How to generate mdx query using C#

Question

I am new to mdx query and i am very curious about mdx query generation using c# so i searched for any demo or open source then i found
Ranet.olap, which is providing what i need. After taking the dlls i tried to incorporate them in my code. I am pasting my full
console code which should generate mdx query but it's not doing so, Am i doing something wrong.
using System;
using System.Collections.Generic;
using Microsoft.AnalysisServices.AdomdClient;
using Ranet.Olap.Core.Managers;
using Ranet.Olap.Core.Metadata;
using Ranet.Olap.Core.Types;

Hi mkm1,
According to your description, you want to use C# code to generate MDX Query. Right?
In Analysis Servcies, we just need to use "Microsoft.AnalysisServices.AdomdClient.dll" to open connection to SSAS database and retrieve data from cube. Here are some sample code about executing MDX query using C#.
Dim objConnection As New AdomdConnection("Data Source=localhost;Initial Catalog=Adventure Works DW 2008;")
Dim objCommand As New AdomdCommand()
Dim objDatatable As New DataTable
Dim strCommand As String
strCommand = "SELECT [Measures].[Internet Sales Amount] ON COLUMNS, "
strCommand = strCommand & " [Date].[Calendar].[Calendar Year] ON ROWS"
strCommand = strCommand & " FROM [Adventure Works]"
objConnection.Open()
objCommand.Connection = objConnection
objCommand.CommandText = strCommand
Dim objDataAdapter As New AdomdDataAdapter(objCommand)
objDataAdapter.Fill(objDatatable)
objConnection.Close()
Since your code is more related to a third party API, we suggest you post your question to Rnet.
Reference:
Microsoft.AnalysisServices.AdomdClient Namespace
