vb.net中的SQLexception

Question

我在SQL数据库中有两个表。一个表引用另一个表。

我在VB.NET程序的表中添加数据。我想写一个try...catch块来捕获SQLException，同时向可能发生Foreign Key违规的表中添加数据。我该怎么写呢？

Answer 1

您可以尝试使用此代码

Try
  ...

Catch ex As Exception
   MsgBox("Your exception" & ex.Message)
End Try

Answer 2

 Try
      'Do your stuff
 Catch ex as SqlException
      Dim errors = ex.Errors
      ' inspect errors to decide if this is the condition you want to catch
      Dim shouldCatch As Boolean = ... 
         ' Code that acts on the specific error condition
      If shouldCatch Then
      Else
         Throw ' rethrow everything we're not interested in
      End If
 End Try
