我有一個相當詳細的XML我已經能夠解析它的大部分,但即時通過一棵樹,只是讓我難倒,害怕我正在努力,然後它需要。 這裏是我所指的XML。解析XML到列表中

我想結束一個列表將看起來像這樣。
Account distributionType Activity distributionValue Fund
7200 PercentOfPrice "" 10 360806
7200 PercentOfPrice "" 45 360903
7200 PercentOfPrice "" 45 360957
等等
我寫的代碼看起來是這樣的。這是一個片段。介意你我認爲我已經完成了這一切。

// Create another reader that contains just the accounting elements.
XmlReader inner = reader.ReadSubtree();
//inner.ReadToDescendant("Codes");
//printOutXML(inner);

{
//walk down the xml hiearchy then simply fill in the values.
case XmlNodeType.Element:
switch (reader.Name)

//get the attribute that we are currently working with such as account and
innerTagName=inner.GetAttribute("name");

//and if it is i will immediate assign the activity list a set of empty quotes.

在標籤distributionType我需要做的名單長度只要在列表帳戶,換句話說,一旦我有它的一個變量,我需要用它作爲填充物,使的情況下,分配類型列表與賬戶列表一樣大。 我無法想象有沒有更簡單的方法來做到這一點我一直在看linq到XML,但它沒有多大意義。我很想聽聽你們中的一些專家如何解決這個問題。我試圖用少一點的代碼來組合一個優雅的解決方案。 任何幫助將不勝感激。
作爲第一個問題,你爲什麼不走反序列化XML成類,但解析自己的XML的路線? – 2014-10-29 13:18:23
bernd我是一個noob與xml工作。我得到一個XML文件,我打開並處理該文件。最後,我必須創建一個數組列表插入到數據庫表中。反序列化的XML可能是最好的選擇,但在這一點上,我不知道更好。 – Miguel 2014-10-29 13:22:56
給我一點,我會爲你輸入一些東西。在此期間看看[本文]中的答案和鏈接(http://stackoverflow.com/questions/26257041) – 2014-10-29 13:26:20
