TcpClient.ConnectAsync 메서드 (String, Int32)
게시 날짜: 2016년 11월
어셈블리: System(System.dll에 있음)
[HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)] public Task ConnectAsync( string host, int port )
This operation will not block. The returned Returns T:System.Threading.Tasks.Task object will complete after the TCP connection has been established. This method does not block the calling thread while the connection request is underway.
Call this method to establish a synchronous remote host connection to the specified host name and port number as an asynchronous operation. After connecting with the remote host, use the M:System.Net.Sockets.TcpClient.GetStream method to obtain the underlying T:System.Net.Sockets.NetworkStream. Use this T:System.Net.Sockets.NetworkStream to send and receive data.
If IPv6 is enabled and the M:System.Net.Sockets.TcpClient.ConnectAsync(System.String,System.Int32) method is called to connect to a host that resolves to both IPv6 and IPv4 addresses, the connection to the IPv6 address will be attempted first before the IPv4 address. This may have the effect of delaying the time to establish the connection if the host is not listening on the IPv6 address.
If you receive a T:System.Net.Sockets.SocketException, use P:System.Net.Sockets.SocketException.ErrorCode to obtain the specific error code. After you have obtained this code, you can refer to the Windows Sockets version 2 API error code documentation in MSDN for a detailed description of the error.
This member outputs trace information when you enable network tracing in your application. For more information, see [<topic://conUsingNetworkTracing>].
