Language Integrated Query (LINQ) is a Microsoft .NET Framework component that adds native data querying capabilities to .NET languages.

If you want to master Language Integrated Query (LINQ), you first need to understand the expressions it is based on. This blog post demonstrates how to dynamically build a LINQ expression tree with multiple nested conditions, use the compiled query to filter an in-memory list, then reuse the expression query a relational database.
The Rx library utilizes the power of LINQ to make difficult asynchronous problems simple.
LINQ (Language INtegrated Query) is a set of features in C# for concise and declarative code. I use it pretty much wherever I can, but sometimes I wonder and people ask: is this a performance trap? It would be painful to have to replace many usages of LINQ with other constructs in addition to time spent finding that to be an actual bottleneck. Let’s do a basic benchmark to see what using LINQ might cost us compared to more traditional constructs such as for and foreach loops, and see if this worry is valid.
I have a list of <code>IPInfo</code> objects already filtered in some way. My problem is to separate records based on last <code>List<String></code> property:
I'm trying to find equal sub-string in big list about 50 000 strings, this way fine:
I have classes for building many to many relationships.
I've inherited some code from a former employee that queries a mongo DB using compiled Linq expressions and the <a href="https://github.com/RobThree/MongoRepository" target="_blank">MongoRepository library</a> (which sits on top of the MongoDB C# driver).
I have a simple search function that allows me to search for certain words from different tables. This is annoying as I feel there is a simple fix i'm not seeing here. Can someone assist? Thank you in advance.
There is a table 'Result' with following data:
