IronPython 和实体框架
可能是非常简单的问题，但我是 IronPython 的新手。我想使用 IronPython 来抓取我传递给它的实体，但是当我尝试使用任何扩展方法时，它正如预期的那样崩溃了。如何在 IronPython 中遍历 POCO？
delegate bool EvaluateRule(MyEntity entity);
//Keep in mind this is just to test, no actual value provided
string expression = @"entity.Flags.FirstOrDefault() == null";
MyEntity entity = new MyEntity();
PythonEngine engine = new PythonEngine();
EvaluateRule rule = engine.CreateLambda<EvaluateRule>(expression);
bool result = rule.Invoke(entity);
我得到以下信息： 'EntityCollection[MyEntity]' 对象没有属性 'FirstOrDefault'
提前致谢！
Possibly really simple question, but I'm new to IronPython. I would like use IronPython to crawl an entity I pass to it, but when I try to use any extension methods, it, as sort of expected, blows up. How do I traverse my POCOs in IronPython?
delegate bool EvaluateRule(MyEntity entity);
//Keep in mind this is just to test, no actual value provided
string expression = @"entity.Flags.FirstOrDefault() == null";
MyEntity entity = new MyEntity();
PythonEngine engine = new PythonEngine();
EvaluateRule rule = engine.CreateLambda<EvaluateRule>(expression);
bool result = rule.Invoke(entity);
I get the following: 'EntityCollection[MyEntity]' object has no attribute 'FirstOrDefault'
Thanks in advance!

您可以将扩展方法作为常规静态方法调用：
You can call the extension methods as regular static methods:
