C# Order of Operators (C# 6)

In hopes to better understand the order of operators in C# (6 & 7, but most will work for lower versions too), I decided to make a cheat sheet for myself in a table format. The list / section on the MSDN was helpful, but I wanted something a little more pleasing to my eyes… anyway, thought I’d share!

Getting the Client’s IP with C#

I needed a pretty reliable and easy way to get the client’s IP address in one of the applications I’m working on.

SqlCommand.Parameters.Add() vs SqlCommand.CreateParameter()

When doing some quick research on SQL Parameters with SqlCommand, I noticed two methods which seemed to perform the same task, SqlCommand.Parameters.Add() and SqlCommand.CreateParameter(). After looking into each method on MSDN, I noticed that CreateParameter() will simply create the parameter, while Parameters.Add() will create the parameter and add it to the parameter collection. SqlCommand.Parameters.Add() The following example will create a SQL command object, create...
