How to get the name of client machine inside OperationContext Object?

How to get the name of client machine inside OperationContext Object?

  Hello Jdang,

  The NetTcpBinding wraps a TCP socket as a channel and sockets don't have any built-in feature for for providing the sender's machine-name. In other words, it isn't povided by the underlying transport so we don't have a way to surface it to you.

  Do you have the option of modifying your contract so it includes the client's machine-name as one of the parameters Alternately, you could add a message-inspector that adds the machine-name as a custom header that you then extract in your service.

  Regards,
  David

  The From header isn't always sent. What binding are you using What does your contract look like

  Also, keep in mind that the orginal sender of a message can't always be determined. WIth transports like MSMQ, I can determine who sent the message (signature, other properties), but I can't determine what machine the user sent things from. It is also possible to fill in the From header with bogus data.

  David,

  Thanks for your time. Yes, I have to use MessageInspector to do this by adding my custom object into MessageHeaders collection to carry my extra data from client to the server. A little work without any book or documentation but it works now.

  JDang
