Question

In C# which namespace contains LINQ?

In C# the output of the following code is ______

static void Main(string[] args)

{

int[] nums = { 1, 0, 6, -2, -4, 3};

var posNums = from n in nums where n % 2 == 0 select n;

foreach (int i in posNums)

Console.Write(i + " ");

}

In C# which of following is correct for the blank?

static void Main(string[] args)

{ int[] nums = { 8, -2, -1, 2, 6, -4, 5 };

int count = /*_________________ */ ;

Console.WriteLine("The number of positive numbers is: " + count);

Console.ReadLine(); }

In C# the ________ extension method indicates that only unique values should be included in a LINQ query s results.

What is LINQ (Language Integrated Query)?

System.Text

Answer)

1) In C# the namespace that contains LINQ is System.Linq

So as to support the Linq query language this name space provides the classes and interfaces for the same.

2) The output of the code would be 0 , 6, -2, -4

As the modulus of 2 is the operation that is to be performed hence the mod of 2 giving zero as the result has the above numbers as output.

4) Distinct is the extension method which indicates the unique values which are to be included in LINQ Query.

The extension methods when explicitly import the name space codes using the directives are the only scope.

5) LINQ is a .Net Framework

This helps to add the data querying ability to .NET and not itself is a query language or an API.

Hope this answer helps. :) Happy to help.
