Automatic code generation from a C# class to JavaScript equivalent

Question

I'd like to expose a class I've written in C# down to the javascript equivalent.

for example I have a class like:

// C# class to represent an Appriaser
public class Appraiser
{
    public Appraiser(appraiserId, appraiserName)
    {
         AppraiserId = appraiserId;
         AppraiserName = appraiserName;
    }
    public int AppraiserId { get; set; }
    public string AppraiserName { get; set; }
}

and I would like the ability to automatically generate a version of this class in javascript

// javascript class to represent an Appraiser
function Appraiser(appraiserId, appraiserName) {
    var self = this;
    self.appraiserid= appraiserId;
    self.appraisername= appraisername;
}

Is this possible with JSON.NET or another method?

Answer 1

You could try sharp2Js. You pass it a type and it converts it to a C# string. Use it with a T4template if you want it to output to a js file. For the class in your example, it produces:

Using it with your example:

var str = Castle.Sharp2Js.JsGenerator.
              GenerateJsModelFromTypeWithDescendants(typeof(Appraiser), true, "example");

Outputs:

example = {};

example.Appraiser = function (cons, overrideObj) {
    if (!overrideObj) { overrideObj = { }; }
    if (!cons) { cons = { }; }
    var i, length;
    this.appraiserId = cons.appraiserId;
    this.appraiserName = cons.appraiserName;


    this.$merge = function (mergeObj) {
        if (!mergeObj) { mergeObj = { }; }
        this.appraiserId = mergeObj.appraiserId;
        this.appraiserName = mergeObj.appraiserName;
    }
}

Note: I'm the maintainer of sharp2Js, it's young so not feature-rich yet (any suggestions are welcome) but it may suit your needs for simple uses.

You can try JSIL. It will allow You to transform from .Net IL to JavaScript.
