SSAS系列——【08】多维数据（程序展现Cube）

1、引用DLL？

      按照之前安装的MS SQLServer的步骤安装完成后，发现在新建的项目中“Add Reference”时居然找不到Microsoft.AnalysisServices.AdomdClient命名空间，不知道是什么状况？只好添加DLL了，在“C:\Program Files\Microsoft.NET\ADOMD.NET\100\Microsoft.AnalysisServices.AdomdClient.dll”下找到了该文件，该文件的最后修改时间是2009年3月30日，534KB。如图：

2、连接字符串？

本人觉得这一块和ADO.NET没有太大的区别，此处我使用的连接字符串是：Provider=SQLNCLI10.1;Data Source=localhost;Integrated Security=SSPI;Initial Catalog=BPDW; ，该字符串可以在数据源设计器中找到，所以根本无需记忆，会找即可。
