In a job interview I had once, I was asked, “How do you store a Boolean in a database?” My first reaction was to say, True, False, 0, 1, Y or N. However, this question has some depth to it. I do not know why, if you do let me know, but there are no […]

I am finding that as you learn to use and implement more sophisticated programming techniques the easier it becomes to created what many would call “complex algorithms”. I believe this, just think about what alternative you have to a Dictionary. I mean other than the similar methods found in the System.Collections or Systems.Collections.Generic classes. Configuration […]

One of, if not the most important concepts in software programming is that of Conditional Methods. Conditional methods provide a program with the ability to make decisions based on user input, user selections or data values. The code below is a simple example of a conditional method: [sourcecode language=”csharp” padlinenumbers=”true” autolinks=”false” gutter=”false” toolbar=”false”] public static […]

Delegates in C# are similar to function pointers in C++ and allow methods to be passed as parameters. In this example we will create a delegate called CalculateCharge and a Withdrawal class: [sourcecode language=”csharp”] delegate decimal CalculateCharge(decimal withdrawal); class Withdrawal { public string AccountOwnerName; public decimal withdrawal; public decimal charge; public CalculateCharge calculation; } [/sourcecode] […]

When we think about the word Generic outside of the programming world it simply means that the object is not tied to any specific kind. An example is a bank account. We may not know which bank it is associated too, if it is a checking or savings account, however we do know that we […]
