例外

例

次のコード例では、セグメント内のデータをインターネット リソースに送信できるように、SendChunked プロパティを true に設定します。

注釈

SendChunked が trueされると、要求はセグメント内のインターネット リソースにデータを送信します。 インターネット リソースは、チャンクされたデータの受信をサポートする必要があります。

GetRequestStream、BeginGetRequestStream、GetResponse、または BeginGetResponse メソッドを呼び出して、要求の開始後に SendChunked プロパティを変更すると、InvalidOperationExceptionがスローされます。
