强制类加载 [英] Forcing class load

问题描述

有没有办法在C＃或.net IL强制具有类型初始化一个类（静态构造函数）来加载自身，而无需访问它的任何参数？

Is there a way in C# or .net IL to force a class that has a type initializer (static constructor) to load itself, without accessing any of its parameters?

假设我有类

public static class LogInitialization {
    static LogInitialization() {
        System.Console.WriteLine("Initialized");
    }
}

有没有办法让这条线来打印？

Is there a way to get this line to print?

请注意这个类是静态的，所以我不能将它实例强制初始化，并且它没有公开的成员，所以我不能访问他们开始吧。

Note that the class is static so I can't instantiate it to force initialization, and it has no public members so I can't access them to start it.

推荐答案

在翻找的CLI规范，我发现了一个参考方法<一href="http://msdn.microsoft.com/en-us/library/system.runtime.compilerservices.runtimehelpers.runclassconstructor.aspx"><$c$c>RuntimeHelpers.RunClassConstructor

Rummaging in the CLI spec, I found a reference to the method RuntimeHelpers.RunClassConstructor

如果一个语言希望提供更严格的行为 - 例如，键入初始化自动触发执行   基类的初始化，在上到下依次 - 那么就可以通过这样做的：

If a language wishes to provide more rigid behavior — e.g., type initialization automatically triggers execution of base class’s initializers, in a top-to-bottom order — then it can do so by either:

  
• 定义隐藏静态字段和code中的每个类的构造函数触及的隐藏静态字段的   基类和/或接口它实现，或
  
• 通过显式调用 System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor   （请参阅分区IV）。
  

• defining hidden static fields and code in each class constructor that touches the hidden static field of its base class and/or interfaces it implements, or
• by making explicit calls to System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor (see Partition IV).
