所有内容都正确导入，日志文件为:

Colonist 2 Shirt Color Before: 0, 0, 1, 1
Colonist 2 Coat Color Before: 0, 0, 1, 1
但是当我用这段代码重新检查值时:
private static void VerifyLoad()
{
for (int i = 0; i < ColonistManager.Population.Count; i++)
{
Log.Message("Colonist " + i.ToString() + " Shirt Color After: " + ColonistManager.Population[i].Clothing[0].Color.r.ToString() + ", " + ColonistManager.Population[i].Clothing[0].Color.g.ToString() + ", " + ColonistManager.Population[i].Clothing[0].Color.b.ToString() + ", " + ColonistManager.Population[i].Clothing[0].Color.a.ToString());

}
}
日志显示:
Colonist 0 Shirt Color After: 0, 0, 1, 1
Colonist 0 Coat Color After: 1, 0, 0, 1
Colonist 1 Shirt Color After: 0, 0, 1, 1
Colonist 1 Coat Color After: 0, 0, 1, 1
Colonist 2 Shirt Color After: 0, 0, 1, 1
Colonist 2 Coat Color After: 0, 0, 1, 1
我完全不明白为什么变量会突然改变，所以任何帮助都会非常感激!
大多数情况下，可以简单地使用XmlSerializer从Xml转换为对象。在您的例子中，Xml不太适合自动序列化，因为在具有相同名称但不同属性的类似元素(例如:BasicInfo、Graphics元素)和具有多个值的属性(例如:所有Color属性)中使用了不规则的约定。因此，像您所做的那样手动解析似乎是处理这种特定Xml的最佳方法。
但是，您遇到的问题是在解析逻辑中。如果您清理了解析逻辑，可能会更容易发现问题。一个庞大的递归方法和一堆if语句将很难调试。
考虑使用访问者模式重写解析逻辑。您的代码将更容易维护和修改。下面是如何在特定Xml上使用访问者模式的示例。当我运行这个程序时，我得到了预期的结果。
static void Main()
{
List<Colonist> colonists = Parse();
for (int i = 0; i < colonists.Count; i++)
{
Console.WriteLine("Colonist " + i.ToString() + " Shirt Color After: " + colonists[i].Clothing[0].Color.R.ToString() + ", " + colonists[i].Clothing[0].Color.G.ToString() + ", " + colonists[i].Clothing[0].Color.B.ToString() + ", " + colonists[i].Clothing[0].Color.A.ToString());
Console.WriteLine("Colonist " + i.ToString() + " Coat Color After: " + colonists[i].Clothing[1].Color.R.ToString() + ", " + colonists[i].Clothing[1].Color.G.ToString() + ", " + colonists[i].Clothing[1].Color.B.ToString() + ", " + colonists[i].Clothing[1].Color.A.ToString());
}
}
private static List<Colonist> Parse()
{
List<Colonist> colonists = new List<Colonist>();
using (XmlTextReader reader = new XmlTextReader(File.OpenRead("XMLFile1.xml")))
{
while (reader.Read())
{
switch (reader.Name)
{
case "Colonist":
var colonist = VisitColonist(reader);
colonists.Add(colonist);
break;
}
}
}
return colonists;
}
private static Colonist VisitColonist(XmlTextReader reader)
{
Colonist colonist = new Colonist();
while (reader.Read())
{

break;

}
return colonist;
}
private static void VisitBasicInfo(XmlTextReader reader, Colonist colonist)
{

{
switch(reader.Name)
{
case "Name":
var parts = reader.Value.Split(' ');
colonist.FirstName = parts[0];
colonist.NickName = parts[1];
colonist.LastName = parts[2];
break;
case "Age":
colonist.Age = Int32.Parse(reader.Value);
break;
}
}
}
private static void VisitOnSkin(XmlTextReader reader, Colonist colonist)

private static Color GetColor(string colorValue)

R = Single.Parse(parts[0]),
G = Single.Parse(parts[1]),
B = Single.Parse(parts[2]),
A = Single.Parse(parts[3])
};
return color;
}
我只是解析了文件的一部分。下面是我使用的类:
public class Colonist

public string FirstName { get; set; }
public string NickName { get; set; }
public string LastName { get; set; }
public int Age { get; set; }
public Clothing[] Clothing { get; set; }

public class Clothing

public class Color

}
