Constructors

It became apparent the other day that I'd either forgotten some stuff about constructors or never knew it in the first place.

This web page has a good explanation of all the issues: Constructors

For example, what I hadn't really considered is that:

public class MySimpleClass
{
    public MySimpleClass()
    {
    }
}

is converted by the compiler into:

public class MySimpleClass
{
    public MySimpleClass() : base()
    {
    }
}

which makes a bunch of stuff easier to understand.

Similarly 'this' can be used to invoke constructors in the same class:

public class MySimpleClass : MyBaseClass
{
    public MySimpleClass() : this(5)
    {
    }
    public MySimpleClass(int x) : base(x)
    {
    }
}
