Moq Partial Mocks

Moq is commonly used to create mock objects based upon interfaces. However, it can also be used to mock classes. This includes the possibility of creating partial mocks, where some members are intercepted with expectations whilst others run as normal.

ASCII Table Reference Sheet

The American Standard Code for Information Interchange (ASCII) codes define numeric values for 128 characters, including control characters, letters, numbers and symbols. The code also forms the basis for many other character coding systems.

The System.Type Class

The second part of the Reflection tutorial looks at the System.Type class. This class can be used to represent a type declaration, such as that of a class or structure, and obtain information about that type and its members.

Building Help Files with Sandcastle

XML documentation comments allow useful descriptive information to be attached to types and their members. This information is displayed within Visual Studio whilst coding but sometimes it is more useful to produce documentation as help files.

A SQL Server Leap Year Test Function

Transact-SQL does not provide a standard function that allows developers to determine if a year is a leap year. This article describes two functions. One to calculate the number of days in a year and one that utilises the result to identify leap years.

.NET Reflection

This is the first in a series of articles that describes the use of reflection. Reflection allows assemblies to be examined programatically to obtain information about the classes, structures and members that are defined within.

Visual Studio Call Stack Window

The call stack records each member call, allowing the calling code to be resumed when a member exits. The Call Stack window is a debugging tool in Visual Studio that allows the call stack to be examined whilst a program is paused in debug mode.

Implementing IComparer

The generic IComparer interface was introduced with the .NET framework version 2.0. It is used to compare two values to determine which is the larger. The interface is used in many standard .NET methods, particularly those that sort information.

A Generic Equality Comparer for LINQ

LINQ operators generally use lambda expressions to control their processing and output. Some operators use IEqualityComparer implementations to compare values. This article describes a generic comparer, driven by delegates, designed for use in queries.

Implementing IEqualityComparer

IEqualityComparer is a generic interface defined in the .NET framework version 2.0 and used in many standard classes, including several LINQ operators. The interface can be implemented to allow customised comparison of values and objects.
