Getting 3 random records from a table

问题

I've read multiple answers to a similar query, but none seem to hit the spot.

Imagine I have a table that contains 10 rows, how do I retrieve 3 random rows from this table using Entity Framework? Not just 1 random row, but 3 random rows - each being different from the other?

Thanks in advance

回答1:

var threeRandomFoos = foos.OrderBy(x => Guid.NewGuid()).Take(3);

回答2:

Instead, there is a simpler way,

var threeRandomFoos = foos.OrderBy( x=> SqlFunctions.Rand()).Take(3);

Guid.NewGuid will be little slower in performance, why not use Random specified by SqlFunctions itself?
