问题描述
我使用System.Reflection.Emit有一段时间了，并发现它（谁不？）那样痛苦的错误倾向。
I'm using System.Reflection.Emit for a while now, and find it (who don't?) as painful as bug prone.
你知道，如果周围有白细胞介素生成一个很好的包装，这东西我可以靠发射IL在一个更安全和更容易的方式不是直接与SRE玩？
Do you know if there is a good wrapper around the IL Generator, something that I can rely on to emit IL in a more safe and easier manner than with playing directly with SRE?
编辑：
我知道，操纵EX pression树是明确更容易，不是直接发射IL更安全，但也有一些限制，现在。我无法创建code集团，利用循环，声明和几个当地人，等等。我们需要等到.NET 4中出来的工作：）
I know that manipulating expression trees is definitively easier and safer than emitting IL directly, but they also have some constraints right now. I can't create code blocs, use loops, declare and work with several locals, etc. We need to wait until .NET 4 comes out :)
此外，我处理与已经依赖于SRE一个code基地。
Moreover, I'm dealing with a code base which already relies on SRE.
显然，的ILGenerator尽我所需要的。但是我操作的时候它会AP preciate更多的援助。当我指的是一个的ILGenerator包装，它仍保持在pretty的较低水平，我想一些东西，可以提供类似的方法：
Obviously, ILGenerator do everything I need. But I would appreciate more assistance when manipulating it. When I'm referring to a ILGenerator wrapper, which remains at a pretty low level, I think about something which could provide methods like:
// Performs a virtual or direct call on the method, depending if it is a
// virtual or a static one.
Call(MethodInfo methodInfo)
// Pushes the default value of the type on the stack, then emit
// the Ret opcode.
ReturnDefault(Type type)
// Test the object type to emit the corresponding push
// opcode (Ldstr, Ldc_I*, Ldc_R*, etc.)
LoadConstant(object o)
这真的很幼稚3的例子，但它可能是足以证明我的期望。我们可以看到，作为一组扩展方法，但它可能是不错的条件语句的支持和循环像的。事实上，RunSharp是pretty的接近，我想要什么，但它抽象化的ILGenerator太多，不公开其所有功能。
It's really 3 naive examples, but it could be enough to demonstrate what I expect. We can see that as a set of extension methods, but it could be nice to have support for conditional statements and loops like in RunSharp. In fact, RunSharp is pretty close that what I want, but it abstracts the ILGenerator too much and doesn't expose all its functionality.
我不记得在哪里，但我已经看到了这样的帮手一个开源项目。
I can't remember where, but I already saw such an helper in an open source project.
推荐答案
如果您使用的是.NET 3.5，您可能会发现使用防爆pression树更加合理。这完全取决于你在做什么 - 它仍然可以是相当痛苦的 - 但它肯定另一种选择要知道
If you're using .NET 3.5, you may find using Expression Trees to be more reasonable. It entirely depends on what you're doing - and it can still be quite painful - but it's certainly another option to be aware of.
