为什么C#没有为变量和方法设计“const”[[副本]

可能重复:
“const correctness” in C#

我怀疑 const 为实现一般语言的简单性而简化了C规范。我们不能将变量引用或方法声明为 常数 就像我们可以用C++?例如。:

const MyObject o = new MyObject();  // Want const cast referenece of MyObject
o.SomeMethod();    // Theoretically legal because SomeMethod is const
o.ChangeStuff();   // Theoretically illegal because ChangeStuff is not const

class MyObject 
{
   public int val = 0;

   public void SomeMethod() const 
   {
      // Do stuff, but can't mutate due to const declaration.
   }

   public void ChangeStuff() 
   {
      // Code mutates this instance.  Can't call with const reference.
      val++;
   }
}
