[Mono-winforms-list] Simple tutorial

Hi Paul,

Well I can't understand your question, as namespaces don't talk. :)

Namespaces just separate logically groups of classes. When you are
using classes from a namespace, either by having fully qualified
references or with the short form by means of the using clause, you
need to:

1) guarantee there's no collisions on symbols (names)
2) you reference all the assemblies where the implementation for the
needed classes reside (see that the relationships between namespaces
and assemblies is of the  many-to-many kind).

Example for (1):

using System;
namespace My.System {
  class Console {
    public void DoSomething(string message) {
        Console.WriteLine(message); // <<< problem here method not found
           // as it will assume you are referencing My.System.Console
           // you need to fully qualify as below
        System.Console.WriteLine(message);
    }
  }
}

Example for (2)

using System.Windows.Forms;
using System.Collections.Generic;

namespace whatever {

  class MyForm : Form {

...
    System.Xml.XmlReader xr = new ...
}
}

you need to reference System.dll (where the classes for
System.Collections reside), System.Xml.dll and
System.Windows.Forms.dll;

Hope it helps
