VB.NET IndexOf()

Description: Illustrates using VB.NET IndexOf() Code Example.

Example Class:

Public Class clsIndexOf
 
    Public Sub Main()
 
 
 
        '****************************************************************************************
        ' Example #1: IndexOf(string[, startIndex][,count])
        ' Returns an integer that represents the position of the first occurrence of the
        ' specified number of characters. If you specify startIndex, that specifies
        ' where to start looking. If you specify count, that specifies how many characters to 
        ' to search past start. If the string is not found, this method returns -1
        '****************************************************************************************
 
        Console.WriteLine("Example #1: IndexOf(string[, startIndex][,count]) ")
 
        Dim strIndexOfExample As String = "This is a test string"
 
        Console.WriteLine(strIndexOfExample.IndexOf("is")) 'Returns 2
 
        Console.WriteLine(strIndexOfExample.IndexOf("xyz")) 'Returns -1 (not found)
 
        'write blank line to make output easier to read
        Console.WriteLine()
 
        'Prevent console from closing before you press enter

Module Module1
 
    Sub Main()
 
 
        Dim myclsIndexOf As New clsIndexOf
        myclsIndexOf.Main()
 
 
 
    End Sub
