Code Blocks (C# and VB Classic Cross Reference Guide)

By Mike Prestwood

C# versus VB Classic: A side by side comparison between C# and VB Classic.

Language Basics

Language basics is kind of a catch all for absolute beginner stuff. The items (common names) I chose for language basics is a bit random and include items like case sensitivity, commenting, declaring variables, etc.

Code Blocks

[Other Languages]

Languages Focus

The rules for code blocks within a language dictate where you can declare variables, how you "bracket" code, etc.

C#: { }

C# uses braces {} to indicate a code block of more than one line. For one line of code, the braces are optional.

I prefer to put the opening { and the closing } on their own line only because most of the examples I see do this. As opposed to C++, Java, and JavaScript where I put the opening bracket at the end of the first line (which I actually prefer).

Syntax Example:

int DoSomething()

 int a = 1;

 int b = 2;

 return a + b;

VB Classic: End Xxx

VB Classic code blocks are surrounded by statement ending keywords that all use End such as End Sub, End If, and WEnd.

Syntax Example:

Sub x

End Sub

If x Then

End If

While x

WEnd
