i create a dll with C# for delete folder with files and sub folders in FTP
but when i want call to that with NSIS i see the message:




this is my NSIS Code:

XPStyle on

Var Ftp_Address
Var Ftp_Username
Var Ftp_Password
Var Ftp_FolderName

Section

StrCpy $Ftp_Address "FTP.ADDRESS.COM" #	$Ftp_Address
StrCpy $Ftp_Username "USERNAME" #		$Ftp_Username
StrCpy $Ftp_Password "PASSWORD" #	$Ftp_Password
StrCpy $Ftp_FolderName "FOLDER NAME_YOU_WANT_DELETE_THAT" #	$Ftp_FolderName

  InitPluginsDir
  SetOutPath $PLUGINSDIR
  File "DLL\*.*"

CLR::Call /NOUNLOAD "FTPCityToolkit.dll" "FTPCityToolkit.DeleteFolderRecursively" "DeleteFtpFolder" 4 "$Ftp_Address" "$Ftp_Username" "$Ftp_Password" "$Ftp_FolderName"
Pop $0
CLR::Destroy

SectionEnd

Also This is the FTPCityToolkit.dll SourceCode C#:

using Limilabs.FTP.Client;


namespace FTPCityToolkit
{
    public class DeleteFolderRecursively
    {
         public void DeleteFtpFolder(string FTPServerName, string FTPUsername, string FTPPassWord, string FTPRootFolderName)
         {
            using (Ftp client = new Ftp())
            {
               client.Connect(FTPServerName);
               client.Login(FTPUsername, FTPPassWord);
               client.DeleteFolderRecursively(FTPRootFolderName);
               client.Close();
            }
         }
    }
}
