Question

I’m a beginner in C#.
I want to define a Method that has an input. And the input will be shown in an alert box with this Method.
In other words, the duty of this method is receiving a variable.
Every where that I call this method, the message will be alerted.
I want to know how to define and How to call.

Answer 1

your return type should be “void”

for example:

public void showMsg(string text)
{
    MessageBox.Show(text);
}

you would call your method like this:

showMsg("I can has alert?");
