  Hello,

  I am using VS 2022 C# .NET Framework 4.8. I am getting an error saying **System.NullReferenceException: ‘Object reference not set to an instance of an object.’

  tabSetup was null.**
  
  while setting Index OR checking Selected Index in switch{}

  tabSetup.SelectedIndex=1;
                  switch (tabSetup.SelectedIndex){}

  Please help. Thanks and Regards
  
  Note: I am not getting this Exception using VB.Net
