.net IronRuby互操作

IronRuby下载地址http://ironruby.codeplex.com/releases/

1.配置 App.config或Web.config增加如下配置节

<configSections>
        <section name='microsoft.scripting' requirePermission='false' type='Microsoft.Scripting.Hosting.Configuration.Section, Microsoft.Scripting, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'/>
    </configSections>

    <microsoft.scripting>
        <languages>
            <language extensions='.rb' displayName='IronRuby' type='IronRuby.Runtime.RubyContext, IronRuby, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' names='IronRuby;Ruby;rb'/>
        </languages>
    </microsoft.scripting>

2.添加引用IronRuby.dll,IronRuby.Libraries.dll,Microsoft.Scripting.dll

3.控制台HelloWorld示例

 

class Program
    {
        static void Main(string[] args)
        {
            ScriptRuntime runtime = ScriptRuntime.CreateFromConfiguration();
            ScriptEngine engine = runtime.GetEngine("Ruby");
            engine.Execute("puts \"hello world!\"");
            System.Console.ReadKey();
        }
    }

 

 

4.解释IronRuby文件 增加文件Test.rb（存为UTF-8编码格式）, .net下创建Test类并调用实例方法，显示相加结果3。

class Test
    def add a, b
        puts a+b
    end
end

 

class Program
    {
        static void Main(string[] args)
        {
            ScriptRuntime runtime = ScriptRuntime.CreateFromConfiguration();
            ScriptEngine engine = runtime.GetEngine("Ruby");
            ScriptSource source = engine.CreateScriptSourceFromFile("Test.rb", Encoding.UTF8);
            source.Execute();
            var code = String.Format("{0}.new.method :{1}", "Test", "add");
            var action = engine.CreateScriptSourceFromString(code).Execute();
            var result = engine.Operations.Call(action, 1, 2);
            System.Console.ReadKey();
        }
    }

 

在.net 4.0 条件下上例中调用代码可直接替换为

　　dynamic test = engine.Execute("Test.new");
      test.add(1, 2);

参见http://ironruby.net/Documentation/.NET/Hosting 该例中使用了ExcuteFile方法，该方法不支持UTF-8格式文件。

5.IronRuby中调用.net对象，修改Test.rb文件

 

class Test
    def add a, b
        result=a+b
        MessageBox.Show(result.to_s)
    end
end

 

class Program
    {
        static void Main(string[] args)
        {
            ScriptRuntime runtime = ScriptRuntime.CreateFromConfiguration();
            ScriptEngine engine = runtime.GetEngine("Ruby");
            ScriptSource source = engine.CreateScriptSourceFromFile("Test.rb", Encoding.UTF8);
            source.Execute();
            engine.Execute("load_assembly \"System.Windows.Forms\"");
            engine.Execute("include System::Windows::Forms");
            dynamic test = engine.Execute("Test.new");
            test.add(1, 2);
            System.Console.ReadKey();
        }
    }

 

 6.Web调用，新建web项目，根目录新建文件Test.rb

 

class Test
    def sayHello
        HttpContext.Current.Response.Write("<script type='text/javascript'>alert('hello world!');</script>");
    end
end

 

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            ScriptRuntime runtime = ScriptRuntime.CreateFromConfiguration();
            ScriptEngine engine = runtime.GetEngine("Ruby");
            ScriptSource source = engine.CreateScriptSourceFromFile(Server.MapPath("Test.rb"), Encoding.UTF8);
            source.Execute();
            engine.Execute("load_assembly \"System.Web\"");
            engine.Execute("include System::Web");
            dynamic test = engine.Execute("Test.new");
            test.sayHello();
        }
    }
