What is the difference between Count() and LongCount extension methods in LINQ?

Question Posted / prameela


What is the difference between Count() and LongCount extension methods in LINQ?..

Answer / Deepak Nigam

Both Count() and LongCount are extension methods that return the number of elements in a sequence, but they differ in the type of result. Count() returns an Int32, while LongCount returns a Long (Int64). This makes Count() suitable for sequences that can fit within an integer, and LongCount suitable for larger sequences.
