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. Signature of Array class:
[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
