Is there a C# alternative to Java's vararg parameters?

Yes, C# has a similar feature to Java's varargs called parameter arrays. A parameter array allows a method to accept a variable number of arguments of a specified type, similar to a varargs parameter in Java.

Here's an example of how to use a parameter array in C#:

public void MyMethod(params int[] numbers) { foreach (int number in numbers) { Console.WriteLine(number); } }

In this example, the MyMethod method accepts a parameter array of int values. The params keyword before the parameter type indicates that the parameter is a parameter array, which allows the method to accept any number of int arguments.

You can call the method with any number of int arguments, like this:

MyMethod(1, 2, 3); MyMethod(4); MyMethod();

In this example, the MyMethod method is called three times with different numbers of arguments.

By using a parameter array in C#, you can create methods that accept a variable number of arguments of a specified type, similar to varargs parameters in Java.
