颤抖吧骚年！！！

关于Edge.js 这里做些介绍：

Edge.js allows you to run Node.js and .NET code in one process on Windows, MacOS, and Linux.

You can call .NET functions from Node.js and Node.js functions from .NET. Edge.js takes care of marshalling data between CLR and V8. Edge.js also reconciles threading models of single threaded V8 and multi-threaded CLR. Edge.js ensures correct lifetime of objects on V8 and CLR heaps. The CLR code can be pre-compiled or specified as C\#, F\#, Python, or PowerShell source: Edge.js can compile CLR scripts at runtime. Edge can be extended to support other CLR languages or DSLs.

[![Edge.js interop model][]][Edge.js interop model]

Edge.js provides an asynchronous, in-process mechanism for interoperability between Node.js and .NET. You can use this mechanism to:

*  script Node.js from a .NET application (console app, ASP.NET, etc.)
 *  script C\# from a Node.js application on Windows, MacOS, and Linux
 *  access MS SQL from Node.js using ADO.NET [more...][]  
    
 *  use CLR multi-threading from Node.js for CPU intensive work [more...][more... 1]  
    
 *  write native extensions to Node.js in C\# instead of C/C++  
    
 *  integrate existing .NET components into Node.js applications

内在运行机制，请看这篇文章： [http://tech.ddvip.com/2013-09/1379955885203202.html][http_tech.ddvip.com_2013-09_1379955885203202.html]

另外，在c\#中执行node.js可以用EdgeJs库，Nuget地址：[http://www.nuget.org/packages?q=Edge.js][http_www.nuget.org_packages_q_Edge.js]

using EdgeJs;
    
    var func = Edge.Func(@"
        return function (data, cb) {
            cb(null, 'Node.js ' + process.version + ' welcomes ' + data);
        }
    ");
    
    Console.WriteLine(await func(".NET"));
