String.GetEnumerator() method used to retrieve individual character from the string through each iteration. It gives better performance as compare to foreach loop and it is faster than foreach loop. Enumerator use to keep thing easy. GetEnumerator method defined by IEnumerable interface, it returns an IEnumerator interface.
Those collections implemented by IEnumerable that can be used with a foreach statement. Many of them have confusion in IEnumerator and IEnumerable. IEnumerator do its iteration over a non-generic collection and CharEnumerator implements both the non-generic IEnumerable and the generic IEnumerable<char> interfaces. To use string.GetEnumerator method you should add System.Collections.Generic namespace in your program.
Code
Module Module1
Sub Main()
Dim Str1 As String = "Welcome to "
Dim Enumerator As CharEnumerator = Str1.GetEnumerator()
While Enumerator.MoveNext()
Console.Write("{0}", Enumerator.Current)
End While
EnumerateAndDisplay("VB .Net Heaven")
Console.ReadLine()
End Sub
Function EnumerateAndDisplay(str2 As [String]) As String
Dim OperandEnum As IEnumerator = str2.GetEnumerator()
While OperandEnum.MoveNext()
Console.Write("{0}", OperandEnum.Current)
End While
Return str2
End Function
End Module
