Question

What is the difference between string and stringbuilder in c#?

Answer 1

A String is basically immutable but on the other hand a string builder is mutable.

A string uses System namespaces.A stringbuilder uses System .text namespaces

A string finds it difficult to append keyword but on the other hand a string builder can append keyboard.

A STRING is basically slower than string builder as it creates new instances every time but stringbuilder is faster than string as it creates only one instance.
