- Q1. Difference between first() or FirstOrDefault()
- Ans.
first() returns the first element of a sequence, while FirstOrDefault() returns the first element or a default value if the sequence is empty.
first() throws an exception if the sequence is empty, while FirstOrDefault() returns a default value (e.g. null) in that case.
Use first() when you expect the sequence to always have at least one element, and FirstOrDefault() when the sequence might be empty.
Example: var numbers =...
