DataTable into Pipe Sepeated

DataTable Data as Pipe("|") Sepeated:

Its true that we will have many requirements specially when we want to share data between machines in http request/response , then we have to go for this technique:-----

  public object ReturnDataTableWithPipeSeparated() 
        {
            try
            {
                StringBuilder sb = new StringBuilder();
                DataSet ds = GetDatatoFillinDataSetIlyas()//fill your data
                int DsCount = ds.Tables.Count;
                for (int i = 0; i < ds.Tables.Count; i++)
                {
                    for (int j = 0; j < ds.Tables[i].Rows.Count; j++)
                    {
                        if (ds.Tables[i].Rows.Count > 0)
                        {
                            for (int k = 0; k < ds.Tables[i].Columns.Count; k++)
                            {
                                if (ds.Tables[i].Rows[j][k].ToString() != "")
                                {
                                    sb.Append(ds.Tables[i].Rows[j][k].ToString());
                                }
                                else
                                {
                                    sb.Append("\t");
                                }
                                if (k < ds.Tables[i].Columns.Count - 1)
                                    sb.Append('|');
                            }
                        }
                        sb.Append('\n');
                    }
                }
                return sb;
            }
            catch (Exception)
            {
                throw;
            }
        }
