在delphi中怎么删除文件

try

deletefile(\'文件路径和文件名\');

except

showmessage(\'error\');

end;

直接删的话,就用上面这段代码,已经考虑到了如果当文件不存在时的情况.

如果是要删除到回收站的话用 SHFileOperation（lPSHFILEOPSTRUCT lpFileOp）//这个api函数deletefile，这是我从程序截得一段代码 FileName:string; fos:TSHFileOpStruct; .... FillChar(fos,SizeOf(fos),0); with fos do begin Wnd:=0; wFunc:=FO_DELETE; pFrom:=PChar(FileName); fFlags:=FOF_ALLOWUNDO or FOF_NOCONFIRMATION; end; ShFileOperation(fos);

c\\c++怎样删除文件夹

方便的办法，你可以使用dos命令，在C++里可以用system调用

比如system(\"RMDIR aaa\");

就是删掉aaa这个目录

dos命令可以在cmd里打help回车查看

//这是用vc的方法：bool MyDeleteFile(char * lpszPath) { SHFILEOPSTRUCT FileOp={0}; FileOp.fFlags = FOF_ALLOWUNDO | //允许放回回收站 FOF_NOCONFIRMATION; //不出现确认对话框 FileOp.pFrom = lpszPath; FileOp.pTo = NULL; //一定要是NULL FileOp.wFunc = FO_DELETE; //删除操作 return SHFileOperation(&FileOp) == 0; } void MyDialog::OnButton3() {// MyDeleteFile(\"d:\\\\PID\\0\\0\"); //删除一个文件夹 MyDeleteFile(\"d:\\\\PID.dsp\\0d:\\\\PID.dsw\\0\\0\"); //删除多个文件}void MyDialog::OnButton3() {// MyDeleteFile(\"d:\\\\PID\\0\\0\"); //删除一个文件夹 MyDeleteFile(\"d:\\\\PID.dsp\\0d:\\\\PID.dsw\\0\\0\"); //删除多个文件}
