Program Explanation

This C# program used to calculate size of file using LINQ. LINQ (Language Integrated Query) is uniform query syntax used to save and retrieve data from different sources. It is integrated thereby eliminating the mismatch between programming languages and databases, as well as providing a single querying interface for different types of data sources.
