C# in a Nutshell

Chapter 20. C# Language Reference

The following table describes the syntax of various C# language elements. The left column shows the syntax for each element, and the right column includes one or more examples.

Arrays
type [*] + array-name = [ new type [ dimension+ ][*]*; | { value1, value2, ... }; ]	byte[] arr1 = new byte[10]; int[] arr2 = {0, 1, 2}; ([*] is the set: [] [,] [,,] etc.)
Attributes
[[target:]? attribute-name ( positional-param+ | [named-param = expr]+ | positional-param+, [named-param = expr]+)?]	[assembly:CLSCompliant(false)] [WebMethod(true, Description="My web method")]
Break statement
break;	break;
Checked/unchecked
checked (expr) unchecked (expr)	// throws exception short x = 32767; int i = checked((short) ++x ); // silently overflows to -32768 short y = 32767; int j = unchecked((short) ++y );
checked [statement | statement-block] unchecked [statement | statement-block]	// throws exception public short foo() { short y = 32767; checked { return ++y; } } // silently overflows public short bar() { short y = 32767; unchecked { return ++y; } }
Class declaration
attributes? unsafe? access-modifier? new? [ abstract | sealed ]? class class-name [: base-class | : interface+ | : base-class, interface+ ]? { class-members }	public class MyClass : Base, IFoo { // ... }
Constant declaration
const type [variable = constant-expr]+;	const int xyzzy = 42;
Constant fields
attributes? access-modifier? new? const type [constant-name = constant-expr]+;	internal ...
