Course Contents

Why C#?
Genesis, features and architecture. Key similarities and differences from other OO languages. Environmental issues - .NET, Windows, etc.
Language fundamentals
Basic syntax and constructs. The C# type system - value and reference types and type conversion. Writing, building and running your first C# program.
Classes, Objects and Namespaces
Classes in C#. Structs Vs. Classes. Creating instances. Member variables and functions. Client access to members. Namespaces and namespace nesting. Static Vs. instance members. Constants and Readonly fields.
Properties
Why Properties? Creating properties - read-only, write-only and read-write.
Inheritance
Inheritance in C#. The base class Object. The String class. Common Object features - Equals() and ToString(). Using inheritance to build flexible canonical designs. Abstract classes and Sealed classes.
Polymorphism
Polymorphism in C# - differences from C++ and Java. virtual, new and override. Practical applications of polymorphism. Versioning.
Interfaces
Multiple inheritance without the pain. Using interfaces to simulate multiple behavior. Extending interfaces.
Operator Overloading
Need for operator overloading. Practical examples of operator overloading. When not to overload an operator. Which operators cannot be overloaded.
Arrays, indexers and collections
Arrays in C#. Multi-dimensional and variable dimension arrays. Why indexers? Creating an indexer. The foreach statement. C# collection interfaces - IList, IComparer, IDictionary, etc. The C# collection classes - ArrayList, Queue and Hashtable.
