class parameters by Ref

Jose Saiz

7y1kVisual Basic .NET

I need direction on HOW TO create class in C# that accept parameters by reference,

I am a bit confused with tutorial

https://www.tutorialspoint.com/csharp/csharp_reference_parameters

Back in time Visual Basic I used to create class/functions that accept parameters by Value and by Reference.

ByVal parameter needs to be passed with some value

ByRef parameter needs may be empty or has value

//- Let's assume this my function
public string MyObject(int pParamValue1, ref string pParamValue2)
{
string ResultValue = "Your Result value is";
ResultValue += pParamValue1.ToString();
if (pParamValue2 != null)
{
ResultValue += " By Reference: " + pParamValue;
}
return ResultValue;
}
//- Using the function passing the parameter by value
string GetResult = MyObject(20);
//- Using the function passing the parameter by value and parameter by Ref.
string GetResult = MyObject(20,"Hello World");

Am I in the right path?

Thanks

15. {
17. int x = 10;
19. Console.WriteLine("Variable Value Before Calling the Method: {0}", x);
21. Multiplication(ref x);
23. Console.WriteLine("Variable Value After Calling the Method: {0}", x);
25. Console.WriteLine("Press Enter Key to Exit..");
27. Console.ReadLine();
29. }
31. public static void Multiplication(ref int a)
33. {
35. a *= a;
37. Console.WriteLine("Variable Value Inside the Method: {0}", a);
39. }
41. }
43. }
Please go through above example.

Thank you Madan for your reply, I understand the concept, but what I really trying to accomplish is the necessity of passing the parameter by reference to the function or class.

In order word

How would the function/class behave if the parameter by reference is not passed?

Thanks Again
