需要帮助清理我的XML解析器代码

因此，我正在努力熟悉XML。为了做到这一点，我创建了一个简单的XML文件，之后我创建了C#脚本来读取该XML文件。现在一切都按预期工作，但代码感觉相当糟糕。

我的XML如下所示：

<buildings>
    <building>
        <name>House</name>
        <buildTime>5</buildTime>
        <treeCost>100</treeCost>
        <stoneCost>10</stoneCost>
        <goldCost>10</goldCost>
    </building>
    <building>
        <name>Tower</name>
        <buildTime>5</buildTime>
        <treeCost>10</treeCost>
        <stoneCost>300</stoneCost>
        <goldCost>50</goldCost>
    </building>
</buildings>

我的C#代码是这样的：

    XDocument xmlDoc = XDocument.Load ("BuildingGame_Data/Buildings.xml");
    var names = xmlDoc.Descendants("building").Descendants("name");
    var buildTimes = xmlDoc.Descendants("building").Descendants("buildTime");
    var treeCosts = xmlDoc.Descendants("building").Descendants("treeCost");
    var stoneCosts = xmlDoc.Descendants("building").Descendants("stoneCost");
    var goldCosts = xmlDoc.Descendants("building").Descendants("goldCost");
    List<string> namesList = new List<string>();
    List<int> buildTimesList = new List<int>();
    List<int> treeCostsList = new List<int>();
    List<int> stoneCostsList = new List<int>();
    List<int> goldCostsList = new List<int>();
    foreach (string n in names)
    {
        namesList.Add(n);
    }
    foreach (string b in buildTimes)
    {
        buildTimesList.Add(System.Convert.ToInt32(b));
    }
    foreach (string t in treeCosts)
    {
        treeCostsList.Add(System.Convert.ToInt32(t));
    }
    foreach (string s in stoneCosts)
    {
        stoneCostsList.Add(System.Convert.ToInt32(s));
    }
    foreach (string g in goldCosts)
    {
        goldCostsList.Add(System.Convert.ToInt32(g));
    }

    List<Building> buildings = new List<Building>();
    for (int i = 0; i < namesList.Count; i++)
    {
        buildings.Add(new Building(namesList[i], buildTimesList[i], treeCostsList[i], stoneCostsList[i], goldCostsList[i]));
    }

现在，我想用一种方法跳过中间部分，在那里我转换所有的XML数据并将其存储在不同的列表中。这似乎是一个不必要的步骤，但我没能以任何其他方式让它发挥作用。

var buildings = xmlDoc.Descendants("building")
                      .Select(be => new Building (
                          (string)be.Element("name"),
                          (int)be.Element("buildTime"),
                          (int)be.Element("treeCost"),
                          (int)be.Element("stoneCost"),
                          (int)be.Element("goldCost")))
                      .ToList();
