How Can I Parse and Execute JavaScript Code within C#?

To parse and execute JS in C#, you can use the Windows Script Engines. These engines support both 32-bit and 64-bit environments.

Here's an example of how to use the ScriptEngine class to parse and execute a simple JavaScript expression:

using System;
using System.Runtime.InteropServices;

namespace ParseAndExecuteJS
{
    class Program
    {
        [DllImport("ole32.dll")]
        private static extern int CoInitialize(IntPtr pvReserved);

        private const string JavaScriptEngineCLSID = "{F414C240-6E10-11cf-9B44-00AA004738B1}";

        static void Main(string[] args)
        {
            // Initialize COM.
            CoInitialize(IntPtr.Zero);

            // Create a new JavaScript engine.
            ScriptEngine engine = new ScriptEngine(JavaScriptEngineCLSID);

            // Parse the JavaScript code.
            ParsedScript parsedScript = engine.Parse("1 + 2");

            // Execute the JavaScript code.
            object result = parsedScript.CallMethod("eval");

            // Print the result.
            Console.WriteLine(result);
        }
    }
}

This code will output the result of evaluating the JavaScript expression "1 2", which is 3.

You can also use the ScriptEngine class to parse and execute more complex JavaScript code, such as functions and objects.
