Hi,

What is the difference between declaring a class as static and delaring
methods as static (class not static)?

Also, when do we use a static constructor?

Declaring the class static forces everything in it to be static and
makes sure there are *no* constructors - not even a private one, or a
parameterless one supplied by the compiler.

When you need to perform some initialisation for the type itself -
typically setting up things like maps which are used elsewhere.

Does that work in C#? Help says static doesn't apply to types.

Hi,

Your explanation on Static class was helpful. But I didn't get the
static constructor part. Let's say I have a class that has a static
constructor, and I attempt to create 2 instances of that type , will there
be 1 instance or 2 instances? I think I am confusing between Singleton and
static here. Can you please give a detailed explanation.
 
Yes it works in C#.
You can declare a class static, and you can also declare a static
constructor.
I think the static class feature was only added in framework v2.

Hi.
1. You can not instanciate a static class.
2. The static constructor is invoked, when the class is loaded.

That would explain why it's not working here :-)
