使用 LINQ 检查课程长度是否超过 2 个字符的 C# 程序

给定一个包含不同课程列表的数组，如“DSA”、“OS”、“JavaScript”等，现在我们的任务是检查给定数组中存在的所有课程的长度是否超过 2 个字符在 LINQ 的帮助下。因此，为了完成我们的任务，我们使用 LINQ 的 All() 方法。如果给定序列中存在的所有元素都满足指定条件，则此方法返回 true。否则，它将返回 false。

句法：

array_name.All(iterator => iterator.Length > 2)

其中array_name 是输入数组，Length 是用于检查每门课程长度的函数。

例子：

Input  : { "cse", "it", "ft", "bio-tech", "chemical" }
Output : False

Input  : { "cse", "ece", "bio-tech", "chemical" }
Output : True

C#

// C# program to find the check the length of
// courses is more than 2 characters Using LINQ
using System;
using System.Linq;
  
class GFG{
  
static void Main(string[] args)
{
      
    // Create 5 courses
    string[] course1 = { "cse", "ece", "bio-tech", "chemical", "civil" };
    string[] course2 = { "DSA", "JS", "Kotlin", "C", "React" };
      
    // Checking the length of all courses 
    // is greater than 2 or not
    bool result1 = course1.All(display => display.Length > 2);
    bool result2 = course2.All(display => display.Length > 2);
      
    Console.WriteLine("Is the length of the courses " +
                      "is greater than 2 in course1?: " + result1);
                        
    Console.WriteLine("Is the length of the courses " +
                      "is greater than 2 in course2?: " + result2);
}
}

输出：

Is the length of the courses is greater than 2 in course1?: True
Is the length of the courses is greater than 2 in course2?: False
