Problém se stringem – .NET – Fórum – Programujte.com

Ahoj mám problém s tímto řádkem: DirectoryInfo^ directoryInfo = gcnew DirectoryInfo (stringDirectory);

kdy se mi program zkompiluje a můžu ho zpustist. Ale kdykoliv se má použít tato část programu, mi to pošle varovnou zprávu a program nefunguje tak, jak by měl.

private: System::Void textBoxDirectoryPlugins_TextChanged(System::Object^  sender, System::EventArgs^  e) {
			 for (int i = 0; i < checkedPlugins->Items->Count; ++i)
			 {
				 checkedPlugins->Items->RemoveAt(i);
			 }
			 String^ stringDirectory = directoryOfPlugins->ToString ();
			 DirectoryInfo^ directoryInfo = gcnew DirectoryInfo (stringDirectory);
			 array<System::IO::FileInfo^>^ arrayMasters = directoryInfo->GetFiles ("*.esm");
			 array<System::IO::FileInfo^>^ arrayPlugins = directoryInfo->GetFiles ("*.esp");
			 for (int i = 0; i < arrayMasters->Length; ++i)
			 {
				 checkedPlugins->Items->Add(arrayMasters[i]->Name);
			 }
			 for (int i = 0; i < arrayPlugins->Length; ++i)
			 {
				 checkedPlugins->Items->Add(arrayPlugins[i]->Name);
