C# - Check length of courses using LINQ

Learn, how to check the length of courses is more than 2 characters using Linq in C#? By Nidhi Last updated : April 01, 2023

Here, we will create an array of strings that contains courses. Then we check the length of all courses is more than two characters or not using Linq All() method.

C# program to check the length of courses is more than 2 characters using LINQ

The source code to check the length of courses is more than 2 characters using Linq, which is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to check the length of courses is 
//more than 2 characters using Linq

using System;
using System.Linq;

class LinqDemo
{
    static void Main(string[] args)
    {
        string [] courses = { "BCA", "MCA", "MBA", "CCNA"};

        bool isgreater = false;
        
        isgreater = courses.All(c=>c.Length>2);
        
        Console.WriteLine("The length of all courses is more than 2 characters? --> " + isgreater);
    }
}

Output

The length of all courses is more than 2 characters? --> True
Press any key to continue . . .

Explanation

In the above program, we created a LinqDemo that contains the Main() method. In the Main() method we created an array of strings that contain academic courses.

isgreater = courses.All(c=>c.Length>2);

The above code will return a boolean value, here we check the length of all courses which are more than 2 characters or not. If the length of all courses is more than 2 characters then All() method will return true otherwise it will return false.
