Array.LastIndexOf(T[], T) Method in C#
The Array.LastIndexOf() method in C# is used to search for the specified object and returns the index of the last occurrence within the entire Array.
Syntax
Following is the syntax −
public static int LastIndexOf<T> (T[] array, T val);
Above, the parameter arr is the one-dimensional, zero-based Array to search, whereas Val is the object to locate in an array.
Example
Let us now see an example to implement the Array.LastIndexOf() method −
using System;
public class Demo{
public static void Main(){
Console.WriteLine("Array elements...");
string[] arr = { "car", "bike", "truck", "bus"};
for (int i = 0; i < arr.Length; i++){
Console.Write("{0} ", arr[i]);
}
Console.WriteLine();
int lastIndex = Array.LastIndexOf(arr, "bus");
Console.WriteLine("Last Ocurrence of element bus is at index = "+lastIndex);
}
}Output
This will produce the following output −
Array elements... car bike truck bus Last Ocurrence of element bus is at index = 3
