Answer 1

1. This is the best way to transfer data from one form to another, On the LoginForm.cs write like this:

   ex.UserName = txtUserName.text;    
   Password=txtPassword.text;    
   MainForm mainForm = new MainForm(UserName,Password);    
   this.Hide(); 
   
   mainForm.Show();
   

2. In the MainForm.cs edit the

   public MainForm () { }

like this:

public MainForm(string userName,string password){
}
