My generic method needs to serialize the object passed to it, however just insisting that it implements ISerializable doesn't seem to work. For example, I have a struct returned from a web service (marked with SerializableAttribute) that serializes to xml just fine, but, as expected, the C# compiler complains.
Is there a way I can check the object is serializable before attempting to serialize it, or, better still, a way of using the where
keyword to check the object is suitable?
Here's my full method:
public static void Push<T>(string url, T message)
where T : ISerializable
{
string xml = SerializeMessage(message);
// Send the message to Amazon SQS
SendMessageRequest sendReq = new SendMessageRequest { QueueUrl = url, MessageBody = xml };
AmazonSQSClient client = new AmazonSQSClient(S3User, S3Pass);
client.SendMessage(sendReq);
}
And SerializeMessage:
private static string SerializeMessage<T>(T message)
{
XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
using (StringWriter stringWriter = new StringWriter())
{
xmlSerializer.Serialize(stringWriter, message);
return stringWriter.ToString();
}
}
If this isn't possible, what's the best way to perform a check that an object is serializable at runtime?
