Before I start ranting, let me just acknowledge that case-sensitivity confers one (and only one) advantage – it makes it easier to name private and public properties: Both VB and C# contain a way of testing mutually exclusive possibilities, the Select Case and Switch clauses respectively. A Visual Basic Select Case clause, returning a description of how old someone is.NET into C#, Andy ' Wise Owl' Brown decided to write a tongue-in-cheek rant whilst he could still remember the pain-points. The age range for a young person is a tad generous, reflecting the age of the author of this article.You can’t do this using Switch in C#, as – astonishingly – it can’t handle relational operators.
