C# Array IndexOf(T[], T, Int32)
Description
Array IndexOf(T[], T, Int32)
searches for the
specified object and returns the index of the first occurrence within the
range of elements in the Array that extends from the specified index to the
last element.
Syntax
Array.IndexOf(T[], T, Int32)
has the following syntax.
public static int IndexOf<T>(
T[] array,/* ww w. j av a 2 s .c o m*/
T value,
int startIndex
)
Parameters
Array.IndexOf(T[], T, Int32)
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.startIndex
- The zero-based starting index of the search. 0 (zero) is valid in an empty array.
Returns
Array.IndexOf(T[], T, Int32)
method returns The zero-based index of the first occurrence of value within the range of
elements in array that extends from startIndex to the last element, if found;
otherwise, -1.
Example
The following code example demonstrates all three generic overloads of the IndexOf method.
/*from w w w. j av a2s . c o m*/
using System;
public class Example
{
public static void Main()
{
string[] myValues = { "2001",
"1999",
"2000",
"1234",
"2002",
"2001",
"4567" };
Console.WriteLine(Array.IndexOf(myValues, "2001"));
Console.WriteLine(Array.IndexOf(myValues, "2001", 3));
Console.WriteLine(Array.IndexOf(myValues, "2001", 2, 2));
}
}
The code above generates the following result.
