反映op_implicit表 [英] Reflect op_implicit table

问题描述

我目前正在寻求建立动态的类型转换器，

I'm currently looking to build dynamic type converter,

例如，我可以很容易做到：

for example, I can easily do :

public struct Tester
{
    public int Hello;

    public static implicit operator int(Tester d)
    {
        return d.Hello;
    }

    public static implicit operator float(Tester d)
    {
        return d.Hello;
    }
}

然后

typeof(Tester).GetMethods()

将返回我隐式转换的MethodInfo。

Will return me implicit cast MethodInfo.

不过，如果我做的：

typeof(int).GetMethods()

这将不返回任何op_implicit

It will not return any op_implicit

我已经看到了，你可以看到表此处，但我想知道是否有可能从框架本身反映了它。

I've seen that you can see the table here , but I was wondering if it's possible to reflect it from the framework itself.

请注意，这不是一个真正的阻塞问题，如果它是不可能的，我会从手工表添加转换器，但我会很明显preFER有这个动态生成的（更清洁，更不容易出错）。

Please note that it's not really a blocking issue, if it's not possible, I'll add converters from the table manually, but I would obviously prefer to have this dynamically built (cleaner and less error prone).

推荐答案

经营者的基本类型没有在框架中定义 - 他们是CLI本身的一部分;他们有自己的特殊说明，基本上是这样。有没有IL参与，没有方法，所以没有一个的MethodInfo 来参考一下。

The operators for the primitive types aren't defined in the framework - they're part of the CLI itself; they have their own special instructions, basically. There's no IL involved, no methods, so nothing for a MethodInfo to refer to.

如果你看一下 System.Decimal ，但是，你会发现运营商是在框架本身实现公正。

If you look at System.Decimal, however, you'll find the operators as that's implemented "just" in the framework itself.

（在略的类似的方法，字符串未声明 + 经营者;对 + C＃中的用途被转换成调用 string.Concat ）

(In a slightly similar way, string doesn't declare a + operator; uses of + within C# are converted to calls to string.Concat.)
