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 :=  to S_FileList.Count -  do
    begin
      if FindFirst(S_Path + S_FileList[I],faAnyFile,FileRec) =  then
      repeat
        if ((FileRec.Attr and faDirectory) <> ) 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) = ) 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) <> ;
    end;
    FindClose(FileRec.FindHandle);  

    if TmpList.CommaText <> '' then     //空文件夹不添加路径
    begin
      if List.CommaText <> '' then
        List.CommaText := List.CommaText + List.Delimiter + TmpList.CommaText
      else
        List.CommaText := TmpList.CommaText;
    end;
  finally
    FreeAndNil(TmpList);
    FreeAndNil(S_FileList);
