No need to do anything. The garbage collector will do its jobs clearing the variable. Explicitly set every variable to nothing will slow down your application.
不需要做任何事情。垃圾收集器将完成清除变量的工作。将每个变量显式设置为空会减慢您的应用程序的速度。

You can always set it to Nothingwhich will clear the reference. Then the garbage collector will take care of the rest when it finds that to be a good idea.
您始终可以将其设置为Nothing清除引用。然后垃圾收集器会在它发现这是一个好主意时处理剩下的事情。
split = Nothing
However, if this is a local variable of a method you would typically not need to worry about this, the array will be available for garbage collection as soon as it goes out of scope.
但是，如果这是一个方法的局部变量，您通常不需要担心这一点，一旦超出范围，该数组将可用于垃圾收集。
