IronPython call method by name

问题

Is there any way to call method by name and specify arguments without using dynamic? (C#)

UPDATE:

` public class Program { public static void Main(string[] args) { ScriptEngine engine = Python.CreateEngine(); ScriptScope scope = engine.CreateScope();

        engine.ExecuteFile("script.py", scope);

        dynamic calculator = scope.GetVariable("Calculator");
        dynamic calculatorInstance = engine.Operations.CreateInstance(calculator);
        dynamic result = engine.Operations.InvokeMember(calculatorInstance, "sample");

        Console.ReadKey();
    }
}

`

class Calculator: def sample(self): return 'test'

That works great

回答1:

You can use the ObjectOperations class to perform dynamic operations, and you can get an instance of it from a ScriptEngine instance:

ScriptEngine engine = ...;
object result = engine.Operations.InvokeMember(o, "foo", 1, 2, "3");

回答2:

Open Source Impromptu-Interface (can be found in nuget) has a bunch of methods for doing reflection-like invocation on any dynamic object, python, ruby, c#, etc, as it uses the dlr c# binder code.

 Impromptu.InvokeMember(o, "foo", 1, 2, "3")

But in this case, JeffHardy's answer is best, since you are already working with a script engine.
