c# - 为什么在嵌套类上调用方法时不调用父类的静态构造函数？

Question

给定以下代码，为什么在“Main”的第一行之后不调用“Outer”的静态构造函数？

namespace StaticTester
{
    class Program
    {
        static void Main( string[] args )
        {
            Outer.Inner.Go();
            Console.WriteLine();

            Outer.Go();

            Console.ReadLine();
        }
    }

    public static partial class Outer
    {
        static Outer()
        {
            Console.Write( "In Outer's static constructor\n" );
        }

        public static void Go()
        {
            Console.Write( "Outer Go\n" );
        }

        public static class Inner
        {
            static Inner()
            {
                Console.Write( "In Inner's static constructor\n" );
            }

            public static void Go()
            {
                Console.Write( "Inner Go\n" );
            }
        }
    }
}

规范的第 10.12 节回答了您的问题，其中指出:

The execution of a static constructor is triggered by the first of the following events to occur within an application domain:

• An instance of the class type is created.

• Any of the static members of the class type are referenced.

因为你没有做这两件事，所以 ctor 没有被执行。
