C# Array Class
In C#, Array class deals with all array related operations. It provides methods for various purposes such as for sorting, searching, minimum, maximum, and many more. This class works as a base class for all types of arrays in .Net programming.

C# Array class Methods
C# Array class Example:
[SerializableAttribute] [ComVisibleAttribute(true)] public abstract class Array : ICloneable, IList, ICollection, IEnumerable, IStructuralComparable, IStructuralEquatableC# Array class Properties
| Property | Description |
| IsFixedSize | It is used to get a value indicating whether the Array has a fixed size or not. |
| IsReadOnly | It is used to check that the Array is read-only or not. |
| IsSynchronized | It is used to check that access to the Array is synchronized or not. |
| Length | It is used to get the total number of elements in all the dimensions of the Array. |
| LongLength | It is used to get a 64-bit integer that represents the total number of elements in all the dimensions of the Array. |
| Rank | It is used to get the number of dimensions of the array. |
| SyncRoot | It is used to get an object that can be used to synchronize access to the Array. |
| Method | Description |
| AsReadOnly<T>(T[]) | It returns a read-only wrapper for the specified array. |
| BinarySearch(Array,Int32,Int32,Object) | It is used to search a range of elements in a one-dimensional sorted array for a value. |
| BinarySearch(Array,Object) | It is used to search an entire one-dimensional sorted array for a specific element. |
| Clear(Array,Int32,Int32) | It is used to set a range of elements in an array to the default value. |
| Clone() | It is used to create a shallow copy of the Array. |
| Copy(Array,Array,Int32) | It is used to copy elements of an array into another array by specifying starting index. |
| CopyTo(Array,Int32) | It copies all the elements of the current one-dimensional array to the specified one-dimensional array starting at the specified destination array index |
| CreateInstance(Type,Int32) | It is used to create a one-dimensional Array of the specified Type and length. |
| Empty<T>() | It is used to return an empty array. |
| Finalize() | It is used to free resources and perform cleanup operations. |
| Find<T>(T[],Predicate<T>) | It is used to search for an element that matches the conditions defined by the specified predicate. |
| IndexOf(Array,Object) | It is used to search for the specified object and returns the index of its first occurrence in a one-dimensional array. |
| Initialize() | It is used to initialize every element of the value-type Array by calling the default constructor of the value type. |
| Reverse(Array) | It is used to reverse the sequence of the elements in the entire one-dimensional Array. |
| Sort(Array) | It is used to sort the elements in an entire one-dimensional Array. |
| ToString() | It is used to return a string that represents the current object. |
C# Array class Example:
using System;
namespace CSharpProgram
{
public class Program
{
public static void Main(string[] args)
{
// Creating an array
int[] arr = new int[6] { 5, 8, 9, 25, 0, 7 };
// Creating an empty array
int[] arr2 = new int[6];
// Displaying length of array
Console.WriteLine("length of first array: "+arr.Length);
// Sorting array
Array.Sort(arr);
Console.Write("First array elements: ");
// Displaying sorted array
PrintArray(arr);
// Finding index of an array element
Console.WriteLine("\nIndex position of 25 is "+Array.IndexOf(arr,25));
// Coping first array to empty array
Array.Copy(arr, arr2, arr.Length);
Console.Write("Second array elements: ");
// Displaying second array
PrintArray(arr2);
Array.Reverse(arr);
Console.Write("\nFirst Array elements in reverse order: ");
PrintArray(arr);
}
// User defined method for iterating array elements
static void PrintArray(int[] arr)
{
foreach (Object elem in arr)
{
Console.Write(elem+" ");
}
}
}
}
Output:
length of first array: 6 First array elements: 0 5 7 8 9 25 Index position of 25 is 5 Second array elements: 0 5 7 8 9 25 First Array elements in reverse order: 25 9 8 7 5 0
