C# is hybrid of C and C++. The Microsoft Programming Language develops to compete with Sun's Java language. C# is an object-oriented programming language used with XML-based Web services on the .NET platform and design to improve productivity in the development of Web applications. C# syntax simplifies complexities in C++ and provides powerful features such as nullable value types, enumerations, delegates, lambda expressions and direct memory access, which not found in Java. C# supports generic methods and types, which provide increased type safe and performance, and iterators enables the implementers of the ‘collection classes’ to define custom iteration behaviors that easy to use by client code. Language-Integrated Query (LINQ) expressions make strongly-typed query a first-class language construct.
