When Is a Static Constructor Called?

You cannot dictate when a static constructor will be called and you can’t call it directly.
More specifically, a static constructor will be called just before you do one of the following:
  • Create an instance of the type
  • Access any static data in the type
  • Start executing Main method (in the same class as the static constructor)
If we have the following implementation in the Dog class:
1
2
3
4
5
6
7
8
9
10
11
12
public Dog(string name)
{
    Console.WriteLine("Dog constructor");
    Name = name;
}
 
public static string Motto = "Wag all the time";
 
static Dog()
{
    Console.WriteLine("Static Dog constructor");
}
And we create a Dog instance:
1
2
3
Console.WriteLine("Here 1");
Dog d1 = new Dog("Kirby");
Console.WriteLine("Here 2");
We get this output (static constructor called before object instantiation):

Or if we access static data:
1
2
3
Console.WriteLine("Here 1");
string s = Dog.Motto;
Console.WriteLine("Here 2");


The output is (static constructor called before accessing static data):
