Error: Sequence contains more than one element
That is an
InvalidOperationExceptionthrown by theSinglemethod.This method is supposed to return only one element, and your query is returning more than one, you have to check the criteria you use on your query.
It will also throw an exception if it doesn’t find an element. You can use
SingleOrDefault()method to return null (or default value, i.e. 0 for int) if there are no records.If you are expecting multiple elements but just one the first one, you can use
Firstinstead ofSingleorFirstOrDefault.
