Array.Rank Property is used to get the rank of the Array. Rank is the number of dimensions of an array. For example, 1-D array returns 1, a 2-D array returns 2, and so on.
Syntax:
public int Rank { get; }
Property Value: It returns the rank (number of dimensions) of the Array of type System.Int32.
Below programs illustrate the use of above-discussed property:
Example 1:
// C# program to illustrate the // Array.Rank Property using System;
namespace geeksforgeeks {
class GFG {
// Main Method
public static void Main()
{
// declares a 1D Array of string.
string [] weekDays;
// allocating memory for days.
weekDays = new string [] { "Sun" , "Mon" , "Tue" , "Wed" ,
"Thu" , "Fri" , "Sat" };
// using Rank Property
Console.WriteLine( "Dimension of weekDays array: " + weekDays.Rank);
}
} } |
Output:
Dimension of weekDays array: 1
Example 2:
// C# program to illustrate the // Array.Rank Property using System;
namespace geeksforgeeks {
class GFG {
// Main Method
public static void Main()
{
// declaring an 2-D array
int [, ] arr2d = new int [4, 2];
// declaring an 3-D array
int [,, ] arr3d = new int [4, 2, 3];
// declaring an jagged array
int [][] jdarr = new int [2][];
// using Rank Property
Console.WriteLine( "Dimension of arr2d array: " + arr2d.Rank);
Console.WriteLine( "Dimension of arr3d array: " + arr3d.Rank);
// for the jagged array it
// will always return 1
Console.WriteLine( "Dimension of jdarr array: " + jdarr.Rank);
}
} } |
Output:
Dimension of arr2d array: 2 Dimension of arr3d array: 3 Dimension of jdarr array: 1
Note:
- A jagged array (an array of arrays) is a one-dimensional array so the value of its Rank property is 1.
- Retrieving the value of this property is an O(1) operation.
