C#提供的类库能够轻松实现对文件的操作

    //C#写入/读出文本文件
  string fileName =@"c:I.txt";
  StreamReader sr
= new StreamReader(fileName); string str=sr.ReadLine (); sr.close();
  StreamWriterrw
=File.CreateText(Server.MapPath(".")+"\myText.txt");
  rw.WriteLine(
"写入");
  rw.WriteLine(
"abc");
  rw.WriteLine(
".NET笔记");
  rw.Flush();
  rw.Close();
  
//打开文本文件
  StreamReadersr=File.OpenText(Server.MapPath(".")+"\myText.txt");
  StringBuilderoutput
=newStringBuilder();
  stringrl;
  
while((rl=sr.ReadLine())!=null)
  ...{
  output.Append(rl
+"");
  }
  lblFile.Text
=output.ToString();
  sr.Close();
  
//C#追加文件
  StreamWritersw=File.AppendText(Server.MapPath(".")+"\myText.txt");
  sw.WriteLine(
"追逐理想");
  sw.WriteLine(
"kzlll");
  sw.WriteLine(
".NET笔记");
  sw.Flush();
  sw.Close();
  
//C#拷贝文件
  stringOrignFile,NewFile;
  OrignFile
=Server.MapPath(".")+"\myText.txt";
  NewFile
=Server.MapPath(".")+"\myTextCopy.txt";
  File.Copy(OrignFile,NewFile,
true);
  
//C#删除文件
  stringdelFile=Server.MapPath(".")+"\myTextCopy.txt";
  File.Delete(delFile);
  
//C#移动文件
  stringOrignFile,NewFile;
  OrignFile
=Server.MapPath(".")+"\myText.txt";
  NewFile
=Server.MapPath(".")+"\myTextCopy.txt";
  File.Move(OrignFile,NewFile);
  
//C#创建目录
  
//创建目录c:sixAge
  DirectoryInfod=Directory.CreateDirectory("c:\sixAge");
  
//d1指向c:sixAgesixAge1
  DirectoryInfod1=d.CreateSubdirectory("sixAge1");
  
//d2指向c:sixAgesixAge1sixAge1_1
  DirectoryInfod2=d1.CreateSubdirectory("sixAge1_1");
  
//将当前目录设为c:sixAge
  Directory.SetCurrentDirectory("c:\sixAge");
  
//创建目录c:sixAgesixAge2
  Directory.CreateDirectory("sixAge2");
  
//创建目录c:sixAgesixAge2sixAge2_1
  Directory.CreateDirectory("sixAge2\sixAge2_1");

  但是,在对txt文件读的操作中貌似没问题。因为代码能实现文件的读操作,但是所读txt文件包含中文的时候就以乱码显示。查了半天资料,看似复杂的问题其实很简单就能解决,稍微改动一下即可:

StreamReader sr = new StreamReader(fileName,Encoding.GetEncoding("gb2312"));
