NP109 Correct or Not

Question

Hi Guys

http://www.c-sharpcorner.com/UploadFile/rmcochran/csharp_memory2B01142006125918PM/csharp_memory2B.aspx

In “C# Heap(ing) Vs Stack(ing) in .NET: Part II” article under the Passing Reference Types heading I have a confusion. Article is saying “we get the value "12345".

In my view we will not get “12345” but “2”. Because ref has not been used in the associated program, please tell me whether I am correct or not.

Thank you

Thank you for your explanation.

The article is in fact correct - you will get 12345 because MyInt is a reference type not a value type. Try it and see: using System; public class MyInt { public int MyValue; } class Test { static void Main() { Test t = new Test(); t.Go(); Console.ReadKey(); } public void Go() { MyInt x = new MyInt(); x.MyValue = 2; DoSomething(x); Console.WriteLine(x.MyValue.ToString()); } public void DoSomething(MyInt pValue) { pValue.MyValue = 12345; } }
