Question

我学习WCF。我有WCF服务和WCF客户端。我的服务获取一个文件，然后对其进行编辑并将其返回。它仍然没有任何问题。我将一个文件传递给服务并通过通常的字节数组返回：

/// <summary>
/// DWG file resaving.
/// </summary>
/// <param name="source">The byte array of the source DWG file.</param>
/// <param name="dwgVersion">DWG file target version (enum).</param>
/// <returns>The result (the byte array) of DWG file resaving.</returns>
[OperationContract]
byte[] SaveAs(byte[] source, DwgVersion dwgVersion);

通过通常的字节数组将文件传递给服务（并将其恢复）是否是可接受的做法，或者在这种情况下使用其他容器来传递文件会更好吗？

或者更像是这样：

[ServiceContract]
public interface ITransferService
{
[OperationContract]
RemoteFileInfo DownloadFile(DownloadRequest request);

[OperationContract]
void UploadFile(RemoteFileInfo request); 
}

[MessageContract]
public class DownloadRequest
{
[MessageBodyMember]
public string FileName;
}

[MessageContract]
public class RemoteFileInfo : IDisposable
{
[MessageHeader(MustUnderstand = true)]
public string FileName;

[MessageHeader(MustUnderstand = true)]
public long Length;

[MessageBodyMember(Order = 1)]
public System.IO.Stream FileByteStream;

public void Dispose()
{ 
    if (FileByteStream != null)
    {
        FileByteStream.Close();
        FileByteStream = null;
    }
}   
}

通过通常的字节数组将文件传递给服务（并将其恢复）是否是可接受的做法？
