What are the uses of Lambda in C#?

Lambda expressions in C# are used for the following purposes:

1. Anonymous functions: Lambda expressions can be used as anonymous functions, without the need to define a function name, and can be used directly where needed.
2. LINQ queries and Lambda expressions are often used together to conveniently filter, sort, and group collections.
3. Delegate: Lambda expressions can be used as parameters for delegates, allowing the implementation logic of the delegate to be defined concisely.
4. Event Handling: Lambda expressions can be used as event handlers to execute specific logic when an event occurs.
5. Asynchronous programming: Lambda expressions can be used as parameters for asynchronous methods, simplifying the code for asynchronous programming.
6. Expression tree: Lambda expressions can be used to create expression trees, which are used for dynamically generating, compiling, and executing code.

In general, Lambda expressions are widely used in C# for functional programming, LINQ queries, delegates, event handling, and other scenarios, helping to simplify code and improve readability and maintainability.
