Welcome! Today, we'll delve into Data Projection Techniques in C#! Data projection is akin to using a special light to make diamonds shine brighter amidst other gems, aiding their identification.

This lesson will illuminate the concept of data projection, its implementation using C#’s LINQ Select method, and how to integrate it with filtering. Let's forge ahead!

Data projection involves applying a function to a data stream's elements, resulting in a reshaped view. A common instance of data projection is selecting specific fields from datasets.

Data projection in C# employs the Select method from LINQ. You can define a reusable function using Func<int, int> to calculate each number's square, or directly embed the logic within Select for a single use. Here's an illustration using Func:

Use Func for reusability in other code parts, or embed the logic directly inside if it’s a one-time operation.
