delphi 目录操作函数

简单实用的复制整个目录的方法

function CopyDirectory(const Hwd : LongWord; const SourcePath, DestPath : string): SmallInt;
var
OpStruc: TSHFileOpStruct;
frombuf, tobuf: Array [0..128] of Char;
Begin
Result := -1;
FillChar( frombuf, Sizeof(frombuf), 0 );
FillChar( tobuf, Sizeof(tobuf), 0 );
StrPCopy( frombuf, SourcePath);
StrPCopy( tobuf, DestPath);
With OpStruc DO Begin
Wnd:= Hwd;
wFunc:= FO_COPY;
pFrom:= @frombuf;
pTo:=@tobuf;
fFlags:= FOF_NOCONFIRMATION or FOF_RENAMEONCOLLISION;
fAnyOperationsAborted:= False;
hNameMappings:= Nil;
lpszProgressTitle:= Nil;
end;
if ShFileOperation(OpStruc) = 0 then
Result := 0;
end;

Function Copydirectory(Source:string;pDirectory:string;pFilter:string):boolean;
//目录拷贝source :源目录 directory:目标目录 pFilter:文件类型筛选'/*.*'或'/*.???'
var
OpStruc: TSHFileOpStruct;
frombuf, tobuf: Array [0..128] of Char;
Begin
FillChar( frombuf, Sizeof(frombuf), 0 );
FillChar( tobuf, Sizeof(tobuf), 0 );
StrPCopy(frombuf, Source+pFilter);
StrPCopy( tobuf, pdirectory);
if not directoryexists(pdirectory) then
if not createdir(pdirectory) then
begin
showmessage('不能创建目录'+pdirectory+chr(13)+chr(10)+'或无该目录权限');
exit;
end;
With OpStruc DO Begin
Wnd:= 0;
wFunc:= FO_Copy;
pFrom:= @frombuf;
pTo:=@tobuf;
fFlags:= FOF_NOCONFIRMATION or FOF_RENAMEONCOLLISION or fof_filesonly;
fAnyOperationsAborted:= false;
hNameMappings:= Nil;
lpszProgressTitle:= Nil;
end;
try
ShFileOperation(OpStruc );
CopyDirectory:=true;
except
CopyDirectory:=false;
exit;
end;

end;

为了能拷贝目录下带有子目录的情况，先定义一个辅助的拷贝函数，
它是递归执行的，直到把目录下的所有文件和子目录都拷贝完。

---- 1.1拷贝目录的递归辅助函数：DoCopyDir

function DoCopyDir(sDirName:String;
sToDirName:String):Boolean;
var
hFindFile:Cardinal;
t,tfile:String;
sCurDir:String[255];
FindFileData:WIN32_FIND_DATA;
begin
//先保存当前目录
sCurDir:=GetCurrentDir;
ChDir(sDirName);
hFindFile:=FindFirstFile('*.*',FindFileData);
if hFindFile< >INVALID_HANDLE_VALUE then
begin
if not DirectoryExists(sToDirName) then
ForceDirectories(sToDirName);
repeat
tfile:=FindFileData.cFileName;
if (tfile='.') or (tfile='..') then
Continue;
if FindFileData.dwFileAttributes=
FILE_ATTRIBUTE_DIRECTORY then
begin
t:=sToDirName+'/'+tfile;
if not DirectoryExists(t) then
ForceDirectories(t);
if sDirName[Length(sDirName)]< >'/' then
DoCopyDir(sDirName+'/'+tfile,t)
else
DoCopyDir(sDirName+tfile,sToDirName+tfile);
end
else
begin
t:=sToDirName+'/'+tFile;
CopyFile(PChar(tfile),PChar(t),True);
end;
until FindNextFile(hFindFile,FindFileData)=false;
FindClose(hFindFile);
end
else
begin
ChDir(sCurDir);
result:=false;
exit;
end;
//回到原来的目录下
ChDir(sCurDir);
result:=true;
end;

---- 1.2拷贝目录的函数：CopyDir

function CopyDir(sDirName:String;
sToDirName:string):Boolean;
begin
if Length(sDirName)< =0 then
exit;
//拷贝...
Result:=DoCopyDir(sDirName,sToDirName);
end;
