CSharp VAR Misconceptions
September 7th, 2009 | 
Author: 
I find it amazing that .NET 3.5 has been out for over a year and people still don’t understand the “var” keyword.
Just last week I got a comment on one of my videos asking why I used “var” so much. Isn’t that only supposed to be used when you don’t know what the return type is going to be?
Clearly, this person does not understand what “var” does or how it should be used.

Renaming Properties, Methods and Variables
Have you ever written some code and named something one thing only to realize that it should be named something else?
If you haven’t you haven’t been programming for very long. Maybe you started a new job and you spent two weeks writing code using your previous employer’s naming conventions only to find out that this employer expects things to be named slightly differently.
So now you not only have the item named incorrectly, but you’ve referenced it from other files, so it isn’t a simple matter of just giving it a new name. No, the code that is referencing it has to be changed as well. So what are you going to do?

Easily Find Classes, Methods, and Variables
There is a bit of a “trick” that I use routinely in Visual Studio to help me find the definition of Classes, Methods, and Variables in my solution regardless.
This “trick” works in both CSharp and in VB.NET and, if you don’t know it already, will save you a ton of time.

Readonly variables in CSharp? Really?!
I’m sure most of you are familiar with the keyword “const,” which allows you to declare a variable and give it a value and assures that no other code will change the value.
const int v = 23; public void Foo() { // This causes a compile error v = 22; }
But what about the times when you need something that kind of works like a const but needs to be initialized by the constructor? Read the rest of this entry »

24 Game VariablesCards have 2 wheels; each wheel has 3 numbers with 1 number missing. Goal: Try to find a VARIABLE NUMBER (any whole number from 1 to 9) which, when used with the other numbers on the card, can make 24 on both wheels. [Hint: Try the number 2.] More difficult than Single Digits or Double Digits.
