与此处解决的问题有关：How to populate a Class with Dictionary using LINQ

我还有另一个问题是尝试填充Dictionary<ObjectType, float>，其中ObjectType是我创建的自定义枚举。

LootProfile.cs

public class LootProfile
{

    /*
    dynamicDrop multipli non definiti
    */
    public string name;

    public int dynamicDropNumber; //  = 3 
    public Dictionary<int, float> dynamicDrop;  // 70, 40, 10
    public Dictionary<ObjectType, float> dynamicType;
    public Dictionary<Rarity, float> dynamicDropRarity; // "Common" - 60, "Uncommon" - 26, "Rare" - 12, "Epic" - 2

    public int staticDropNumber; // = 2
    public Dictionary<int, Dictionary<int, float>> staticDrop;  // 0 - idPattern - prob

    public Faction faction;
    public Location location;
}

ImporterXML

var query = from item in xml.Root.Elements("LootProfile")
                select new LootProfile()
                {

                    name = (string)item.Attribute("name"),
                    dynamicDropNumber = (int)item.Element("dynamicDropNumber"),
                    dynamicDrop = item.Elements("dynamicDrop")
                        .Select((Item, Index) => new { Item, Index })
                        .ToDictionary(x => x.Index, x => float.Parse(x.Item.Value)),
                    dynamicType = item.Elements("dynamicTypeArmor")
                        .Select((Item, Index) => new { Item, Index })
                        .ToDictionary(x => x.Index, x => float.Parse(x.Item.Value))
                }
return query.ToList<LootProfile>();

我的问题是如何在Dictionary中导入XML元素的值

dynamicTypeArmor

dynamicTypeWeapon

dynamicTypeConsumable

在同一个词典中

ObjectType.Armor for dynamicTypeArmor

ObjectType.Weapon for dynamicTypeWeapon

ObjectType.Consumable for dynamicTypeConsumable

以下是如何做到这一点：

var query = xml.Elements("LootProfile")
    .Select(item => new LootProfile()
    {
        //...
        dynamicType =
            item.Elements()
                .Where(x => x.Name.LocalName.StartsWith("dynamicType"))
                .ToDictionary(
                    x => (ObjectType)Enum.Parse(
                        typeof(ObjectType),
                        x.Name.LocalName.Substring("dynamicType".Length)),
                    x => float.Parse(x.Value))
        //...
    });

您使用Where仅选择名称以＆＃34; dynamicType＆＃34;开头的元素，然后从数据中创建字典。

每个字典项的键是删除＆＃34; dynamicType＆＃34;后相应元素名称的其余部分。这将为你提供＆＃34;护甲＆＃34;，＆＃34;武器＆＃34;或＆＃34;消耗品＆＃34;。 Enum.Parse用于将这些字符串转换为Enum类型ObjectType。

每个字典项的值是解析为float的相应元素的值。
