This book is a set of well-documented programs in the C # language. The programs demonstrate using basic C# instructions, performing I/O operations, working with arrays, lists, and files. Shows how to define and use objects. It also shows how to use LINQ technology to perform operations with different data sources: arrays, lists, XML documents.
For beginners programmers
