本文實例講述了C#停止文件讀寫、創立、復制、挪動、刪除的辦法。分享給年夜家供年夜家參考。詳細剖析以下：

1.文件夾創立、挪動、刪除

//創立文件夾
Directory.CreateDirectory(Server.MapPath("a"));
Directory.CreateDirectory(Server.MapPath("b"));
Directory.CreateDirectory(Server.MapPath("c"));
//挪動b到a
Directory.Move(Server.MapPath("b"), Server.MapPath("a//b"));
//刪除c
Directory.Delete(Server.MapPath("c"));

2.文件創立、復制、挪動、刪除

//創立文件
//應用File.Create創立再復制/挪動/刪除時會提醒：
//文件正由另外一過程應用,是以該過程沒法拜訪該文件
//改用 FileStream 獲得 File.Create 
//前往的 System.IO.FileStream再停止封閉就無此成績
FileStream fs;
fs = File.Create(Server.MapPath("a.txt"));
fs.Close();
fs = File.Create(Server.MapPath("b.txt"));
fs.Close();
fs = File.Create(Server.MapPath("c.txt"));
fs.Close();
//復制文件
File.Copy(Server.MapPath("a.txt"),Server.MapPath("a//a.txt"));
//挪動文件
File.Move(Server.MapPath("b.txt"),Server.MapPath("a//b.txt"));
File.Move(Server.MapPath("c.txt"),Server.MapPath("a//c.txt"));
//刪除文件
File.Delete(Server.MapPath("a.txt"));

3.遍歷文件夾中的文件和子文件夾並顯示其屬性

if(Directory.Exists(Server.MapPath("a")))
{
 //一切子文件夾
 foreach(string item inDirectory.GetDirectories(Server.MapPath("a")))
 {
  Response.Write("<b>文件夾：" + item +"</b><br/>");
  DirectoryInfo directoryinfo = new DirectoryInfo(item);
  Response.Write("稱號："+directoryinfo.Name +"<br/>");
  Response.Write("途徑："+directoryinfo.FullName +"<br/>");
  Response.Write("創立時光："+directoryinfo.CreationTime +"<br/>");
  Response.Write("前次拜訪時光："+directoryinfo.LastAccessTime+"<br/>");
  Response.Write("前次修正時光："+directoryinfo.LastWriteTime+"<br/>");
  Response.Write("父文件夾："+directoryinfo.Parent+"<br/>");
  Response.Write("地點根目次："+directoryinfo.Root+"<br/>");
  Response.Write("<br/>");
 }

 //一切子文件
 foreach (string item inDirectory.GetFiles(Server.MapPath("a")))
 {
  Response.Write("<b>文件：" + item +"</b><br/>");
  FileInfo fileinfo = new FileInfo(item);
  Response.Write("稱號：" + fileinfo.Name +"<br/>");
  Response.Write("擴大名：" + fileinfo.Extension+"<br/>");
  Response.Write("途徑：" + fileinfo.FullName+"<br/>");
  Response.Write("年夜小：" + fileinfo.Length+"<br/>");
  Response.Write("創立時光：" + fileinfo.CreationTime+"<br/>");
  Response.Write("前次拜訪時光：" + fileinfo.LastAccessTime+"<br/>");
  Response.Write("前次修正時光：" + fileinfo.LastWriteTime+"<br/>");
  Response.Write("地點文件夾：" + fileinfo.DirectoryName+"<br/>");
  Response.Write("文件屬性：" + fileinfo.Attributes+"<br/>");
  Response.Write("<br/>");
 }
}

4.文件讀寫

if (File.Exists(Server.MapPath("a//a.txt")))
{
 StreamWriter streamwrite = newStreamWriter(Server.MapPath("a//a.txt"));
 streamwrite.WriteLine("木子屋");
 streamwrite.WriteLine("http://www.jb51.net/");
 streamwrite.Write("2008-04-13");
 streamwrite.Close();
 StreamReader streamreader = newStreamReader(Server.MapPath("a//a.txt"));
 Response.Write(streamreader.ReadLine());
 Response.Write(streamreader.ReadToEnd());
 streamreader.Close();
}
