Creating instance and calling instance methods

Javonet lets you create instances of any type from .NET Framework DLL. Assuming we have a custom .NET Framework DLL with the following class inside

using System;

namespace TestNamespace
{
	public class TestClass
	{
		public TestClass() { }
		~TestClass()
		{
			Console.WriteLine("Displaying object from .NET destructor message");
		}
		public static int MyStaticField { get; set; }
		public int MyInstanceField { get; set; }

		public static string SayHello(string name)
		{
			return "Hello " + name;
		}

		public int MultiplyByTwo(int arg)
		{
			return arg * 2;
		}

		public T MyGenericMethod<T>(T arg1)
		{
			return arg1;
		}
		public K MyGenericMethodWithTwoTypes<T, K>(T arg1)
		{
			return default(K);
		}

		public void MethodWithRefArg(ref int arg)
		{
			arg = arg + 44;
		}

		public string PassTypeArg(Type myType)
		{
			return myType.ToString();
		}

		public string MethodWithEnumArg(SampleEnum value)
		{
			return value.ToString();
		}
	}
}

To create instance and invoke instance method from this class:

I code in:
// Todo: activate Javonet and add reference to .NET library

// create instance
NObject sampleObject = Javonet.New("TestNamespace.TestClass");

// call instance method
Integer response = sampleObject.invoke("MultiplyByTwo", 50);

// write response to console
System.out.println(response);

Javonet calls are very similar to regular .NET or Java calls, with a little bit of reflection style. Value-type results are automatically converted into .NET Framework DLL types so you can safely assign them to .NET Framework DLL variables. Reference-type results must be assigned to NObject\JObject variable.

Any calls to .NET or Java objects using Javonet can be shortened and simplified using Javonet Fluent interface.
