Try Catch语句realBasic

Question

我正在尝试在try catch中包装简单的语句。问题是，我能够找到的所有例子都谈到了预先定义的错误。

我需要一个通用的错误，类似于C#中的try/catch。

Answer 1

对于一般的try catch，您可以这样做：

try

  ...put some code here

catch

  ...do something for ANY exception here.

finally

  ...code here that runs IF an exception occurs

end try

catch部分有可选的参数来捕获某些类型的错误(如您所见的例子)。第一段给出了http://docs.xojo.com/index.php/Try中的定义

Try

// Your code

Catch [ErrorParameter] [As ErrorType]

//exception handlers

[ Finally ]

//code that executes even if runtime exceptions were raised

End [Try]
