you r wrong
using is not equal “引用“
using just help you to ellipise the word but not add the component to you project
and “引用“ can
for example
if you have “引用“ the System.Data
you can using System.Data and use DataTable directly or don't using System.Data but use System.Data.DataTable
if you don't “引用“ the System.Data
you can't do anything about the System.Data

我以前就是这样理解的。
只是现在都一个劲的using,没有quote,所以产生了误解.
主要是我using的东西都是系统默认quote的东西里已经包含的了.
