how to pass multiple classes as arguements :     public IEnumerable<Project> Get(int id)
		{
		   DataTable dt = new DataTable();
			Project_BL projbl = new Project_BL();
			dt = projbl.SelectprojectModelBasedProjectID(id);
			var tag = dt.AsEnumerable().Select(x => new TAGS
			{


				tag_id = x.Field<int>("tag_id"),
				tag_name = x.Field<string>("tag_name")

				// like wise initialize properties here
			});

			return tag;
		}

Here,in Ienumerable<Projects>,Projects is a class.I want another class to be added there. Also in var tag = dt.AsEnumerable().Select(x => new Projects,
here also  i want to add multiple class
