C# Array Class

In the C# programming language, the array class is in the System namespace, which offers techniques for array creation, searching, sorting, and manipulating arrays. However, it is not part of the System.Collections namespace, it implements interfaces like IList, ICollection, and IEnumerable, which allows it to be treated as a collection.

Syntax of Array Class:

It has the following syntax.

In this syntax,

• arrayName: It represents the name of the array.
• typeof(datatype): It represents the data type of array elements.
• length: It represents the length of the array elements.

C# Array Class Example

Let’s take an example to define the array class in C#.

Output:

The Length of the original array: 6
The Sorted original array elements: 0 5 7 8 9 25 
The Index position of 25 is 5
The Copied array elements: 0 5 7 8 9 25 
The Original array in reverse order: 25 9 8 7 5 0   

Explanation:

In this example, we create an integer array and assign the values to it. The elements are rearranged in a sorted order using the sort() function, and then it prints the sorted elements. After that, it copies the sorted array into a new array and displays the copied values. Finally, it reverses the original array and prints the reversed elements.

Important Points of the Array Class in C#:

There are several important points of the array class in C#. Some of them are as follows:

• The length of an array is determined by how many elements it contains.
• The index of the first element of an array always starts with zero by default.
• An array has a default size of 2GB.
• The arrays with the same type use the same class object.

C# Array Properties

There are several properties of the array class in C#. Some of them are as follows:

C# Array Method

There are several methods of the array class in C#. Some of them are as follows:

Illustration of the Array Length property

Let’s take an illustrate example to determine the size of an array using the Length property in the C# programming language.

Output:

The length of the array is: 5 

Explanation:

In this example, first, we create an integer array and assign the values. After that, we use the Length property to calculate the size of an array. Finally, we use the Console.WriteLine() function to print the output.

Example: Using the rank property to determine the array dimensions

Let’s take an illustrate example to calculate the array dimensions using the rank property.

Output:

The number of dimensions: 1
Elements of the array:
10 20 30 40 50

Explanation:

In this example, first, we create a one-dimensional array in C#, and then use the rank property to calculate the dimensions of the array. After that, we use the for loop to iterate over the elements of the array. Finally, we are using the Console.WriteLine() function to print the output.

Conclusion

In the C# programming language, the array class is in the System namespace, which offers techniques for array creation, searching, sorting, and manipulating arrays. It is the key factor for any programmer to create a software application. It has several properties and methods to perform a particular task.
