Read and write from a serial port using c#

[Daniel Åberg]

I can't find how I can, in c#, open a serial port and
read and write to it. Anyone that knows if there is any
namespace with methods or code example.

[Darcy Ryan]

I don't believe there is any direct framework support for
this, so you are stuck using a third-party library (check
for serial classes on a site like codeguru.com) or
interfacing directly using Windows API calls (Createfile,
Readfile, Writefile, etc).

Thanks for a quick reply. I still hope framework has
support for it because I realy need it. Anyone else that
are sure framework support it or not.

Here is a link to an MSDN Mag article that discusses some
techniques to access the serial port. Unfortunately it
seems to confirm the lack of direct support in the
framework.

A search in Google will also yield a lot of commercially
available classes if you are developing this for a
business need.

There's a sample class that works with COM interop to achive the serial port
functionality on gotdotnet.com [1]

Hello Daniel,

Thanks for posting in the group.

Darcy and Patrik are right. There is no direct framework class to develop
serial port application. We need to use PInvoke to call Win32 APIs to
achieve it. Some developers even wrapper all the related APIs in a .NET
class library, just as what Patrik posted. You could refer to it for code
samples.

By the way, if you don't want to expose your real email address in the
group to avoid spam virus email, you could register a no spam alias at:
http://support.microsoft.com/default...sdn/nospam.asp
&SD=msdn.

Does that answer your question?

Thanks a lot. I have now a couple of suggestions that I
will start to test.
