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 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;
