Chapter 14, Problem 1MC

Program Description Answer

If a LINQ query’s source of data is a List<int>, then the return type will be a collection of “IEnumerable<int>”.

Hence, the correct answer is option “C”.

Explanation of Solution

Example query:

var results =  from item in values

  where item > 10

  select item;

• The above query is used to select the records whose value is greater than 10 in the table item.
• The query returns the result and stores it in a variable “results”, the datatype of the “results” variable is “IEnumerable<int>” collection.
  • The query’s data source is an array of “int” datatype, hence the query returns “IEnumerable<int>” collection.
