FileCopy
//- This function will copy files.
DeleteFile
//- This function will delete files.
ListFilesInDirectory
//- This function return a list (TStringList) of files in specified folder.

删除文件夹下所有文件，清空文件夹

var
  FileList : TStringList;
  filesfrom, filepath : string;
  ISEMPTY, i : integer;
begin

filesfrom:= ReqList.Values['DocPath'];
FileList:= TStringList.Create;

try

 ListFilesInDirectory(filesfrom, '*.*', false, FileList);
 ISEMPTY:= FileList.Count;

 if ISEMPTY > 0 then
  for i:= 0 to FileList.Count - 1 do begin
    filepath:= FileList.Strings[i];
    DeleteFile(filepath);
  end;

finally
 FileList.free;

end;

Object Pascal语言参考

//Pos 函数 在字符串中搜索子串 
if POS('软','软件工具')>0 then 1
