Look at (and read) the documentation for the String class and see if there is a method you could use to do this. I would suggest the Split method myself....

Use String.Split method[^].

Solution 1

You can use String.Split Method (System)[^]

Consider the following example

VB

Dim input As String
Dim elements As String()

input = "Lebron King James"

elements = input.Split(" ")
For Each item As String In elements
    Console.WriteLine(item)
Next

Output would be

Lebron
King
James

If you look at the documentation (string functions), you will see that left is not the only function to cut strings.

How do you define "first,last and middle part of the string" in

i want to get the "Lebron","King","James" separately .

Look for common traits shared by the result that you want and I noticed they are double-quoted individually, then call Regex to extract them. See example:

Imports System
Imports System.Text.RegularExpressions

Public Module Module1

    Public Sub Main()
        Dim str As String = "i want to get the ""Lebron"",""King"",""James"" separately."
		Console.Write("The sentence is: ")
		Console.WriteLine(str)
		Dim pattern As String = "(?<="")[^,""]+(?="")"
		Console.Write("The Regex pattern is: ")
        Console.WriteLine(pattern)

		showMatch(str, pattern)
		
    End Sub

    Sub showMatch(ByVal text As String, ByVal expr As String)
        Dim mc As MatchCollection = Regex.Matches(text, expr)
        Dim m As Match
		
		Console.WriteLine("The matched are as follows: ")
        For Each m In mc
            Console.WriteLine(m)
        Next m
    End Sub
End Module

The result as shown:

The sentence is: i want to get the "Lebron","King","James" separately.
The Regex pattern is: (?<=")[^,"]+(?=")
The matched are as follows: 
Lebron
King
James
