Re: [Mono-list] Keyword this or base expected(CS1018)
Rob,
Can you give the details of:
- The base class (namespace, name and preferably, also the constructors)
- What you intend to do in your sub-class, if non-classified.
We may be able to help you better...
Having said that, Gennady's example would be the perfect starting
point for you to pickup.
Cheers,
Gaurav

Re: [Mono-list] Keyword this or base expected(CS1018)
of course this wont compile, since you class needs to be deriving from a
class which we will consider a base that has a constructor that takes your
type of arguments:
so to correct the below should look like this:
class MyBase {
public MyBase (Glade.XML gxml, Database database) {
// rest of your construction logic goes here
}
class MyClass : MyBase {
public MyClass (Glade.XML gxml, Database database)
: base(gxml, database) {
// rest of your construction logic goes here
}
hope this helps.

Re: [Mono-list] Keyword this or base expected(CS1018)
in constructor of your class:
class MyClass {
public MyClass(Glade.XML gxml, Database database)
: base(gxml, database) {
// rest of your construction logic goes here
}
you base class needs to be ready for the case if null objects were passed
and react accordingly.

Re: [Mono-list] Keyword this or base expected(CS1018)
OK, so how do I pass args to the base class?
I thought:
MyClass my_class = new MyClass(gxml, database);
would pass gxml and database to the base class of MyClass?

Re: [Mono-list] Keyword this or base expected(CS1018)
This is wrong.
While calling the contructor, the gxml and database are undefined. If
you be appropriate to call as:
public MyClass(): base(null, null)
{
...
}
or better still:
public MyClass(): base( (Glade.XML) null, (Database) null )
{
...
}
Use the latter option if there are more than one overloaded
consturctor in the base class that can make up for BaseClass(null,
null).
NB: I have assumed that Glade.XML is not enum.
