Keyboard shortcut for Jumping between "If/End If"

I know it's simple to do in C#, but what is the command to jump between If/End If marks in VB.Net like you can jump between braces in C#? (C#-version of this Question: Go to Matching Brace in Visual Studio?) If you're using Visual Studio 2010, you can use Ctrl+Shift+Up and Ctrl+Shift+Down to jump between highlighted references and keywords. Since these are If blocks, the IDE will hi

在“If / End If”之间跳转的键盘快捷键

我知道在C#中做这件事很简单,但是在If / End之间跳转的命令是什么如果您可以在C#中的大括号之间跳转,那么VB.Net中的标记是什么? (这个问题的C#版本:转到Visual Studio中匹配Brace?) 如果您使用的是Visual Studio 2010,则可以使用Ctrl + Shift + Up和Ctrl + Shift + Down在突出显示的引用和关键字之间跳转。 由于这些是If块,IDE也会突出显示Then关键字,因此只需快速连续两次点击向上/向下。 上/下环绕,所以

这个Catch声明有什么意义?

我在旧版代码中看到了这一点。 如果有的话,单个投掷的目的是什么? Try 'Some Oracle access statement Catch err As OracleClient.OracleException Throw Finally 'Do something End Try 结果是否与原始错误未被捕获一样? 您会使用Throw语句不带参数来重新抛出原始错误,通常是在首先执行某些操作之后? 它看起来像是用来冒泡的错误。 虽然在这种情况下
