Differences between C# and VB.Net Syntax

Workflows use VB.Net syntax for expressions.

WorkflowEditor 2.x will support C# syntax for expressions.

	VB.Net	C#
Case-sensitive	no	yes
Null reference	VB `Nothing`	C# `null`
Equals operator	=	==
Equals Not operator	<>	!=
Comparison to null	VB `a is Nothing`	C# `a == null`
Character literal	"a"C	'a'
String escaping	Backslash: "\" Quotes: double quote	Backslash: "\\" or @"\" Quotes: "\"" or @"""" (double quote)
Access indexed elements	Round brackets ( )	Square brackets [ ]
Generic types	VB `New List(Of String) New Dictionary(Of String, Object)`	C# `new List<string>() new Dictionary<string, object>()`
Object initializers	VB `New Entry With { .Title = "Test" }` VB `New List(Of String) From { "abc", "def" }` For a typed array Int32[] VB `{ 3,1,4 }`	C# `new Entry { Title = "Test" }` C# `new List<string> { "abc", "def" }` For a typed array Int32[] C# `{ 3,1,4 }`
Short-circuiting logical operators	VB `a AndAlso b a OrElse b` And/Or are always evaluating ALL parts of it!	C# `a && b a \|\| b`
Non-short circuiting logical operators	VB `a And b a Or b` Example: VB `Not (entry Is Nothing) And entry.Title = "Test"` Will throw exception when entry is Nothing!	n/a
Anonymous function	VB `Function(a,b) a+b`	C# `(a,b) => a + b`
LINQ	VB `a.Select(Function(n) n+1).ToArray()`	C# `a.Select(n => n+1).ToArray()`
Data type names	Integer	int
