How to Call a class

Shohibul Jalal

10y1.1kVisual Basic .NET

i have built a small program, but i have problem when i want to call class to Main .

here is the code :

class Operation
{
public static int[,] addition(int x, int y, int z, int c)
{

//some of my code

}

I want to call it into main and show all off the value inside that class. Could you help me to solve this

Hi Shohibul,
Write your class like below format
public class Operation
{
public static int[,] addition(int x, int y, int z, int c)
{
int[,] arr = new int[1, 1];
//some of my code
return arr;
}
}
now call in main method like below,
class Program
{
static void Main(string[] args)
{
var abc = Operation.addition(1, 2, 3, 4);
}
}

Hi,
Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.
I copy this statement from MSDN using this link
https://msdn.microsoft.com/en-IN/library/ms173121.aspx.
private is not a default access modifier for class in C#.
So within same assembly, without access modifier class can be instantiated.

Yes, like the other two replies. .. you need to make you class public, change the code to
public class Operation
{
......
}
last part bit confusing.. " i want to call it into main - you mean you need to use this class in main .. as this class has only one method and that also public static ( also you are having this class in same project / namespace.
you can call class.methodname i.e. operation.addition(5,6,7) and pass the values.
what do you mean " show all off the value inside that class". - can you clarify this part please..

Two things, you need to take care.
First, make your class public (then only you would be able to access the class).
Second, as this is static method, you can directly access it using the class name as
Classname.methodname(parameters).

In your case, it would be

Operation.addition(2,3,4,5);

You cannot access the objects and methods of a private class. If you are not giving any access specifier, it seems that class is internal, Make it public if you accessing from another assembly and then call it in your main method
public static void Main(string[] args)
{ classname.MethodName(); }
