示例1: StringParsing
Module StringParsing
Public Sub Main()
TryToParse(Nothing)
TryToParse("16051")
TryToParse("9432.0")
TryToParse("16,667")
TryToParse(" -322 ")

End Sub
Private Sub TryToParse(value As String)
Dim number As Int16
Dim result As Boolean = Int16.TryParse(value, number)

Console.WriteLine("Converted '{0}' to {1}.", value, number)
Else
If value Is Nothing Then value = ""
Console.WriteLine("Attempted conversion of '{0}' failed.", value)
End If
End Sub
End Module输出：
