Objects

Hi, I have a question about objects in C#. To create an object to access fields, methods and properties of a class I need to use the 'new' keyword. When I use a class as a type and a parameter in a method, I just declare the type and name of the object and then use it in the method. Why don't I need to use the 'new' keyword there?

When you declare a class as a parameter you are telling C# "This method requires that an object of this class is passed in to it". And when you reference that parameter within your code you are referencing the object that was passed in when the method was called.

That means that you aren't actually creating an object, you are just specifying that an object is required. And then referencing that object in your code. When you actually call that method you will have to create an object to pass into it, and at that point the new keyword will be used.

So new is always used when creating the object from scratch, but not when an existing object is being passed around.
