How do I use a message box in C#?

How can I use a message box in C# without 开发者_开发问答a script?

You haven't really specified your target application type, so:

• For a Console application:

  Console.WriteLine("hello world");
  

• For a WinForms/desktop application:

  MessageBox.Show("hello world");
  

• For a web application:

  alert('hello world');
  

  or you could also implement custom dialogs with javascript and jquery.

MessageBox.Show()

have you tried googling?
