Arrays in C# are fixed in size and do not have built-in methods for dynamic operations (like Add or Remove). However, you can perform CRUD operations by working with array elements.
1. Create Operation
You can initialize arrays with specific values or create an empty array and populate it later.
Example
// Creating an array with predefined values int[] numbers = { 10, 20, 30 }; // Creating an empty array and assigning values later int[] grades = new int[3]; grades[0] = 85; grades[1] = 90; grades[2] = 78; 2. Read Operation
Access specific elements or iterate through the array.
Example
int[] numbers = { 10, 20, 30 }; // Accessing elements by index Console.WriteLine(numbers[0]); // Output: 10 // Iterating through the array foreach (var num in numbers) { Console.WriteLine(num); } 3. Update Operation
Modify existing elements by accessing them via their index.
int[] numbers = { 10, 20, 30 }; // Updating the value at index 1 numbers[1] = 25; foreach (var num in numbers) { Console.WriteLine(num); } // Output: 10, 25, 30
