How to obtain a proper C# string array from a JavaScript function call using Jint

Question

I'm using Jint to evaluate JavaScript within a C# application. My JS returns an array of strings:

return ["blah", "blah", "blah"];

But I'm not sure how to properly use that array once I'm back in C#:

Object result = e.Execute (javaScript).Invoke("jsFunction", answers).ToObject();
string[] resultAsStrings = ???;

Here's what the debugger looks like:

You can just cast the result of ToObject() to an object[] in this case.

Here are the transformations that ToObject() applies when facing a JavaScript value:

• undefined : null
• null : null
• Boolean : bool
• String : string
• Number : double
• Array : object[] with each element itself converted using ToObject()
• Date : DateTime
• Function : Func<JsValue, JsValue[], JsValue>
• RegExp : Regex
• Object : dynamic with all the properties of the object converted using ToObject()

If no type is matching, it throws ArgumentOutOfRangeException
