YamlDotNet 是一个用于处理 YAML 格式数据的 .NET 库。反序列化是将 YAML 数据转换为 .NET 对象的过程。对于静态属性的反序列化,需要注意以下几点:
静态属性属于类本身,而不是类的实例。因此,在反序列化时,默认情况下 YamlDotNet 不会处理静态属性。
要反序列化静态属性,可以使用自定义的 IYamlTypeResolver
或 IYamlConverter
。以下是一个示例代码:
using System;
using YamlDotNet.Serialization;
using YamlDotNet.Serialization.NamingConventions;
public class MyClass
{
public static string MyStaticProperty { get; set; }
[YamlIgnore]
public string NonStaticProperty { get; set; }
}
public class StaticPropertyConverter : IYamlConverter
{
public bool Accepts(Type type)
{
return type == typeof(MyClass);
}
public object ReadYaml(IParser parser, Type type)
{
var node = parser.Current;
parser.MoveNext();
var serializer = new SerializerBuilder()
.WithNamingConvention(CamelCaseNamingConvention.Instance)
.Build();
var instance = new MyClass();
serializer.Deserialize(new StringReader(node.ToString()), instance);
// 手动设置静态属性
if (node is YamlMappingNode mappingNode)
{
foreach (var kv in mappingNode.Children)
{
if (kv.Key.ToString() == "MyStaticProperty")
{
MyClass.MyStaticProperty = kv.Value.ToString();
}
}
}
return instance;
}
public void WriteYaml(IParser parser, IYamlWriter writer, object value)
{
throw new NotImplementedException();
}
}
class Program
{
static void Main()
{
var yaml = @"
MyStaticProperty: StaticValue
NonStaticProperty: NonStaticValue";
var deserializer = new DeserializerBuilder()
.WithConverter(new StaticPropertyConverter())
.Build();
var obj = deserializer.Deserialize<MyClass>(yaml);
Console.WriteLine(MyClass.MyStaticProperty); // 输出: StaticValue
Console.WriteLine(obj.NonStaticProperty); // 输出: NonStaticValue
}
}
通过自定义转换器,可以在反序列化过程中手动处理静态属性。这样可以确保静态属性也能正确地从 YAML 数据中读取。
