Compilation A C# program consists of one or more source files (with filename suffix cs) A source file may contain one or more type declarations: classes, interfaces, struct types, enum types, and delegate types Before a C# program can be executed, it must be compiled and loaded The C# compiler, such as Microsoft’s csc or the Mono project’s mcs, checks that the program conforms to the syntax for C# programs,... parameter or field or array element In this book, fragments of the C# grammar are presented using an informal notation, with non-terminal symbols such as class-declaration in italics, terminal symbols such as class in typewriter font, and metavariables such as C for class names and M for method names A complete and detailed grammar for C# can be found in the official language specification (see section... of the name proper The pseudo-keywords add, alias, get, global, partial, remove, set, value, where and yield are reserved only in certain contexts 3 C# Naming Conventions The following naming conventions are often followed, although not enforced by the C# compiler: • If a name is composed of several words, then each word (except possibly the first one) begins with an upper case letter Examples: currentLayout,... other programming languages, in which class or public may be a perfectly legal name for a field or method; it should not be used in ordinary C# programming Note that for non-keywords such as i, the identifier @i is the same as i class School { const int @class = 2004; const bool @public = true; String @delegate = "J Smith "; public static int @double(int i) { return 2 * @i; } } School school = new School();... see examples 1 and 2 The /main compiler option can be used to specify the entry point: the class whose Main method must be executed after loading an executable Team-LRN Compiling, Loading and Executing C# Programs 3 Example 1 Complete Program in File Example1.cs Almost all programs need the using System directive (section 25.1) but we leave it out in later examples using System; public class Sum { static... There are standard conversions between all the simple types except bool A conversion marked I is an implicit conversion (no cast required) and one marked E is an explicit conversion (cast required) More precisely, an implicit conversion marked I cannot lose precision, whereas one marked IL may lose precision; neither can throw an exception An explicit conversion marked ER rounds the source value and so... pattern, which is a combination of one or more of the following predefined custom number formatting codes: 0 # , % E0 e0 E+0 e+0 E-0 e-0 ; ’string’ "string" See example 26 and the Net Framework class library documentation for details 7.2.2 DateTime Formatting The code part of a format specification for an object of type DateTime may be one of the predefined standard DateTime formatting codes: Code Character... specification for an object of type DateTime may also be a custom DateTime formatting pattern, which is a combination of one or more of the many predefined custom DateTime formatting codes See the Net Framework documentation for details Team-LRN Strings 23 Example 25 Some Standard Number Format Patterns and Their Effect Formatting is culture sensitive This table shows the formatting obtained in the en-US culture . class="bi x0 y0 w0 h0" alt="" C# Precisely Team-LRN Team-LRN Peter Sestoft Henrik I.
