如何使用C＃序列化avro自定义对象列表？

Question

我在https://codepaste.net/mngm23下找到了关于C＃的avro示例：

{
    "type": "record",
    "name": "Person",
    "fields": [
        { "name": "name", "type": "string" },
        { "name": "address", 
          "type": {
            "type": "record",
                "name": "Address",
                "fields": [
                    { "name": "address", "type": "string" },
                    { "name": "zipcode", "type": "string" }]
            }
        }
    ]
}

插入项目的C＃代码如下所示：

        var schema = RecordSchema.Parse(schemaStr) as RecordSchema;

        // pick out the address schema so we can assign to that
        var addrSchema = schema["address"].Schema as RecordSchema;

        var person = new Generic.GenericRecord(schema);
        person.Add("name", "RIck");
        person.Add("age", 45);
        person.Add("company", "West Wind");

        // create a child record
        var address = new GenericRecord(addrSchema);
        address.Add("address", "32 Kaiea");
        address.Add("zipcode", "96779");

        person.Add("address", address);     

        var st = new FileStream(STR_Ctempavrobin,FileMode.OpenOrCreate,FileAccess.Write,FileShare.Write);

        Avro.IO.Encoder enc = new BinaryEncoder(st);
        var dwr = new Generic.DefaultWriter(schema);

        dwr.Write<GenericRecord>(person, enc);
        st.Close();

我无法弄清楚，如何调整架构和csharp代码来实现＆＃34;地址＆＃34;一系列的地址。我试过跟随，但我没有设法获得adressesList模式。

{
    "type": "record",
    "name": "Person",
    "fields": [
        { "name": "name", "type": "string" },
        { "name": "addressList", 
          "type": "array",
          "items" : {
                "type": "record",
                "name": "Address",
                "fields": [
                    { "name": "address", "type": "string" },
                    { "name": "zipcode", "type": "string" }]

            }
        }
    ]
}

如何在C＃中向数组添加项目呢？
