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。

3、第一个程序

代码

string ReturnCommandUsingCellSet()    {        //Create a new string builder to store the results        System.Text.StringBuilder result = new System.Text.StringBuilder();        //Connect to the local server        using (AdomdConnection conn = new AdomdConnection("Provider=SQLNCLI10.1;Data Source=localhost;Integrated Security=SSPI;Initial Catalog=BPDW;"))        {            conn.Open();            //Create a command, using this connection            AdomdCommand cmd = conn.CreateCommand();            cmd.CommandText = @"select {[Measures].[Oil Proved Reserves]} on columns ,{[Dim Time].[年份].&[19]} on rows from [BPDW]where [Dim Geography].[国家名称].&[Total Asia Pacific]&[China]";            //Execute the query, returning a cellset            CellSet cs = cmd.ExecuteCellSet();            //Output the column captions from the first axis            //Note that this procedure assumes a single member exists per column.            result.Append("\t");            TupleCollection tuplesOnColumns = cs.Axes[0].Set.Tuples;            foreach (Microsoft.AnalysisServices.AdomdClient.Tuple column in tuplesOnColumns)            {                result.Append(column.Members[0].Caption + "\t");            }            result.AppendLine();            //Output the row captions from the second axis and cell data            //Note that this procedure assumes a two-dimensional cellset            TupleCollection tuplesOnRows = cs.Axes[1].Set.Tuples;            for (int row = 0; row < tuplesOnRows.Count; row++)            {                result.Append(tuplesOnRows[row].Members[0].Caption + "\t");                for (int col = 0; col < tuplesOnColumns.Count; col++)                {                    result.Append(cs.Cells[col, row].FormattedValue + "\t");                }                result.AppendLine();            }            conn.Close();            return result.ToString();        } // using connection    }
