boolb = Convert.ToBoolean(a); Console.WriteLine(b); 但是很好奇Convert.ToBoolean()方法到底是怎么实现的,它有多个重载,string啊,object啊等等。于是使用IL DASM以为能看到点东西,结果只看到下面这些,也是直接调用Convet方法的。 .methodprivatehidebysig instancevoidTest() cil managed ...

But new Boolean(str) is an object. It has it's own unique memory address and it can hold internal state that is unique to it. This means it can't just hold a reference to an immutable singleton instance. Every call to new Boolean(str) instantiates an entire new Boolean() object....
