What is the Aggregate function in C# LINQ?

The Aggregate function in C# LINQ is used to apply an accumulator function over a sequence. It can be used to compute a single value from a collection.

Can you give me an example of how to use it?

Sure! Here's a simple example: int sum = numbers.Aggregate((total, next) => total + next); This sums all the numbers in the collection.

What types of operations can I perform with Aggregate?

You can perform various operations like sum, product, concatenation, or even custom operations by defining your own accumulator function.

Are there any performance considerations I should be aware of?

Yes, using Aggregate on large collections can be less efficient than other methods like Sum or ForEach, so consider the size and complexity of your data.
