Sockettype enumeration -- specifies the socket type represented by an instance of the socket class

Member name	Description
Dgram Supported by the. NET Framework Lite version.	Supports datagram, that is, the maximum length of a fixed (usually very small) connectionless and unreliable message. Messages may be lost or duplicated and may not be arranged in order when they arrive.DgramA Socket type does not require any connection before sending or receiving data, and can communicate with multiple hosts.DgramUse the datagram protocol (Udp) and InterNetwork AddressFamily.
Raw Supported by the. NET Framework Lite version.	Supports access to the basic transmission protocol. UseSocketType RawYou can use the Internet message Control Protocol (Icmp) and Internet Group Management Protocol (Igmp) for communication. At the time of sending, your application must provide the complete IP header. The IP header and option of the received datagram remain unchanged when it is returned.
Rdm Supported by the. NET Framework Lite version.	Supports messages that are connectionless, message-oriented, and reliably sent, and retains the message boundary in the data. RDM (messages sent in a reliable manner) messages are not duplicated when they arrive and are arranged in order. In addition, if the message is lost, the sender will be notified. If you useRdmInitializationSocketYou do not need to establish a remote host connection before sending and receiving data. ExploitationRdmYou can communicate with multiple hosts.
Seqpacket Supported by the. NET Framework Lite version.	The Network provides connection-oriented and reliable bidirectional transmission of sorted byte streams.SeqpacketIt does not repeat data and retains the boundary in the data stream.SeqpacketTypeSocketCommunicates with a single host and requires remote host connection before the communication starts.
Stream Supported by the. NET Framework Lite version.	Supports reliable, bidirectional, and connection-based byte streams without repeating data or retaining boundaries. This typeSocketCommunicates with a single host and requires remote host connection before the communication starts.StreamUse the Transport Control Protocol (Tcp) ProtocolType andInterNetworkAddressFamily.
Unknown Supported by the. NET Framework Lite version.	Specify unknownSocketType.

 

Note:SocketTypeSometimes it is implicitly indicated inAddressFamilyUsed inProtocolType. For example, whenSocketTypeIsDgram,ProtocolTypeAlways Udp. WhenSocketTypeIsStream,ProtocolTypeAlways Tcp. If you try to create an incompatible combinationSocket, ThenSocketWill cause SocketException.
