Communication state defines the states in which a communication-oriented object can exist.
These states are defined as enumerations in the System.ServiceModel.dll.
http://msdn.microsoft.com/en-us/library/system.servicemodel.communicationstate(v=vs.110).aspx defines the various names in the enumeration however we do not get to see the enumeration values.
As the above link explains there are four main states that a communication-oriented object can exist. They are:
- Created
- Opened
- Closed
- Faulted
The transitory states of the communication-oriented object are:
- Opening
- Closing
The various state diagrams are shown below.

The enumeration is actually defined as:
public enum CommunicationState
{
Created,
Opening,
Opened,
Closing,
Closed,
Faulted
}
So Created = 0, Opening = 1 and so forth.
