R1D15 Methods and Exception Handling in C# and Azure Notebooks

I wrapped up the Introduction to C# course today by reviewing methods and exception handling in C#. Like Java C# supports access controls such as private, public, protected, and static.

My certificate is “signed” by Satya Nadella, which motivates me.

C# Methods

You do not need to understand how the code in a method works. You may not even have access to the code, if it is in a class in an assembly for which you do not have the source, such as the .NET Framework class library.

I learned about ref and out, which are a bit strange to me. They allow you to return multiple values from a method call without having the method itself return anything at all. In python if we want to return multiple values we would usually return an array or some other list.

I also learned that you are able to used named parameters in C# methods. This is really cool. If you have a complex method that takes many optional arguments, you can specify the specific ones that you want by name. Or if you want to reduce ambiguity for which parameters are being passed in you can give them a name. I think this makes code a lot more readable.
