C# 如何获取AllJoyn byte[]属性

我有一个像这样的AllJoyn酒店

<property name="DeviceAddresses" type="ay" access="read">

属性值通过以下方式创建：

object o = Windows.Foundation.PropertyValue.CreateUInt8Array(value);

但是我找不到方法（强制转换或其他方式）将字节取出。

我用来访问AllJoyn方法。它使用

IAsyncOperation<InvokeMethodResult> InvokeAsync(IList<object> @params);

编辑：如果不想自己编程，可以使用。目前还不确定是否支持字节数组

IAsyncOperation<InvokeMethodResult> InvokeAsync(IList<object> @params);

InvokeMethodResult result = await MyAllJoynMethod.InvokeAsync(new List<object> { "parameter", 2 });
if (result.Status.IsSuccess)
{
    var resultList = result.Values as IList<object>;
    foreach (var resultListItem in resultList)
    {
        var pairs = resultListItem as IList<KeyValuePair<object, object>>;
        foreach (var pair in pairs)
        {
            var key = pair.Key as string; //<- type string taken from MyAllJoynMethod definition
            var variant = pair.Value as AllJoynMessageArgVariant;//<- type AllJoynMessageArgVariant taken from MyAllJoynMethod definition (variant)

            if (variant.TypeDefinition.Type == TypeId.Uint8Array)
            {
                var array8 = j as IList<object>;
                foreach (byte b in array8)
                {
                    // do something with b
                }
            }
        }
    }
}
