SharePoint 2010:Accessing All Document In a Document Library Irrespective of the folder structure

The other day I was required to write a method that would return  a datatable filled with all the documents in a particular document Library irrespective of the folders insider that specific Doc Lib.
I took a slightly different approach than I usually take, since I did not have to consider the folder and instead all the files inside.  So I  used a CAML query  as follows

Query.ViewAttributes = "Scope=\"Recursive\"";

Following is the method that takes customer ID a paramter and returns all the document against it. The method eventually turned very complex as there were a lot features such SharePoint NTLM security token, property bags and the Mime types were coded. But here is the simplest version:

public DataTable GetListofDocuments(string cusID)
        {
            DataTable dtFiles = new DataTable("Documents");
            dtFiles.Columns.Add("Url", typeof(string));
            dtFiles.Columns.Add("FileName", typeof(string));
            dtFiles.Columns.Add("FileSize", typeof(int));
            dtFiles.Columns.Add("Modified", typeof(DateTime));
            dtFiles.Columns.Add("IsSecure", typeof(bool));
               

            if (cusID == string.Empty)
            {
                throw new Exception();
            }
            string docPath = "MyDocLib";
         
            using (SPSite site = new SPSite("http://vhyder"))
            {
                using (SPWeb oWebsite = site.OpenWeb())
                {
                    try
                    {

                        SPList oList = oWebsite.Lists[docPath];
                     
                        SPView oView = oList.Views[docLibView];

                        SPQuery oQuery = new SPQuery(oView);

                        oQuery.ViewAttributes = "Scope=\"Recursive\"";
                        SPListItemCollection collListItemsAvailable = oList.GetItems(oQuery);

                        foreach (SPListItem oListItemAvailable in collListItemsAvailable)
                        {

                            if (oListItemAvailable[colCustomer] != null && oListItemAvailable[colCustomer].ToString() != string.Empty)
                            {
                                string customerID = oListItemAvailable[colCustomer].ToString();
                                if (customerID == cusID)
                                {
                                    string[] docNameSlices = oListItemAvailable.Name.ToString().Split('.');
                                 
                                    dtFiles.Rows.Add(oListItemAvailable.Url, oListItemAvailable.Name, oListItemAvailable.File.Length, oListItemAvailable["Modified"], oListItemAvailable["IsSecure"]);
                                }
                            }
                        }

                    }
                    catch (Exception)
                    {
                        throw;
                    }

                }
            }
            return  dtFiles;

        }
