C#编程轻松实现对文件的操作技巧

//C#写入/读出文本文件 string fileName =@c:Itxt; StreamReader sr = new StreamReader(fileName); string str=srReadLine (); srclose();StreamWriterrw=FileCreateText(ServerMapPath()+/myTexttxt); rwWriteLine(写入); rwWriteLine(abc); rwWriteLine(NET笔记); rwFlush(); rwClose(); //打开文本文件 StreamReadersr=FileOpenText(ServerMapPath()+/myTexttxt); StringBuilderoutput=newStringBuilder(); stringrl; while((rl=srReadLine())!=null) { outputAppend(rl+); } lblFileText=outputToString(); srClose(); //C#追加文件 StreamWritersw=FileAppendText(ServerMapPath()+/myTexttxt); swWriteLine(追逐理想); swWriteLine(kzlll); swWriteLine(NET笔记); swFlush(); swClose(); //C#拷贝文件 stringOrignFileNewFile; OrignFile=ServerMapPath()+/myTexttxt; NewFile=ServerMapPath()+/myTextCopytxt; FileCopy(OrignFileNewFiletrue); //C#删除文件 stringdelFile=ServerMapPath()+/myTextCopytxt; FileDelete(delFile); //C#移动文件 stringOrignFileNewFile; OrignFile=ServerMapPath()+/myTexttxt; NewFile=ServerMapPath()+/myTextCopytxt; FileMove(OrignFileNewFile); //C#创建目录 //创建目录c:sixAge DirectoryInfod=DirectoryCreateDirectory(c:/sixAge); //d指向c:sixAgesixAge DirectoryInfod=dCreateSubdirectory(sixAge); //d指向c:sixAgesixAgesixAge_ DirectoryInfod=dCreateSubdirectory(sixAge_); //将当前目录设为c:sixAge DirectorySetCurrentDirectory(c:/sixAge); //创建目录c:sixAgesixAge DirectoryCreateDirectory(sixAge); //创建目录c:sixAgesixAgesixAge_ DirectoryCreateDirectory(sixAge/sixAge_);
