You would throw a new exception.
你会抛出一个新的异常。
Have a look at Throw Statement (Visual Basic)
The Throw statement throws an exception that you can handle with structured exception-handling code (Try...Catch...Finally) or unstructured exception-handling code (On Error GoTo). You can use the Throw statement to trap errors within your code because Visual Basic moves up the call stack until it finds the appropriate exception-handling code.
Throw 语句抛出一个异常，您可以使用结构化异常处理代码 (Try...Catch...Finally) 或非结构化异常处理代码 (On Error GoTo) 来处理该异常。您可以使用 Throw 语句来捕获代码中的错误，因为 Visual Basic 会向上移动调用堆栈，直到找到合适的异常处理代码。
