VB.NET 的隐藏功能? [英] Hidden Features of VB.NET?

问题描述

我通过浏览隐藏功能学到了很多的 C# 并且当我找不到某些东西时感到惊讶与 VB.NET 类似.

I have learned quite a bit browsing through Hidden Features of C# and was surprised when I couldn't find something similar for VB.NET.

那么它有哪些隐藏的或鲜为人知的功能?

So what are some of its hidden or lesser known features?

推荐答案

Exception When 子句在很大程度上是未知的.

The Exception When clause is largely unknown.

考虑一下:

Public Sub Login(host as string, user as String, password as string, _
                            Optional bRetry as Boolean = False)
Try
   ssh.Connect(host, user, password)
Catch ex as TimeoutException When Not bRetry
   ''//Try again, but only once.
   Login(host, user, password, True)
Catch ex as TimeoutException
   ''//Log exception
End Try
End Sub
