Tôi lấy dữ liệu từ một dịch vụ WCF web và khi dữ liệu là hơn 0,2 triệu hồ sơ tôi nhận được một ngoại lệ mà là như dưới:System.ServiceModel.CommunicationException: Kết nối tiềm ẩn đã được đóng
System.ServiceModel.CommunicationException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. ---> System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

web của tôi .config trông giống như sau:
<basicHttpBinding>

Tôi chắc chắn rằng dịch vụ web của tôi đang truy xuất dữ liệu từ DB. nhưng không thể chuyển sang web của tôi từ nơi tôi bắt đầu cuộc gọi. Cảm ơn trước sự giúp đỡ nào.
Tăng thời gian chờ kết nối trong tệp cấu hình của bạn. – gleng
Tăng maxBufferSize, maxReceivedMessageSize trong các liên kết được đề cập trong Web.config –
