linq in c# code example

Example 1: linq in c#

// Data source
string[] names = {"Bill", "Steve", "James", "Mohan" };

// LINQ Query 
var myLinqQuery = from name in names
                where name.Contains('a')
                select name;
    
// Query execution
foreach(var name in myLinqQuery)
    Console.Write(name + " ");

Example 2: linq in c#

class LINQQueryExpressions
{
    static void Main()
    {

        // Specify the data source.
        int[] scores = new int[] { 97, 92, 81, 60 };

        // Define the query expression.
        IEnumerable<int> scoreQuery =
            from score in scores
            where score > 80
            select score;

        // Execute the query.
        foreach (int i in scoreQuery)
        {
            Console.Write(i + " ");
        }
    }
}
// Output: 97 92 81

        // Specify the data source.
        int[] scores = new int[] { 97, 92, 81, 60 };
