How to declare a function with dynamic arguments in c#

Question

Is there a way in c# to declare a function that can take a dynamic number of same type arguments without overloading the function like:

in foo(...)

foo(1) foo(1, 2) foo(1, 2, 3...)

Answer 1

You need to read about params.

You can specify a method's signature such as:

public void Foo(params int[] list)
{
}

Where list is going to be an array of integers.

Answer 2

Use params keyword:

int foo(params int[] arguments)
{
....
}

Answer 3

Using the ParamArrayAttribute you can get the desired effect.

Public void Foo(params int[] list){}

Examples of calling the method:

Foo(1); Foo(1,2); Foo(1,2,3);
