如何引用从 IronRuby 添加到 ScriptScope 的变量？

我正在尝试将变量添加到作用域，然后从我的 ruby 表达式访问该变量。

时间：2019-03-17 标签：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();

Ruby

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

I'm trying to add a Variable to the scope and then access that variable from my ruby expression.

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();

Ruby

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

你们非常接近。只需将 C# 代码的最后两行更改为下一行：

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

此外，虽然我不确定您要实现什么目标，但您可以以更简单的方式使用 C# 中的类：

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();

You were pretty close. Just change the last two lines of your C# code to the next ones:

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

In addition, though I'm not sure what you're trying to achieve, you can use your class from C# in an easier fashion:

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();
