What are the properties of array class in C#?
The Array class is the base class for all the arrays in C#. It is defined in the System namespace. The following are the properties of array class −
Here are the 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. |
Let us see an example to find the number of dimensions of an array, using the Rank property.
arr.Rank
Here, arr is our array −
int[,] arr = new int[3,4];
If you want to get the rows and columns it has, then uses the GetLength property −
arr.GetLength(0); arr.GetLength(1);
The following is the complete code −
Example
using System;
class Program {
static void Main() {
int[,] arr = new int[3,4];
Console.WriteLine(arr.GetLength(0));
Console.WriteLine(arr.GetLength(1));
// Length
Console.WriteLine(arr.Length);
Console.WriteLine("Upper Bound: {0}",arr.GetUpperBound(0).ToString());
Console.WriteLine("Lower Bound: {0}",arr.GetLowerBound(0).ToString());
Console.WriteLine("Dimensions of Array : " + arr.Rank);
}
}Output
3 4 12 Upper Bound: 2 Lower Bound: 0 Dimensions of Array : 2
