 Explain async, await and lock keyword in C#

1. async/await:

async/await is a feature in C# that allows you to write asynchronous code in a synchronous style. The async keyword is used to mark a method as asynchronous, and the await keyword is used to wait for the completion of an asynchronous operation. This allows you to write code that looks like it is synchronous but is actually asynchronous and does not block the main thread.

2. lock:

The lock keyword is used in C# to provide synchronization between multiple threads that access a shared resource. When a thread acquires a lock on a resource, it prevents other threads from accessing that resource until the lock is released. This ensures that only one thread can access the shared resource at a time, preventing race conditions and other synchronization issues.

The basic syntax for using lock in C# is as follows:

lock (lockObject)

{

    // Code that accesses a shared resource

}

Here, lockObject is an object that is used to synchronize access to the shared resource.

It is important to note that the use of lock can introduce performance issues, as it can cause threads to wait for access to a shared resource, slowing down the overall performance of the application.

In summary, async/await is used for asynchronous programming, while lock is used for synchronization between multiple threads that access a shared resource.
