/// <summary>

private void ShowImages(MemoryStream msShowStream)
{
// 從緩衝區資料流清除所有內容輸出。
Response.ClearContent();
// 取得或設定輸出資料流的 HTTP MIME 類型。
Response.ContentType = "Image/Jpeg";
// 將二進位字元的字串寫入 HTTP 輸出資料流。
Response.BinaryWrite(msShowStream.ToArray());
// 將目前所有受緩衝的輸出傳送到用戶端、停止網頁的執行，並引發 EndRequest 事件。
Response.End();
}

直接用Response的方法寫字節流就不會出問題了
