MyBase equivalent in C#? and others?

well I get a better response in the Vb.net section hence I posted this here. It's a question that the vb people shuold answer anyways:D

so what is MyBase in C#?I wanna use MyBase.New...
Another q, what's MyClass in C#?

also, if I wanna call an overloaded new constructor from another constructor, how do I do it? (ie, new (blah, blah) )

The MyBase equivalent in C# is base.

You would do constructor chaining like this...

Code:

---

        public class Test
        {
                public Test(): this(1)
                {
                        //...
                }

                public Test(int x)
                {
                        //...
                }
        }

hmm thanks... what is that : this(1) doing in front of the constructor :confused: ?
yeah apparently base "acts" differently from MyBase of VB. You can use MyBase.NEW in vb:( anyways here's how I'm calling the constructor withing another constructor and it apparently works. It this the right way though?:
Public Test()
{
new Text (3);
}


edit:hmm I'm gussing this(1) is calling the constructor, uuh but it's weird because when I do it the stupid Intellisense doesnt show up, but when I use new() it does show up

That doesn't work for me. Try it...

Code:

---

        /* ... Form code... */
        {

                private void Form1_Load(object sender, System.EventArgs e)
                {
                        Test t = new Test();

                        MessageBox.Show(t.X.ToString());
                }
        }

        public class Test
        {
                private int _x;

                public int X
                {
                        get { return _x; }
                }

                public Test()
                {
                        new Test(1);
                }

                public Test(int x)
                {
                        _x = x;
                }
        }

Instead of returning 1 like you would think, it returns 0. That's because

public Test()
{
new Test(1);
}

simple creates a new Test object and it simpley goes away.

The first way is the correct way.

:D :D I look funny trying to program in C/C++ style:D hehe thank you :afrog:

hmm so one more question. Does the constructor chaining occure AFTER you are done with the current constructor?

Code:

---

                public Test() : this(1)
                {
                        System.Diagnostics.Debug.WriteLine("1");
                }

                public Test(int x)
                {
                        System.Diagnostics.Debug.WriteLine("2");
                        _x = x;       
                }

---

Results in :

2
1

So the constructor that is called from the constructor executes first, then the original constructor's code is executed.

hmm interesting. So I'm puzzled, what if I want to do something like this!

public Test()
{
int someNum;
// compute someNum ....

// NOW call the other constructor with the someNum value
// Test (someNum)
}

ok apparently what I asked in the last post isnt possible. But is this possible:
public Test():base (99999)
{}

I want to call this (1) after calling the base constructor. How would I do that?

You can't make two constructor calls. You either deall with the call, pass the call to another overload of your constructor, or pass the call to the base class.

aah :( hehe vb seems to be more flexible in this case... but maybe that's just a bad way of coding :D
