I have an application used by pretty tech-savey people and they want small island of programmability so I've used embedded Iron Python.
我有一个应用程序由漂亮的tech-savey人使用，他们想要小岛的可编程性，所以我使用嵌入式Iron Python。
However, since IronPython 2.0 Eval() doesn't work any more. Specifically I can't both load modules and inject local variables.
但是，由于IronPython 2.0 Eval（）不再起作用。具体来说，我不能同时加载模块和注入局部变量。
There is a work around where I can still call Execute(), print out my answer and listen to StandardOut, but then it comes out as a string and I've lost the type.
有一个工作，我仍然可以调用Execute（），打印我的答案，听取StandardOut，但然后它作为一个字符串出来，我丢失了类型。
Not a disaster for a long, but a huge pain for more complex objects.
长期不是灾难，但对于更复杂的物体来说却是巨大的痛苦。
Does anyone know how to get Eval() working again in 2.0 like it did in 1.x?
有没有人知道如何让Eval（）在2.0中再次像在1.x中那样工作？
Cheers, Jan

Could you be a little more specific about the problem, and maybe provide a code example? The "eval"-style functionality is definitely still present, though as you've noticed, the hosting interface has changed considerably since 1.0.
您能否对问题稍微具体一点，并提供代码示例？ “eval”风格的功能肯定仍然存在，但正如您所注意到的，托管界面自1.0以来发生了很大变化。
This works in beta 5:
这适用于测试版5：
ScriptEngine engine = Python.CreateEngine();
ScriptSource source = engine.CreateScriptSourceFromString("2 + 5", SourceCodeKind.Expression);
int result = source.Execute<int>();
By the way, using the right SourceCodeKind is critical here.
顺便说一下，使用正确的SourceCodeKind在这里至关重要。
