文件查找记录类型 - TSearchRec - 文件操作(二)

SysUtils单元下的TSearchRec是一个记录类型，主要通过FindFirst, FindNext, and FindClose使用。

接上一篇举例说明TSearchRec常用成员

//sysGetFileList(List,'c:\','*.doc,*.exe');  List通过查找添加多文件  

//sysGetFileList(List,'c:\','*.doc');   List通过查找添加单文件  

procedure sysGetFileList(List: TStrings; SourFile,FileName: string);  

var  

  S_Path: String;  

  TmpList,S_FileList: TStringList;  

  FileRec,SubFileRec: TSearchRec;  

  I: Integer;  

  IsFound: Boolean;  

  SysTime: TSystemTime;  

  FileTime: TFileTime;  

begin  

  S_Path := IncludeTrailingPathDelimiter(Trim(SourFile));     //单元SysUtils中判断末尾是否包含文件夹路径符号'\'，没有的则补全  

  if not DirectoryExists(S_Path) then  

  begin  

    List.Clear;  

    Exit;  

  end;  

  

  S_FileList := TStringList.Create;  

  try  

    S_FileList.CommaText := FileName;  

  

    TmpList := TStringList.Create;  

    for I := 0 to S_FileList.Count - 1 do  

    begin  

      if FindFirst(S_Path + S_FileList[I],faAnyFile,FileRec) = 0 then  

      repeat  

        if ((FileRec.Attr and faDirectory) <> 0) then  

        begin  

          if ((FileRec.Name <> '.') and (FileRec.Name <> '..')) then  

            sysGetFileList(TmpList,IncludeTrailingPathDelimiter(S_Path + FileRec.Name),FileName);  

        end  

        else  

        begin  

          if ((FileRec.Attr and faDirectory) = 0) then  

          begin  

            TmpList.Add(S_Path + FileRec.Name);  

            TmpList.Add('FileRec.Size:' + IntToStr(FileRec.Size));        //文件大小  

            TmpList.Add('FileRec.Name:' + FileRec.Name);          //文件名  

            TmpList.Add('FileRec.Attr:' + IntToStr(FileRec.Attr));        //文件属性  

            TmpList.Add('FileRec.ExcludeAttr:' + IntToStr(FileRec.ExcludeAttr));  //未知  

            TmpList.Add('FileRec.FindHandle:' + IntToStr(FileRec.FindHandle));        //文件句柄  

            FileTimeToLocalFileTime(FileRec.FindData.ftCreationTime,FileTime);        //文件创建时间  

            FileTimeToSystemTime(FileTime,SysTime);  

            TmpList.Add('FileRec.FindData.ftCreationTime:' + DateTimeToStr(SystemTimeToDateTime(SysTime)));  

            FileTimeToLocalFileTime(FileRec.FindData.ftLastAccessTime,FileTime);  //文件最后 ?? 时间     

            FileTimeToSystemTime(FileTime,SysTime);  

            TmpList.Add('FileRec.FindData.ftLastAccessTime:' + DateTimeToStr(SystemTimeToDateTime(SysTime)));  

            FileTimeToLocalFileTime(FileRec.FindData.ftLastWriteTime,FileTime);       //文件最后修改时间  

            FileTimeToSystemTime(FileTime,SysTime);  

            TmpList.Add('FileRec.FindData.ftLastWriteTime:' + DateTimeToStr(SystemTimeToDateTime(SysTime)));  

            TmpList.Add('FileRec.FindData.nFileSizeHigh:' + FloatToStr(FileRec.FindData.nFileSizeHigh));  //文件大小Hight值  

            TmpList.Add('FileRec.FindData.nFileSizeLow:' + FloatToStr(FileRec.FindData.nFileSizeLow));  

  

  

            TmpList.Add('FileRec.TimeStamp:' + DateTimeToStr(FileRec.TimeStamp)); //实际值=文件最后修改时间<pre name="code" class="delphi">  

          end;  

        end;  

      until FindNext(FileRec) <> 0;  

    end;  

    FindClose(FileRec.FindHandle);  

  

    if TmpList.CommaText <> '' then     //空文件夹不添加路径  

    begin

        List.CommaText := List.CommaText + List.Delimiter + TmpList.CommaText  

      else  

        List.CommaText := TmpList.CommaText;
