我正在使用MongoDB C#驱动程序。 我在C#中有一个数据结构
public class ResourceSpec
{
public string TypeName
{
get;
private set;
}
public HashSet<ResourceProperty> Properties
{
get;
private set;
}
}
public class ResourceProperty
{
public string Val
{
get;
private set;
}
}
我希望将其序列化为:
{TypeName: 'blabla', Properties: ['value1', 'value2', 'value3' ]}
而不是
{TypeName: 'blabla', Properties: [{Val: 'value1'}, {Val: ' value2'}, {Val: ' value3'}] }
我该怎么做?

您可以编写自定义序列化程序并将其注册到驱动程序。有一点需要注意,一旦注册了序列化程序,它将用于每个ResourceSpec
实例。
public class ResourceSpecSerializer : BsonBaseSerializer
{
public override object Deserialize(BsonReader bsonReader, Type nominalType, Type actualType, IBsonSerializationOptions options)
{
// Deserialize logic
}
public override void Serialize(BsonWriter bsonWriter, Type nominalType, object value, IBsonSerializationOptions options)
{
// Serialize logic
}
使用BsonSerializer.RegisterSerializer
BsonSerializer.RegisterSerializer(typeof(ResourceSpec), new ResourceSpecSerializer());
为了实现自定义JSON,我建议调查Json.NET
,特别是JsonWriter
以下是使用JsonWriter
:
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
using(JsonWriter writer = new JsonTextWriter(sw))
{
writer.Formatting = Formatting.Indented;
writer.WriteStartObject();
writer.WritePropertyName("CPU");
writer.WriteValue("Intel");
writer.WritePropertyName("PSU");
writer.WriteValue("500W");
writer.WritePropertyName("Drives");
writer.WriteStartArray();
writer.WriteValue("DVD read/writer");
writer.WriteComment("(broken)");
writer.WriteValue("500 gigabyte hard drive");
writer.WriteValue("200 gigabype hard drive");
writer.WriteEnd();
writer.WriteEndObject();
}
将显示:
{
"CPU": "Intel",
"PSU": "500W",
"Drives": [
"DVD read/writer"
/*(broken)*/,
"500 gigabyte hard drive",
"200 gigabype hard drive"
]
}
