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));<span style="white-space:pre"></span>//文件大小            TmpList.Add('FileRec.Name:' + FileRec.Name);<span style="white-space:pre"></span>//文件名            TmpList.Add('FileRec.Attr:' + IntToStr(FileRec.Attr));<span style="white-space:pre"></span>//文件属性            TmpList.Add('FileRec.ExcludeAttr:' + IntToStr(FileRec.ExcludeAttr));<span style="white-space:pre"></span>//未知            TmpList.Add('FileRec.FindHandle:' + IntToStr(FileRec.FindHandle));<span style="white-space:pre"></span>//文件句柄            FileTimeToLocalFileTime(FileRec.FindData.ftCreationTime,FileTime);<span style="white-space:pre"></span>//文件创建时间            FileTimeToSystemTime(FileTime,SysTime);            TmpList.Add('FileRec.FindData.ftCreationTime:' + DateTimeToStr(SystemTimeToDateTime(SysTime)));            FileTimeToLocalFileTime(FileRec.FindData.ftLastAccessTime,FileTime);<span style="white-space:pre"></span>//文件最后 ?? 时间<span style="white-space:pre"></span>            FileTimeToSystemTime(FileTime,SysTime);            TmpList.Add('FileRec.FindData.ftLastAccessTime:' + DateTimeToStr(SystemTimeToDateTime(SysTime)));            FileTimeToLocalFileTime(FileRec.FindData.ftLastWriteTime,FileTime);<span style="white-space:pre"></span>//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));<span style="white-space:pre"></span>//文件大小Hight值            TmpList.Add('FileRec.FindData.nFileSizeLow:' + FloatToStr(FileRec.FindData.nFileSizeLow));            TmpList.Add('FileRec.TimeStamp:' + DateTimeToStr(FileRec.TimeStamp));<span style="white-space:pre"></span>//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      if List.CommaText <> '' then        List.CommaText := List.CommaText + List.Delimiter + TmpList.CommaText      else        List.CommaText := TmpList.CommaText;    end;  finally    FreeAndNil(TmpList);    FreeAndNil(S_FileList);  end;
