.Net文件*夹*操作

一、文件夹操作

Directory类，DirectoryInfo类.使用using System.IO命名空间

（一）创建文件夹

方法一:

         private string path = @"F:\Text\ceshi";
         private void Create_Click(object sender, EventArgs e)
         {
             Directory.CreateDirectory(path);
         }    

方法二:

         private string path = @"F:\Text\ceshi";
         private void Create_Click(object sender, EventArgs e)
         {
 
             DirectoryInfo CreateDirectory = new DirectoryInfo(path);
             CreateDirectory.Create();
         }

（二）删除文件夹

方法一:

         private string path = @"F:\Text\ceshi";
         private void Delete_Click(object sender, EventArgs e)
         {
             Directory.Delete(path);
         }

方法二:

         private string path = @"F:\Text\ceshi";
         private void Delete_Click(object sender, EventArgs e)
         {
             DirectoryInfo DeleteDircetory = new DirectoryInfo(path);
             DeleteDircetory.Delete();
         }

（三）判断文件夹是否存在

方法一:

         private string path = @"F:\Text\ceshi";
         private void Exist_Click(object sender, EventArgs e)
         {
             bool ifExist = Directory.Exists(path);
             if (ifExist)
             {
                 MessageBox.Show("已存在");
             }
             else
             {
                 MessageBox.Show("不存在");
             }
         }

方法二:

         private string path = @"F:\Text\ceshi";
         private void Exist_Click(object sender, EventArgs e)
         {
             DirectoryInfo ExistDirectory = new DirectoryInfo(path);
             bool ifExist = ExistDirectory.Exists;
             if (ifExist)
             {
                 MessageBox.Show("已存在");
             }
             else
             {
                 MessageBox.Show("不存在");
             }
         }

（四）获取子文件夹

注:获取子文件只能是获取--该路径下的文件夹,其他非文件夹格式获取不到

方法一:

         private void GetDirectory_Click(object sender, EventArgs e)
         {
             string[] Dire =  Directory.GetDirectories(@"F:\Text");//返回的字符串是全路径加文件夹名称(如:"F:\Text\ceshi")
             listBox_GetDiretory.Items.Clear();
             listBox_GetDiretory.Items.AddRange(Dire);
         }

方法二:

         private void GetDirectory_Click(object sender, EventArgs e)
         {
             DirectoryInfo GetDirectory = new DirectoryInfo(@"F:\Text");//只返回文件夹的名字
             DirectoryInfo[] Dire = GetDirectory.GetDirectories();
             listBox_GetDiretory.Items.Clear();
             listBox_GetDiretory.Items.AddRange(Dire);
         }

（五）获取子文件

注:获取子文件只获取--除了文件夹以外其他的文件

方法一:

         private void GetFile_Click(object sender, EventArgs e)
         {
             string[] file = Directory.GetFiles(@"F:\Text");//返回的字符串是全路径加文件名称(如:"F:\Text\ceshi")
             listBox_GetFile.Items.AddRange(file);
         }

方法二:

         private void GetFile_Click(object sender, EventArgs e)
         {
             DirectoryInfo GetFile = new DirectoryInfo(@"F:\Text");//只返回文件名称
             FileInfo[] file = GetFile.GetFiles();
             listBox_GetFile.Items.AddRange(file);
         }

（六）获取文件夹的相关属性

注:日期时间后面Utc代表格列尼日时间

方法一:

         private string path = @"F:\Text\ceshi";
         private void GetInfo_Click(object sender, EventArgs e)
         {
             DateTime CreateTime = Directory.GetCreationTime(path); //获取创建时间
             DateTime AccessTime = Directory.GetLastAccessTime(path);//获取最后访问时间
             DateTime WriteTime = Directory.GetLastWriteTime(path); //获取最后写入的时间
             DirectoryInfo.Text = CreateTime.ToString() + "\n" + AccessTime.ToString() + "\n" + WriteTime.ToString();
         }

方法二:

         private string path = @"F:\Text\ceshi";
         private void GetInfo_Click(object sender, EventArgs e)
         {
             DirectoryInfo DireInfo = new System.IO.DirectoryInfo(path);
             Info.Text = DireInfo.CreationTime.ToString() + "\n" + DireInfo.LastAccessTime.ToString() + "\n" + DireInfo.LastWriteTime.ToString();
         }

（七）修改文件夹的相关属性

方法一:

         private string path = @"F:\Text\ceshi";
         private void SetInfo_Click(object sender, EventArgs e)
         {
             DateTime T = DateTime.Now;
             Directory.SetCreationTime(path, T);
             Directory.SetLastAccessTime(path, T);
             Directory.SetLastWriteTime(path, T);
         }

方法二:

(.............)

（八）移动文件夹(或改名)

注:

Move()或MoveTo():1.路径不同名字相同(相当于--剪切),

　　　　　　　　　　　2.路径不同名字不同(相当于--剪切+重命名),

　　　　　　　　　　　3.路径相同名字不同(相当于--重命名).

且移动是同时将文件夹内的所有对象,移动.

方法一:

         private string path = @"F:\Text\ceshi";
         private void MoveDirectory_Click(object sender, EventArgs e)
         {
             Directory.Move(path, @"F:\Test");
         }

方法二:

         private string path = @"F:\Text\ceshi";
         private void MoveDirectory_Click(object sender, EventArgs e)
         {
             DirectoryInfo MoveDirectory = new DirectoryInfo(path);
             MoveDirectory.MoveTo(@"F:\ceshi2");
         }
