Constructor that takes 1 argument

Question

I have a constructor that takes 2 arguments although I don't know how to write it.

// Home.CS:
var menu = new menu (dt.Rows[0][0].Tostring());

I don't know how to write the second argument in the code above

// Menu.cs
public Menu (string role, string Millitary)
initializeComponet();
Label1.Text = Role;
Label2.Text = Millitary;

What do you expect as end result? Should `Military` be null? — Patrick Hofman, Mar 23 '16 at 10:03
There are too many syntax errors. Consider to copy/paste real code. — Sinatr, Mar 23 '16 at 10:07
`var menu = new Menu(dt.Rows[0][0].Tostring(), string.Empty);` Also rename `Millitary` to `Military`. — Peroxy, Mar 23 '16 at 10:08
Look at constructor overloading: http://stackoverflow.com/questions/5555715/c-sharp-constructors-overloading. Passing in an empty string or null is a pretty rough API. — TEK, Mar 23 '16 at 10:14

If second argument is not required then you can pass any value as

var menu = new Menu (dt.Rows[0][0].Tostring(),string.Empty);

Or if the value of both is to be same then pass same parameter twice as you mentioned in comment

var menu = new Menu (dt.Rows[0][0].Tostring(),dt.Rows[0][0].Tostring());

It is required, it is the same as the first argument – Wael Alsheheli Mar 23 '16 at 10:13
Why not duplicate the first argument then? – Patrick Hofman Mar 23 '16 at 10:13
var menu = new Menu (dt.Rows[0][0].Tostring(),dt.Rows[0][0].Tostring()); Are you expecting this? – M.S. Mar 23 '16 at 10:14
Thank you so much for the help – Wael Alsheheli Mar 23 '16 at 10:21

In side the () so if only one was required it would be (FirstArgument) if 2 are required its (FirstArgument , SecondArgument) etc. using a "," as the seperator
