LINQ for Visual C# 2008

1.11. Summary

This long chapter covered the two main parts of LINQ to Objects.

First you examined the new C# 3.0 features to support LINQ. You saw how extension methods extend existing .NET types with new methods. You saw how lambda expressions improve code readability and help us write anonymous methods. You also saw other new features, such as anonymous types and expression trees.

Then you examined all the standard query operators and saw them in code examples to understand their functionality.

The next chapter covers LINQ to SQL, which is dedicated to querying information from relational databases such as Microsoft SQL Server. The query expression syntax you learned in this chapter is also used to query databases.
