Cannot implicitly convert type 'object' to 'QUANTUMAUTOMATIONLib.Browse2Class'

I am converting the following code from VB to C#. It works in VB but seems to be have some problem in C#. It is the limitation in C# ? Any expert advice ?


public frmMain()
{
      //
      // Required for Windows Form Designer support
      //
      InitializeComponent();

      //
      // TODO: Add any constructor code after InitializeComponent call
      //
                  
      // Declare global object
      SessionClass objSession;
      QDataAccessClass objDataAccess;
      Browse2Class objBrowser;
                  
      // Get a Session Object.
      objSession = new SessionClass();
                  
      // Get a DataAccess Object.
      objDataAccess = new QDataAccessClass();

      // Get the Browser Object from Session.
      objBrowser = objSession.Browser;   // <-- **** ERROR ****

      // Give the Session Pointer to the DataAccess object.
      objDataAccess.SetSession(objSession);

      }

perhaps you need to cast it: examples

int newInt = (int) stuff [0];
string newString = (string) stuff [1];
Button button2 = (Button) stuff [2];

objBrowser = (Browse2Class)objSession.Browser;

It does not give an error when compiling. But when running the program, it says "Specified cast is not valid". Doesnt seems to be the solution.
