The C# Array Class is the base class for all the arrays in C#. It is defined in the System namespace. The Array class provides various properties.
Methods To Work With C# Array Class
Properties of the Array Class
The following table describes some of the most commonly used properties of the Array class −
| Sr.No. | Property & description |
|---|---|
| 1 | IsFixedSize Gets a value indicating whether the Array has a fixed size. |
| 2 | IsReadOnly Gets a value indicating whether the Array is read-only. |
| 3 | Length Gets a 32-bit integer that represents the total number of elements in all the dimensions of the Array. |
| 4 | LongLength Gets a 64-bit integer that represents the total number of elements in all the dimensions of the Array. |
| 5 | Rank Gets the rank (number of dimensions) of the Array. |
Methods of the Array Class
The following table describes some of the most commonly used methods of the Array class −
| Sr.No. | Methods & Description |
|---|---|
| 1 | ClearSets a range of elements in the Array to zero, to false, or to null, depending on the element type. |
| 2 | Copy(Array, Array, Int32)Copies a range of elements from an Array starting at the first element and pastes them into another Array starting at the first element. The length is specified as a 32-bit integer. |
| 3 | CopyTo(Array, Int32)Copies all the elements of the current one-dimensional Array to the specified one-dimensional Array starting at the specified destination Array index. The index is specified as a 32-bit integer. |
| 4 | GetLengthGets a 32-bit integer that represents the number of elements in the specified dimension of the Array. |
| 5 | GetLongLengthGets a 64-bit integer that represents the number of elements in the specified dimension of the Array. |
| 6 | GetLowerBoundGets the lower bound of the specified dimension in the Array. |
| 7 | GetTypeGets the Type of the current instance. (Inherited from Object.) |
| 8 | GetUpperBoundGets the upper bound of the specified dimension in the Array. |
| 9 | GetValue(Int32)Gets the value at the specified position in the one-dimensional Array. The index is specified as a 32-bit integer. |
| 10 | IndexOf(Array, Object)Searches for the specified object and returns the index of the first occurrence within the entire one-dimensional Array. |
| 11 | Reverse(Array)Reverses the sequence of the elements in the entire one-dimensional Array. |
| 12 | SetValue(Object, Int32)Sets a value to the element at the specified position in the one-dimensional Array. The index is specified as a 32-bit integer. |
| 13 | Sort(Array)Sorts the elements in an entire one-dimensional Array using the IComparable implementation of each element of the Array. |
| 14 | ToStringReturns a string that represents the current object. (Inherited from Object.) |

Example
The following program demonstrates the use of some of the methods of the Array class
using System;
namespace ArrayApplication {
class MyArray {
static void Main(string[] args) {
int[] list = { 34, 72, 13, 44, 25, 30, 10 };
int[] temp = list;
Console.Write("Original Array: ");
foreach (int i in list) {
Console.Write(i + " ");
}
Console.WriteLine();
// reverse the array
Array.Reverse(temp);
Console.Write("Reversed Array: ");
foreach (int i in temp) {
Console.Write(i + " ");
}
Console.WriteLine();
//sort the array
Array.Sort(list);
Console.Write("Sorted Array: ");
foreach (int i in list) {
Console.Write(i + " ");
}
Console.WriteLine();
Console.ReadKey();
}
}
}
When the above code is compiled and executed, it produces the following result −
Original Array: 34 72 13 44 25 30 10 Reversed Array: 10 30 25 44 13 72 34 Sorted Array: 10 13 25 30 34 44 72
