Lambdas & LINQ in C#

Stars

LINQ (Language Integrated Query) is a very powerful tool for processing data — including filtering, sorting, and various types of aggregation. Lambda Expressions play a key role in LINQ methods, so we’ll spend some time understanding lambdas. And then we’ll see how to use them in LINQ methods by making sense of the method signatures that we find in the documentation. Once we understand the methods, the entire world of LINQ is open to us.
