如何在不使用临时文件的情况下将.NET对象序列化为Azure Blob存储？

Question

I want to store a .NET object into Azure Blob Storage.

Currently I serialize it into an XML file using TextWriter ( episodeList is the object I want serialized):

XmlAttributeOverrides overrides = new XmlAttributeOverrides();
XmlAttributes Xmlattr = new XmlAttributes();
Xmlattr.XmlRoot = new XmlRootAttribute("EPISODES");
overrides.Add(typeof(List<EpisodeData>), Xmlattr);
XmlSerializer serializer = new XmlSerializer(typeof(List<EpisodeData>), overrides);
TextWriter textWriter = new StreamWriter(@"C:\movie.xml");
serializer.Serialize(textWriter, episodeList);
textWriter.Close();

and then upload the file into Blob Storage:

CloudBlobClient blobStorage = createOrGetReferenceOfBlobStorage(folderName);
string uniqueBlobName = string.Format("{0}/{1}", folderName, fileName);
CloudBlockBlob blob = clouBblockBlobPropertySetting(blobStorage, uniqueBlobName, ".txt");
using (StreamWriter writer = new StreamWriter(blob.OpenWrite()))
{
    writer.Write(content);
} 

Is it possible to somehow skip the temporary file so that the XML is directly uploaded into Azure Blob Storage?

You could do the following. Create a MemoryStream instance and use XmlSerializer.Serialize(Stream stream) to serialize the object into the memory stream, then "rewind" the stream to beginning using Seek() . Then you call CloudBlob.UploadFromStream() to upload the stream contents to the blob.
