Reggie:
You don't need to instantiate the class to initialize its static
members. You just need to use some of its members in your code. The
static constructor is called when the class is loaded and it will be
loaded only if it's needed by your call.
Here is a small sample that initializes a seed using the Random
class. If you comment the DoSomething() method call in Main, it won't
load StaticClass nor execute its static constructor.
using System;
namespace DotNetList.FedeR
{
class StaticClass
{
static float seed;
static StaticClass()
{
Console.WriteLine("StaticClass Initializing");
Random r = new Random();
seed = r.Next();
}
public static void DoSomething()
{
Console.WriteLine("DoingSomething: Seed="+seed);
}
}
class myApp
{
static void Main()
{
Console.WriteLine("Entering Main");
// If you comment this line, constructor won't
be called
StaticClass.DoSomething();
}
}
}
