在Silverlight中向WCF添加压缩的最简单方法是什么？

[ServiceContract]
public interface IMyService
{
    [OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    Stream GetCompressedData();
}

public class MyService : IMyService
{
    public Stream GetCompressedData()
    {
        // 将数据序列化为JSON格式
        string jsonData = JsonConvert.SerializeObject(data);

        // 使用Gzip压缩
        byte[] compressedData = Compress(jsonData);

        // 返回压缩后的数据
        WebOperationContext.Current.OutgoingResponse.ContentType = "application/json";
        WebOperationContext.Current.OutgoingResponse.Headers.Add("Content-Encoding", "gzip");
        return new MemoryStream(compressedData);
    }

    private byte[] Compress(string data)
    {
        byte[] buffer = Encoding.UTF8.GetBytes(data);
        MemoryStream memoryStream = new MemoryStream();
        using (GZipStream gzipStream = new GZipStream(memoryStream, CompressionMode.Compress, true))
        {
            gzipStream.Write(buffer, 0, buffer.Length);
        }
        return memoryStream.ToArray();
    }
}

private void GetData()
{
    WebClient webClient = new WebClient();
    webClient.OpenReadCompleted += (sender, e) =>
    {
        using (GZipStream gzipStream = new GZipStream(e.Result, CompressionMode.Decompress))
        {
            using (StreamReader streamReader = new StreamReader(gzipStream))
            {
                string jsonData = streamReader.ReadToEnd();
                // 反序列化JSON数据并处理
            }
        }
    };
    webClient.OpenReadAsync(new Uri("http://localhost:8000/MyService/GetCompressedData"));
}
