Data Types

100

The two types of variables in C#

What are reference and Value types

200

Reference types are stored in this piece of memory

What is the Heap?

300

M, D and F. Appending these characters to a number casts it to these types, respectively.

Decimal, Double, Float

400

This operator allows you to safely assign a value which might be null, and assign a default value otherwise.

What is the null-coalescing operator? (??)

500

This data type allows for easier manipulation of strings, whose immutable nature otherwise makes them process-intensive to edit

What is StringBuilder?

Syntax

100

The four kinds of loops in C#

What are for, While, do-While, and foreach

200

In order to create a custom exception, you must extend it from this class.

What is Exception? (Hell yeah it was that easy)

300

Like 'out', this keyword allows you to mark a parameter so that changes made to it are passed back out. Unlike with out, the function is not required to make changes.

What is 'ref'?

400

In this situation, you need a 'finally' block, otherwise the code after a try/catch statement won't execute.

What is Try/Catch return a value
OR
What is an exception thrown in the catch bloc

500

Assuming val has been declared appropriately beforehand, this the value of val after this code is run

int a=2,b=3,c=4,d=6;

val =  b-c*a == c%3-d;

What is true?

Collections

100

This is the only non-generic collection in C#

What is an array?

200

This is like an array, but has a flexible length that doesn't need to be declared right away.

What is a list?

300

This is the command used to add elements to a Queue

What is enqueue?

400

These are the four generic collections available in C#

What are list, queue, stack and dictionary?

500

Queues and Stacks are used to access members in a particular order, described by these four-word-compound-phrases

First in First out/Last in First out

Classes

100

This keyword flags a class (and its members) so that they cannot be declared, but derived classes must include any marked members and their implementations

What is abstract

200

This is the default access modifier for a class in C# (shoutouts to Josh)

What is Internal

300

This keyword flags a class so that no classes can be derived from it

What is sealed?

400

Using this keyword after a constructor in a derived class allows 

What is base?

500

Use this convention when declaring a static member

What is s_CamelCase

Miscellaneous

100

It is Epic (and microsoft) convention to start these types with 'I'

What is an interface?

200

These are the only things you should use camelCase for.

Local Variables, Parameters

(With s_ and _ prefix for private/static variables)

300

This is required of any delegate functions in order to support multicasting

What is null return type

400

The issue in this code:

int x = 4;

switch (x) {

    case 1:

    //code

    break;

    case 3:

    //code

    break;

    case default:

    //code

    break;

}

The default case is just called with default: you don't need to use the case keyword

500

How does a public delegate field differ from an event of the same delegate type in a class?

(What is) The public delegate field can be invoked outside of the class directly, events cannot.
