배열이 C#에서 읽기 전용인지 확인하십시오.

배열이 읽기 전용인지 확인하려면 아래 코드를 시도하십시오 -

예시

using System;
public class Demo {
   public static void Main(){
      string[] products = new string[] { };
      Console.WriteLine("One or more planets begin with 'E'? = {0}",
         Array.Exists(products, ele => ele.StartsWith("E")));
      Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize);
      Console.WriteLine("Is the array read only? = " + products.IsReadOnly);
   }
}

출력

이것은 다음 코드를 생성합니다 -

One or more planets begin with 'E'? = False
Is the array having fixed size? = True Is the array read only? = False

      string[] products = { "Mobiles", "Laptop", "Watches", "Books" };
      Console.WriteLine("Products list...");
      foreach(string s in products){
         Console.WriteLine(s);
      }
      Console.WriteLine("\nOne or more products begin with the letter 'C'? = {0}",
         Array.Exists(products, ele => ele.StartsWith("C")));
      Console.WriteLine("One or more planets begin with 'D'? = {0}",
         Array.Exists(products, ele => ele.StartsWith("D")));
      Console.WriteLine("One or more products begin with the letter 'T'? = {0}",
         Array.Exists(products, ele => ele.StartsWith("T")));
      Console.WriteLine("One or more planets begin with 'E'? = {0}",
         Array.Exists(products, ele => ele.StartsWith("E")));
      Console.WriteLine("Is the array read only? = " + products.IsReadOnly);
   }
}

출력

이것은 다음 코드를 생성합니다 -

Products list...
Mobiles
Laptop
Watches
Books
One or more products begin with the letter 'C'? = False
One or more planets begin with 'D'? = False
One or more products begin with the letter 'T'? = False
One or more planets begin with 'E'? = False
Is the array read only? = False
