Simple DataAdapter doesnt work

My original code was working. Then my coworker made a change to the DAL and I have to use DBDataAdapter. I don't get an error with this piece of code BUT the dataset is not filled..skips the
dbAdapter.Fill(ds); line and goes to "finally" section. Not sure what's wrong.

My ****Orginal**** code was like this:
SqlDataAdapter myAdapter = new SqlDataAdapter();
           cmd.CommandType = CommandType.StoredProcedure;
                cmd.CommandText = "pSearchLastName";

                cmd.Parameters.Add("@name", SqlDbType.NVarChar).Value = cName;
                 conn.Open();

                try
                {
                    myAdapter.SelectCommand = cmd;
                    myAdapter.Fill(ds);
                   

****new code that doesnt work
 
using (DbConnection cn = this.Database.CreateConnection())
           {
               using (DbCommand cmd = this.Database.GetStoredProcCommand("pSearchLastName"))
               {
          
                   DbDataAdapter dbAdapter = null;
                     this.Database.AddInParameter(cmd, "@name", DbType.String, cName);
                
                   cn.Open();
            
                   try
                   {
 
                       cmd.Connection = cn;
                       dbAdapter.SelectCommand = cmd;
 
                       dbAdapter.Fill(ds); //** doesnt even get to here
                       foreach (DataRow row in ds.Tables[0].Rows)
                          ...

Object reference not set to an instance of an object

Do I need to create the DBAdapter??
// Create the DbDataAdapter.
            DbDataAdapter adapter = factory.CreateDataAdapter();
            adapter.SelectCommand = command;

In my original code i have:
SqlDataAdapter myAdapter = new SqlDataAdapter();

but cant do that with DbDataAdapter: DbDataAdapter dbAdapter = new DbDataAdapter();

>> what is "this.Database" as object?
I see this with this.Database ...trying it now...
DbDataAdapter dbAdapter = this.Database.GetDataAdapter();
