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 }
