C# Array LastIndexOf(T[], T)

Description

Array LastIndexOf(T[], T)searches for the specified object and returns the index of the last occurrence within the entire Array.

Syntax

Array.LastIndexOf(T[], T) has the following syntax.

public static int LastIndexOf<T>(
  T[] array,
  T value
)

Parameters

Array.LastIndexOf(T[], T) has the following parameters.

• T - The type of the elements of the array.
• array - The one-dimensional, zero-based Array to search.
• value - The object to locate in array.

Returns

Array.LastIndexOf(T[], T) method returns The zero-based index of the last occurrence of value within the entire array, if found; otherwise, -1.

Example

The following code example demonstrates all three generic overloads of the LastIndexOf method.

/*w  w w  .j  a  va  2 s  .  c  om*/
using System;

public class Example
{
    public static void Main()
    {
        string[] myValues = { "2001",
            "1999",
            "2000",
            "1234",
            "2002",
            "2001",
            "3211" };


        Console.WriteLine(Array.LastIndexOf(myValues, "2001"));

        Console.WriteLine(Array.LastIndexOf(myValues, "2001", 3));

        Console.WriteLine(Array.LastIndexOf(myValues, "2001", 4, 4));
    }
}

The code above generates the following result.
