Cube processing problem

I want to use SSAS cube to get data from Dynamics AX and Pass data to wpf Devexpress PivotGrid.
I am using following order in AX to create cube:
Perspective–>View–>Query(with arguments)
Now when I change the arguments of query everytime I have to Process the cube manually and render the data.
I want that process to be done through c# code automatically.
i had tried below code

Server server = new Server();

    Database database = server.Databases.FindByName(databaseName);
    Cube cube = database.Cubes.FindByName(cubeName);


but it is not working.

Can anyone help??
