Directory picker dialog???

Hi, Does any body know how to display a directory picker dialog in CSharp, I have seen many sample but they are so complex for a simple directory picker dialog, is there any simple directory picker sample. I have a very siple directory picker sample written using shell in win32, can it be used in C-sharp if yes how? static BOOL BrowseForDirectory(HWND hWnd, LPTSTR pSelectedPath, LPCTSTR pPrompt) { BOOL result = FALSE; // Assume failure LPMALLOC pMalloc; // Get's the Shell's default allocator if (::SHGetMalloc(&pMalloc) == NOERROR) { BROWSEINFO bi; TCHAR pszBuffer[MAX_PATH]; LPITEMIDLIST pidl; bi.hwndOwner = hWnd; bi.pidlRoot = NULL; bi.pszDisplayName = pszBuffer; bi.lpszTitle = ; bi.ulFlags = BIF_RETURNFSANCESTORS | BIF_RETURNONLYFSDIRS; bi.lpfn = NULL; bi.lParam = 0; if ((pidl = ::SHBrowseForFolder(&bi)) != NULL) { //get path from id if (::SHGetPathFromIDList(pidl, pszBuffer)) { _tcscpy(pSelectedPath, pszBuffer); result = TRUE; } // Free the PIDL allocated by SHBrowseForFolder pMalloc->Free(pidl); } // Release the shell's allocator pMalloc->Release(); } return result; }
