(@"E:\C#基础\2019.06.27\01_DirectoryInfo 类\son\small");
                info1.Delete();
                //GetDirectories() 子目录的列表
                DirectoryInfo info2 = new DirectoryInfo(@"E:\C#基础");
                DirectoryInfo[] list = info2.GetDirectories();
                for (int i = 0; i < list.Length; i++)
                {
                    listBox1.Items.Add(list[i].FullName);
                }
                info2.GetFiles();
