说明:1,这个操作COM首先要引用一个COM交互操作RWC,首先要添加引用DiskQuotaTypeLibrary.

2,要在ASP.NET中的顶部加入<%@ Page language="c#" aspcompat="true"%>

3,如果要在ASP.NET中操作COM,要有足够的权限,而ASP.NET这个用户的权限是不够的,所以要在web.config中加入这行 ,当然你也可以用其它的方式来授予权限.

4,OK,告一段落先.<%@ Page language="c#" aspcompat="true" AutoEventWireup="false" %><%@ Page language="c#" aspcompat="true" AutoEventWireup="false" %><%@ Page language="c#" aspcompat="true" AutoEventWireup="false" %>
