Examples

IF the user enters a 00001 the count would be 4

If the user enters a 0811 the count would be 1

How would i do this?

Answer 1

The most efficient way is to simply loop through the characters of the string and count each character that is a 0 until your read a non 0 character.

I do not use VB.NET much, so this is just some rough VBish pseudo code

Dim myString As String = "00001"
Dim count As Integer = 0
For Each c As Char In myString
  If C = "0"c Then
    count += 1
  Else
    Exit For
  End If
