试试Catch语句realBasic

Question

我正试图在try-catch中封装一个简单的语句。问题是，我能找到的所有例子都谈到了预定义的错误。

我需要一个通用错误，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部分有一些可选参数来捕获某些类型的错误（您已经看到的示例）。第一段给出的定义http://docs.xojo.com/index.php/Try

Try
// Your code
Catch [ErrorParameter] [As ErrorType]
//exception handlers
[ Finally ]
//code that executes even if runtime exceptions were raised
End [Try]
