vb.net - 抛出异常后如何继续运行代码？

Question

我想知道是否有办法让程序在抛出异常后继续执行。例如:

Try
  line 1
  line 2
  line 3
  line 4 ' (here the exception is thrown and jumps to the catch)
  line 5 ' <-- I would like the program to continue its execution, logging the error
  line 6  

Catch ex as Exception
   log(ex.tostring)
End Try

Answer 1

如果您正在做一些知道如何恢复或不重要的事情，则应该使用特定的 catch 将该行包装在 try/catch 中。例如

Try 
  line 1
  line 2
  line 3
  Try
     line 4 ' (here the exception is throw and jumps to the catch)
  Catch iox as IOException ' or whatever type is being thrown
     'log it
  End Try
  line 5  ' <-- I would like the program to continue its execution after logging the error
  line 6  

Catch ex as Exception
   log(ex.tostring)
End Try
