如何引用從IronRuby添加到ScriptScope的變量？

Question

我想向範圍添加一個變量，然後從我的ruby表達式訪問該變量。

C＃

ScriptRuntime runtime = IronRuby.Ruby.CreateRuntime(); 
var scope = runtime.ExecuteFile("C:\\codebase\\Test\\Test2\\Test2\\person2.rb"); 
scope.SetVariable("name", "Scott"); 
dynamic person = scope.Engine.Execute("p = Person.new(name)"); 
person.sayHi(); 

紅寶石

class Person 
    def initialize(name) 
     @name = name.capitalize 
    end 
    def sayHi 
     puts "Hello #{@name}!" 
    end 
end 

Answer 1

你是八九不離十。只是你的C＃代碼的最後兩行更改爲下一個的：

dynamic p = scope.Engine.Execute("Person.new(name)", scope); 
p.sayHi(); 

另外，雖然我不知道你想實現的，你可以使用從C＃類在一個更簡單的方式是什麼：

var engine = Ruby.CreateEngine(); 
var scope = engine.ExecuteFile(@"C:\codebase\Test\Test2\Test2\person2.rb"); 

dynamic globalConstants = engine.Runtime.Globals; 
dynamic person = globalConstants.Person.@new("shay"); 
person.sayHi();
