Inno Setup Loop through files and register each .N

Question

I am creating a setup file using Inno Setup where I need to register unknown number of .net dlls using regasm.exe file. I know that I can use the following code to register .net dll.

[Run]
Filename: "{dotnet20}\RegAsm.exe"; Parameters: /codebase MyDLL.dll; WorkingDir: {app}; StatusMsg: "Registering Controls."; Flags: runminimized

My problem is, there are more than one dlls in the folder and I don't know the name of each dll to be registered. Is there a way where I can loop through the files in the folder and register each one of them without knowing the number of files and their names?

Please help, Thanks

I cannot find any flag which would register them for you e.g. from the [Files] section, so I wrote this script, which should iterate all the *.dll files in the specified folder and for each call the registration tool command line. Please note, that I haven't tested this script, and I'm not sure about the used command line with its parameters, but the basic idea should be there:

[Code]
function RegisterNetLibraries(const Folder: string): Integer;
var
  RegTool: string;
  FindRec: TFindRec;
  ResultCode: Integer;  
begin
  // initialize result to 0 processed files
  Result := 0;
  // expand the path to the registration tool
  RegTool := ExpandConstant('{dotnet20}\RegAsm.exe');
  // check if the registration tool exists; if not then exit...
  if not FileExists(RegTool) then
  begin
    MsgBox('RegAsm.exe not found!' + #13#10 + RegTool, mbError, MB_OK);
    Exit;
  end;
  // if we've found a *.dll file in the specified folder, then...
  if FindFirst(ExpandConstant(Folder + '\*.dll'), FindRec) then
  try
    // repeat loop for every *.dll file in the specified folder
    repeat
      // if the iterated item is not a directory named like Dir.dll
      if FindRec.Attributes and FILE_ATTRIBUTE_DIRECTORY = 0 then
      begin
        // if the execution of the registration tool succeeded, then...        
        if Exec(RegTool, '/codebase ' + Folder + '\' + FindRec.Name, 
          ExpandConstant('{app}'), SW_HIDE, ewWaitUntilTerminated,
          ResultCode)
        then
          // increase the returned processed file count
          Result := Result + 1
        else
          // the execution failed, so let's try to show why
          SysErrorMessage(ResultCode);
      end;
    until
      // when there no next file item, the loop ends
      not FindNext(FindRec);
  finally
    // release the allocated search resources
    FindClose(FindRec);
  end;
end;

procedure CurStepChanged(CurStep: TSetupStep);
var
  Count: Integer;
begin
  // if we are at the post installation step, then...
  if CurStep = ssPostInstall then
  begin
    // the RegisterNetLibraries function returns count of processed files,
    // don't forget that you must pass expanded constant values
    Count := RegisterNetLibraries(ExpandConstant('{app}\Libs'));
    // show how many files have been processed
    MsgBox(IntToStr(Count) + ' libraries was processed...', mbInformation,
      MB_OK);
  end;
end;
