在我看来，您必须阅读的配置不需要XmlSerializer。 System.Configuration 为您提供的所有工具都绰绰有余。这里我重写了你的配置类（基本结构）：
public class DepartmentsConfiguration : ConfigurationSection
{
[ConfigurationProperty("departments", IsRequired = false, IsDefaultCollection = true)]
public DepartmentItemCollection Departments
{
get
{
var departments = this["departments"] as DepartmentItemCollection;
return departments;
}
set
{
this["departments"] = value;
}
}
}
[ConfigurationCollection(typeof(DepartmentItemCollection), AddItemName = "department")]
public class DepartmentItemCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new Department();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((Department)element).Name;
}
}
public class Department : ConfigurationElement
{
[ConfigurationProperty("id", IsRequired = false, IsKey = true)]
public int Id
{
get
{
return (int)(this["id"]);
}
set
{
this["id"] = value;
}
}
[ConfigurationProperty("name", IsRequired = true, IsKey = true, DefaultValue = "")]
public string Name
{
get
{
return (string)(this["name"]);
}
set
{
this["name"] = value;
}
}
[ConfigurationProperty("products", IsRequired = false, IsKey = false, IsDefaultCollection = false)]
public ProductCollection Products
{
get
{
return (ProductCollection)this["products"];
}
set
{
this["products"] = value;
}
}
}
[ConfigurationCollection(typeof(ProductCollection), AddItemName = "product")]
public class ProductCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new Product();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((Product)element).Name;
}
}
public class Product : ConfigurationElement
{
[ConfigurationProperty("name", IsRequired = true, IsKey = true, DefaultValue = "")]
public string Name
{
get
{
return (string)(this["name"]);
}
set
{
this["name"] = value;
}
}
[ConfigurationProperty("price", IsRequired = false)]
public decimal Price
{
get
{
return (decimal)(this["price"]);
}
set
{
this["price"] = value;
}
}
[ConfigurationProperty("", IsRequired = false, IsKey = false, IsDefaultCollection = true)]
[ConfigurationCollection(typeof(KeyValueConfigurationCollection), AddItemName = "add")]
public KeyValueConfigurationCollection Items
{
get
{
var items = base[""] as KeyValueConfigurationCollection;
return items;
}
set
{
base[""] = value;
}
}
}
App.config 中的<configSections>：
<configSections>
<section
name="departmentConfiguration"
type="Test.DepartmentsConfiguration, Test"
allowLocation="true"
allowDefinition="Everywhere"
/>
</configSections>
<departmentConfiguration>
<departments>
<department id="1" name="Sporting Goods">
<products>
<product name="Basketball" price="9.99">
<add key="Color" value="Orange" />
<add key="Brand" value="[BrandName]" />
</product>
</products>
</department>
</departments>
</departmentConfiguration>
以及如何使用ConfigurationManager阅读它：
DepartmentsConfiguration config = (DepartmentsConfiguration) ConfigurationManager
.GetSection("departmentConfiguration");
foreach (Department department in config.Departments)
{
Console.WriteLine($"{department.Id}, {department.Name}");
foreach (Product product in department.Products)
{
Console.WriteLine($"{product.Name}, {product.Price}");
foreach (string key in product.Items.AllKeys)
{
Console.WriteLine($"{key} -> {product.Items[key].Value}");
}
}
}
我知道这与您的问题不一致，请作为个人建议。
