1. Introduction

1.1 Purpose

The purpose of this document is to provide coding style standards for the development of source code written in C#. Adhering to a coding style standard is an industry proven best-practice for making team development more efficient andapplication maintenance more cost-effective. While not comprehensive, these guidelines represent the minimum level of standardization expected in the source code of projects written in C#.

1.2 Scope

This document provides guidance on the formatting, commenting, naming, and programming style of C# source code and is applicable to component libraries. web services, web sites, and rich clientapplications.

1.3 Document Conventions

Example code is shown using the Code font and shows syntax as it would be color coded in Visual Studio’s code editor.

1.4 Feedback

Feedback on these guidelines is highly encouraged. Please send any questions or comments to your application architect.

2. C# Golden Rules

The following guidelines are applicable to all aspects C# development:

o Followthe style of existing code. Strive to maintain consistency within the code base of an application. If further guidance is needed, look to these guidelines and the .NET framework for clarification and examples.

o Make code as simple and readable as possible. Assume that someone else will be reading your code.

o Prefer small cohesive classes and methods to large monolithic ones.

o Use aseparate file for each class, struct, interface, enumeration, and delegate with the exception of those nested within another class.

o Write the comments first. When writing a new method, write the comments for each step the method will perform before coding a single statement. These comments will become the headings for each block of code that gets implemented.

o Use liberal, meaningfulcomments within each class, method, and block of code to document the purpose of the code.

o Mark incomplete code with // TODO: comments. When working with many classes at once, it can be very easy to lose a train of thought.

o Never hard code “magic” values into code (strings or numbers). Instead, define constants, static read-only variables, and enumerations or read the values from configurationor resource files.

o Prefer while and foreach over other available looping constructs when applicable. They are logically simpler and easier to code and debug.

o Use the StringBuilder class and it’s Append(), AppendFormat(), and ToString() methods instead of the string concatenation operator (+=) for much more efficient use of memory.

o Be sure Dispose() gets called on IDisposable...
