C#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:

1         private string path = @"F:\Text\ceshi";

2         private void Create_Click(object sender, EventArgs e)

3         {

4             Directory.CreateDirectory(path);

5         }    

方法二:

1         private string path = @"F:\Text\ceshi";

2         private void Create_Click(object sender, EventArgs e)

3         {
4            

5             DirectoryInfo CreateDirectory = new DirectoryInfo(path);

6             CreateDirectory.Create();

7         }

 

（二）删除文件夹

方法一:

1         private string path = @"F:\Text\ceshi";

2         private void Delete_Click(object sender, EventArgs e)

3         {

4             Directory.Delete(path);

5         }

 方法二:

1         private string path = @"F:\Text\ceshi";

2         private void Delete_Click(object sender, EventArgs e)

3         {           

4             DirectoryInfo DeleteDircetory = new DirectoryInfo(path);

5             DeleteDircetory.Delete();

6         }

 

（三）判断文件夹是否存在

方法一:

 1         private string path = @"F:\Text\ceshi";

 2         private void Exist_Click(object sender, EventArgs e)

 3         {

 4             bool ifExist = Directory.Exists(path);           

 5             if (ifExist)

 6             {

 7                 MessageBox.Show("已存在");

 8             }

 9             else

10             {

11                 MessageBox.Show("不存在");

12             }

13         }

 

方法二:

 1         private string path = @"F:\Text\ceshi";

 2         private void Exist_Click(object sender, EventArgs e)

 3         {            

 4             DirectoryInfo ExistDirectory = new DirectoryInfo(path);

 5             bool ifExist = ExistDirectory.Exists;

 6             if (ifExist)

 7             {

 8                 MessageBox.Show("已存在");

 9             }

10             else

11             {

12                 MessageBox.Show("不存在");

13             }

14         }

 

（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:

1         private void GetDirectory_Click(object sender, EventArgs e)

2         {

3             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")

4             listBox_GetDiretory.Items.Clear();

5             listBox_GetDiretory.Items.AddRange(Dire);

6         }

 

方法二:

1         private void GetDirectory_Click(object sender, EventArgs e)

2         {           

3             DirectoryInfo GetDirectory = new DirectoryInfo(@"F:\Text");//只返回文件夹的名字

4             DirectoryInfo[] Dire = GetDirectory.GetDirectories();

5             listBox_GetDiretory.Items.Clear();

6             listBox_GetDiretory.Items.AddRange(Dire);

7         }

 

（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:

1         private void GetFile_Click(object sender, EventArgs e)

2         {

3             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")

4             listBox_GetFile.Items.AddRange(file);

5         }

 

方法二:

1         private void GetFile_Click(object sender, EventArgs e)

2         {            

3             DirectoryInfo GetFile = new DirectoryInfo(@"F:\Text");//只返回文件名称

4             FileInfo[] file = GetFile.GetFiles();

5             listBox_GetFile.Items.AddRange(file);

6         }

 

（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:

1         private string path = @"F:\Text\ceshi";

2         private void GetInfo_Click(object sender, EventArgs e)

3         {

4             DateTime CreateTime = Directory.GetCreationTime(path); //获取创建时间

5             DateTime AccessTime = Directory.GetLastAccessTime(path);//获取最后访问时间

6             DateTime WriteTime = Directory.GetLastWriteTime(path); //获取最后写入的时间

7             DirectoryInfo.Text = CreateTime.ToString() + "\n" + AccessTime.ToString() + "\n" + WriteTime.ToString();

8         }

 

方法二:

1         private string path = @"F:\Text\ceshi";

2         private void GetInfo_Click(object sender, EventArgs e)

3         {       

4             DirectoryInfo DireInfo = new System.IO.DirectoryInfo(path);

5             Info.Text = DireInfo.CreationTime.ToString() + "\n" + DireInfo.LastAccessTime.ToString() + "\n" + DireInfo.LastWriteTime.ToString();

6         }

 

（七）修改文件夹的相关属性

方法一:

1         private string path = @"F:\Text\ceshi";

2         private void SetInfo_Click(object sender, EventArgs e)

3         {

4             DateTime T = DateTime.Now;

5             Directory.SetCreationTime(path, T);

6             Directory.SetLastAccessTime(path, T);

7             Directory.SetLastWriteTime(path, T);

8         }

 

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:

1         private string path = @"F:\Text\ceshi";

2         private void MoveDirectory_Click(object sender, EventArgs e)

3         {

4             Directory.Move(path, @"F:\Test");

5         }

方法二:

1         private string path = @"F:\Text\ceshi";

2         private void MoveDirectory_Click(object sender, EventArgs e)

3         {            

4             DirectoryInfo MoveDirectory = new DirectoryInfo(path);

5             MoveDirectory.MoveTo(@"F:\ceshi2");

6         }
