Is it valid to use Multiple main methods in C sharp?

[Owen Fernandes]

Hi friends,

I am learning C sharp programming language from one months. I know that C sharp program must contains main method. But my question is that can we use multiple main methods in single C sharp program?. I didn't try this type of program in C# yet. Please let me know you opinion over this C sharp concept. If you know how to use multiple main method then please explain it with suitable example. I would greatly appreciate you help.

Yes, it is valid to use multiple main methods in the same class of C sharp program. C# includes a feature that enables to define more than one class with the Main method. When you use multiple main methods the compiler will inform you that the main method is already defined in the class. We can have multiple main methods with different arguments. Compiler throws an error if we have a method similar to public static void main(String args[]).

Hi friend,

The following C sharp code will depict you about how to implement multiple Main methods in C sharp:

using System;

class CsA1

{
     public static void Main()
     
   {
        Console.WriteLine("Class CsA1");
     }
}

class CsB1

{
     public static void Main()
     
    {
        Console.WriteLine("Class CsB1");
     }
}

Hi,

C Sharp language includes a feature that enables to define more than one class with the Main method. we can use multiple main methods in a class by overloading and not by the overriding. Since 'Main' is the entry point for program execution, there are now more than one entry points. In fact, there should be only one entry point. This problem can be resolved by specifying which Main is to be used to the compiler at the time of compilation.

In C sharp the implementation of multiple main method is achieved through "overloading". By using "overriding" it is possible only in the case of child- parent combination. See following example:

class ASDF
{
public static void main(String args[]){}

}
class ERT extends ASDF
{

public static void main(String args[]){}

}

The C sharp designers included a mechanism by which you are able to define more than one class with a multiple Main method. In addition to this,attempting to compile an C sharp application consisting of multiple C sharp classes with defined Main methods and not specifying the /main switch will result in a compiler error. You can then use the /main:< className > switch with the C# compiler to specify which class's Main method is to be used.
