What is the difference between FirstOrDefault() and SingleOrDefault() extension method in LINQ ?..

Answer / Akhil Tripathi

FirstOrDefault() returns null if no elements are found, whereas SingleOrDefault() throws an exception if more than one element is found. In other words, FirstOrDefault() does not guarantee that only one result will be returned, while SingleOrDefault() ensures it.
