SqlHelper.FillDataset 的一個Bug

　　這兩天在做數據查詢的時候在一個存儲過程對多表進行查詢分別填充到強類型的 DataSet 不同的表把存儲過程寫好以後使用 SqlHelperFillDataset 方法調用存儲過程發現的數據只有兩個表填上了而別的指定的表沒有填上數據跟蹤的時候發現DataSet 裡邊多了表也就是數據實際上填到 DataSet 了只是沒有填到指定的表
       於是懷疑是DataSet 表沒拖拽好重新拖拽後測試發現還是一樣的結果然後把存儲過程改成拼接 SQL 也不行但是如果自己使用 SqlDataAdapter 時就沒問題索性上網 google 了一下發現原來是 Data Access Application Block 中的一個Bug(《ADONET中的多數據表操作淺析之讀取》)
        希望以後有人碰到同樣問題 goole 一下別瞎忙乎了
