リモート マシンにある WCF サービス ホストから大きな zip ファイル (>200 MB) をダウンロードするダウンロード アプリケーションを作成しました。クライアントは、 "nettcprelaybinding"を使用して、azure サービス バス経由でこの WCF サービスと通信します。
zip ファイルをダウンロードするために、WCF サービスはストリームを作成して返します。クライアントでは、このストリームを使用して zip ファイルに書き込みます。
しかし、このストリームの読み取り中に、「ストリームの読み取り中に例外がスローされました」というIOExceptionが ランダムに取得されます。. 内部例外をよく見ると、SocketException (s)が並んでいます。
以下は、クライアントの WCF トレース ユーティリティからの XML スタック トレースです。

ストリームを読み取るためのコード:
int bufferSize = 4096;
byte[] buffer = new byte[bufferSize];
int bytesRead = streamInfo.FileByteStream.Read(buffer, 0, buffer.Length);
int totalBytesRead += bytesRead;
while (bytesRead > 0)
{
//WRITE BUFFER TO ZIP FILE
zipFileStream.Write(buffer, 0, bytesRead);
zipFileStream.Flush();
buffer = new byte[bufferSize];
//READ BYTES FROM SERVER STREAM
bytesRead = streamInfo.FileByteStream.Read(buffer, 0, buffer.Length);
totalBytesRead += bytesRead;
}
読み取りプロセスが終了した後、このストリームを最終ブロックに配置しています。

なぜこれが起こっているのか、私にはまったくわかりません。Service Bus のエラー、既知の問題、または Service Bus のタイムアウトが原因ですか? サービス バス クォータについては、次のリンクを参照しています: http://msdn.microsoft.com/library/ee732538.aspx
ここで何が間違っていますか？ストリームを読み取るために適切なバッファ サイズを設定する必要がありますか? またはmaxBufferSizeとmaxBufferPoolSizeを設定する必要がありますか?
maxBufferSizeとmaxBufferPoolSizeを 2147483647 に設定しようとしましたが、それは役に立ちません。
大きなファイルのストリーミングについては、次のリンクを参照しています: http://msdn.microsoft.com/en-us/library/ms733742.aspx
私は本当にうんざりしていて、なぜこのエラーが発生するのか理解できません。助けてください。
編集: 上記で私を助けることができない場合は、IOException が発生したときに同じ時点からストリーミングを再開する方法を教えてください。それは大いに役立つでしょう。どうもありがとう。
