What is the difference between String and StringBuilder in C#?

What is the difference between String and StringBuilder in C#?

In C#, a String is immutable, meaning once it's created, it cannot be changed. StringBuilder, on the other hand, is mutable and allows for dynamic string manipulation.

Can you give me an example of when to use StringBuilder?

Sure! Use StringBuilder when you need to concatenate strings in a loop or perform multiple modifications, as it is more efficient in those cases.

What are the performance implications of using String vs StringBuilder?

Using String in scenarios with many modifications can lead to performance issues due to the creation of multiple string instances. StringBuilder is more efficient as it modifies the same instance.

Are there any limitations to using StringBuilder?

Yes, while StringBuilder is great for performance, it is less convenient for simple string operations compared to String, and it doesn't provide some of the built-in methods that String does.
