Inheritance with a constructor that takes arguments problem

[aewarnick]

class Inherit : c1
{
 Inherit(){} // calls c1() constructor but not c1(string argument)
//which messes things up.
//How would I call the constructor with an argument in the base class?
}


class c1 : UserControl
{
 public c1(){}
 public c1(string argument)
 {
   // argument is used here and is important!
 }
}

Instead of doing the initialization inside the constructor of the

base class, create a protected or public method in the base

class that does the initialization, and then you can call it in both

the regular constructor and the inheritor's constructor.

 

class Inherit : c1
{
 Inherit()
 {
   base.InitClass("whatever");
 }
}


class c1 : UserControl
{
 public c1(){}
 public c1(string argument)
 {
   InitClass(argument);
 }
 
 protected void InitClass(string argument)
 {
   // Initialize the class with the argument in this sub
 }
}

 

Does this solve your problem?

[aewarnick]

Yes, that will solve my problem. Thanks.

The "correct" way to do what you're after is this:

 

[CS]

class Inherit : c1

{

Inherit() : base("whatever")

{

}

}

 

 

class c1 : UserControl

{

public c1() { }

 

public c1(string argument)

{

// Initialize the class with the argument in this sub

}

}

[/CS]

[aewarnick]

Thanks. Never saw that before. I'll try it out.

It's pretty much the same thing as

 

[CS]

class Inherit extends c1

{

Inherit()

{

super("whatever");

}

}

[/CS]

 

in Java. Only nicer. ;)
