Question

我正在构建ServiceStack服务作为Windows Azure云网络角色。我正在尝试将具有类型为dynamic / ExpandoObject或DynamicTableEntity类的属性的数据/ DTO发布到我的服务方法，以便我可以编写一个通用方法来保存/从客户端获取任何类型的对象。此外，我的服务不知道客户端定义的对象的类类型，因为客户端可以创建任何新类并将其对象发送到我的服务。我也使用了ElasticTableEntity但它没有用。当我尝试为服务调用HTTP POST方法时，它会抛出System.InvalidOperationException类型的异常，说不能返回Int32类型属性的二进制类型。可能是序列化问题。

我尝试过以下代码：

public class MyCustomEntity
{
    [PartitionKey]
    public string Partition { get; set; }

    [RowKey]
    public string Row { get; set; }

    public int Age { get; set; }

    public string Name { get; set; }

    public string CustomName { get; set; }
}

static void Main(string[] args)
{            
    var customObject = new MyCustomEntity
    {
        Partition = "MyTestEntity",
        Row = "1",
        Age = 36,
        Name = "Name1",
        CustomName = "CustomName1"
    };

    dynamic elasticEntity = new ElasticTableEntity();
    elasticEntity.PartitionKey = "Partition123";
    elasticEntity.RowKey = (DateTime.MaxValue.Ticks - DateTime.Now.Ticks).ToString();
    elasticEntity.Name = "Pascal";
    elasticEntity.Number = 34;
    elasticEntity.Bool = false;
    elasticEntity.Date = new DateTime(1912, 3, 4);
    elasticEntity.TokenId = Guid.NewGuid();
    elasticEntity["LastName"] = "Laurin";

    Save(customObject);
    SaveElastic(elasticEntity);
}

public static T Save<T>(T entity) where T : class,new()
{
    WindowsAzure.Table.EntityConverters.TableEntityConverter<T> entityConverter =
        new WindowsAzure.Table.EntityConverters.TableEntityConverter<T>();

    ITableEntity dynamicEntity = entityConverter.GetEntity(entity);

    SaveRequest request = new SaveRequest { Entity = dynamicEntity };

    var client = new JsonServiceClient(<ServiceURL>);        

    var response = client.Post(request);

    return (T)response.Entity;
}

public static ElasticTableEntity SaveElastic(ElasticTableEntity entity)
{
    SaveElasticRequest request = new SaveElasticRequest { Entity = entity };

    var client = new JsonServiceClient(<ServiceURL>);

    var response = client.Post(request);

    return response.Entity;
}

有谁可以告诉我在这里缺少什么？

Answer 1

DynamicTableEntity和任何其他ExpandoObject默认情况下不会使用servicestack.text.jsonserializer或任何其他序列化程序进行序列化。您必须添加自定义序列化来处理这些动态对象。

带动态或DynamicTableEntity对象的ServiceStack发布请求
