Filtering Collections with LINQ
LINQ (Language Integrated Query) provides a powerful, declarative way to manipulate collections. The intermediate level involves chaining multiple operators to transform data efficiently.

Open snippet →Using async/await allows the application to remain responsive during I/O-bound operations by yielding control back to the caller while waiting for the task to complete.
Open snippet →Records are reference types that provide built-in functionality for encapsulating data. They use value-based equality and support non-destructive mutation via the 'with' expression.
Open snippet →Exception filters allow you to catch an exception only when a specific condition is met. This is cleaner than catching and re-throwing, as it doesn't unwind the stack unnecessarily.
Open snippet →Switch expressions provide a more concise syntax for pattern matching. They allow testing object properties directly and returning a value based on the first match.
Open snippet →The IDisposable interface is used to provide a mechanism for releasing unmanaged resources, such as file handles or database connections, which the Garbage Collector cannot handle automatically.
Open snippet →Extension methods allow you to 'add' methods to existing types without creating a new derived type or modifying the original type. They are defined as static methods in a static class.
Open snippet →Indexers allow instances of a class or struct to be indexed just like arrays. This is useful for classes that represent a collection of data or provide access to internal buffers.
Open snippet →Generic constraints allow you to restrict the types that can be used as arguments for a type parameter. By using 'where T : class, new()', we ensure that T is a reference type and has a public para…
Open snippet →The 'yield return' statement indicates that the method is an iterator. It provides a value to the enumerator without generating the entire collection in memory at once, enabling efficient processin…
