Why cant I do this without getting the described errors?

Error 1:
Form1.cs(84): 'Outlook_Email_CS.Form1.moApp' denotes a 'field' where a 'class' was expected

Error 2:
Form1.cs(85): An object reference is required for the nonstatic field, method, or property 'Outlook_Email_CS.Form1.moApp'


VB Code:
  1. public class Form1 : System.Windows.Forms.Form
  2.     {
  3.         private System.Windows.Forms.Button button1;
  4.         /// <summary>
  5.         /// Required designer variable.
  6.         /// </summary>
  7.         private Microsoft.Office.Interop.Outlook.Application moApp;
  8.         private System.ComponentModel.Container components = null;
  9.  
  10.         [STAThread]
  11.         static void Main()
  12.         {
  13.             Application.Run(new Form1());
  14.             [color=red]moApp.Quit(); 'Error 1
  15.             moApp = null;[/color] 'Error 2
  16.         }
Thanks
