</SPAN>&nbsp;<BR>当我们把一个应用程序移植到一个包装在名字空间中的新版本时，using指示符非常 <SPAN class=copyctrl 
style="FONT-SIZE: 0pt">^# zh;h/ 
</SPAN>&nbsp;<BR>有用，但是使用多个using指示符会引起全局名字空间污染问题。 <SPAN class=copyctrl 
style="FONT-SIZE: 0pt">}V.p ax 
</SPAN>&nbsp;<BR>用多个选择性的using声明来代替using指示符会使这个问题最小化，由多个using <SPAN 
class=copyctrl style="FONT-SIZE: 0pt">u#WcwMUP 
</SPAN>&nbsp;<BR>声明引起的二义性的错误在声明点就能被检测到，因此建议使用using声明而不是 <SPAN class=copyctrl 
style="FONT-SIZE: 0pt">yU l ; 
</SPAN>&nbsp;<BR>using指示符,以便更好地控制程序中地全局名字空间污染问题。 <SPAN class=copyctrl
