I am new to .NET, but I think you can define a field in the winform class, instantiate it in the form Load, and define methods that access it:

public class MyForm : System.Windows.Forms.Form
{
   // Define a business object named myBusinessObj
   private MyBusinessClass myBusinessObj;

   private void MyForm_Load(object sender, System.EventArgs e);
   {
      // Instantiate myBusinessObj when the form is loaded
      this.myBusinessObj = new MyBusinessClass();
   }

   private void GetSomeData()
   { 
      this.myBusinessObj.GetSomeRecords()
   }

   private void SaveSomeData()
   { 
      this.myBusinessObj.SaveSomeRecords()
   }
}
