DataSet case sensitive issue
今天系統(tǒng)進(jìn)行了單元測(cè)試發(fā)現(xiàn)一個(gè)bug，不知道怎么回事。我們整個(gè)小組花費(fèi)了半天時(shí)間終于找到了問題所在，就是：DataSet case sensitive
原以為在DataSet.Tables.Add(new DataTable(string strTableName))時(shí)，是可以隨便的，沒有想到就是這個(gè)東西發(fā)生了問題。google 了一下，發(fā)現(xiàn)這篇文章：

突然大夢(mèng)清醒，原來Dataset 也是 case sensitive (大小寫敏感)的。查詢MSDN 中關(guān)于 Dataset 的說明，有這么一段：
http://msdn2.microsoft.com/en-us/library/system.data.dataset.aspx
Whereas DataTable objects contain the data, the DataRelationCollection allows you to navigate though the table hierarchy. The tables are contained in a DataTableCollection accessed through the Tables property. When accessing DataTable objects, note that they are conditionally case sensitive. For example, if one DataTable is named "mydatatable" and another is named "Mydatatable", a string used to search for one of the tables is regarded as case sensitive. However, if "mydatatable" exists and "Mydatatable" does not, the search string is regarded as case insensitive. For more information about working with DataTable objects, see Creating a DataTable.
其它的先不管了，我就看到了對(duì)case? sensitive 的描述：
如果 DataSet 中包含名為 "mydatatable" 和另一個(gè) "Mydatatable"時(shí)，在使用表查詢時(shí)，Dataset 是大小寫敏感的，如果只包含一個(gè) "mydatatable" ，則又不是大小寫敏感的。
看到這里，才發(fā)現(xiàn)原來是對(duì)DataSet 的標(biāo)操作時(shí)出現(xiàn)了問題。更改后一切ok。
總結(jié)
以上是生活随笔為你收集整理的DataSet case sensitive issue的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
