示例1: AssemblyVersion
' 導入命名空間
Imports System.Reflection
<Assembly: AssemblyVersion("1.0.0.0")>
Public Class StringLibrary
Public Shared Function SubstringStartsAt(fullString As String, substr As String) As Integer
Return fullString.IndexOf(substr, StringComparison.Ordinal)
End Function
End Class示例2: Main
Public Module Example
Public Sub Main()
Dim value As String = "The archaeologist"
Dim substring As String = "archæ"
Dim position As Integer = StringLibrary.SubstringStartsAt(value, substring)
If position >= 0 Then
Console.WriteLine("'{0}' found in '{1}' starting at position {2}",
substring, value, position)
Else
Console.WriteLine("'{0}' not found in '{1}'", substring, value)
End If
End Sub
End Module輸出：
archæ' not found in 'The archaeologist'
