I have a question about our famous MessageBox.Show();, this command is an event, method what would be??

Another question is about instantiating object, in the example below we are taking our login form and creating a variable that will be our object reference = receive object frmLogin.

My question is, can I say that my object would be frmLogin or entra

frmLogin entra = new frmLogin()

entra.show();
c# winforms

  • The MessageBoxis a public class of namespace System.Windows.Forms{};
  • The .Show() is a static method of the Messagebox class that has as the return type a Dialogresult;

You can view this information in Metadata in the Visual Studio IDE by selecting the method or class name and pressing the key F12 (Ir para definições):

In the case:

frmLogin entra = new frmLogin()
entra.Show();

entra is an object that refers to classe parcial frmLogin that has as base a classe pública Form. In this situation the object will be instantiated and then invoked the Method .Show() that has as function display control(Form).
