How to get Sub Array in C# ?

Answer

To get a sub-array in C#, you can use the `ArraySegment` struct or array slicing.

✐ Examples

1 Sub-array of Integer Array

In this example,

We create an integer array named numbers with some values.
We then use array slicing to get a sub-array from index 2 to index 4 (exclusive).
Finally, we print the sub-array.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[] numbers = { 1, 2, 3, 4, 5 };
        int[] subArray = new ArraySegment<int>(numbers, 2, 2).ToArray();
        Console.WriteLine("Sub-array: " + string.Join(", ", subArray));
    }
}

Output

Sub-array: 3, 4

2 Sub-array of String Array

In this example,

We create a string array named colors with some values.
We then use array slicing to get a sub-array from index 1 to index 3 (exclusive).
Finally, we print the sub-array.

C# Program

using System;
class Program
{
    static void Main()
    {
        string[] colors = { "red", "green", "blue", "yellow", "orange" };
        string[] subArray = new ArraySegment<string>(colors, 1, 2).ToArray();
        Console.WriteLine("Sub-array: " + string.Join(", ", subArray));
    }
}

Output

Sub-array: green, blue
