suresh What is the difference between First() and FirstOrDefault() methods in LINQ?
When using LINQ in C#, the key difference between the First() and FirstOrDefault() methods lies in how they handle empty collections. The focus keyword here is "difference between First() and FirstOrDefault() methods in LINQ".
First() will throw an exception if the sequence does not contain any elements, whereas FirstOrDefault() will return the default value for the element type (e.g., null for reference types, 0 for numbers) if the sequence is empty. This makes FirstOrDefault() a safer choice when you are not certain that your sequence will always have elements.
It is important to consider the use case and potential for empty collections when deciding between First() and FirstOrDefault() in LINQ queries to ensure smooth and error-free execution of your code.
