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。

3、第一个程序

 

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
    }
