Very basic meter reading sample code with TCP in C#

Hello. i am trying to write a code to connect and read data from a meter using tcp/ip in C#(VS2017).

I get the sample codes from official site. I downloaded the nugets.
However there are undefined variables, some terms unkown by .dll's. I could not clean the errors

Is there any simplest, shortest sample codes for doing basic job, please?

Hi,

Have a look at this page, hope this helps: http://www.gurux.fi/Gurux.DLMS.Client

Thanks but that's the page I

Thanks but that's the page I already got the codes from, in which i could not clear errors.

That's why i requested another example. maybe a shorter one only for tcp/ip communication.

Hi,

Have you installed gurux.net, gurux.dlms or any other packages that is needed from Nuget?

Hi,

Hi,
Of course i installed the packages. And at the beginning of the solution i am using:
Gurux, Gurux.DLMS, Gurux.DLMS.Objects, Gurux.Common, Gurux.Net, GXDLMS and more...

Hi,

DLMS is not a simple protocol and you need all those files to make a connection for your meter.
It's good to know that you have installed those references from Nuget. That is common error.

What kind of errors you are getting? Please, don't post a picture.

- Different from client which is already defined, there's a "Client" which is not defined but used.
- Client, WriteTrace, Media, WaitTime does not exist in the context
- InterfaceType does not contain a definition for 'Wrapper'
- Method group is not a reference type as required by the lock statement.
- Cannot implicitly convert type 'void' to 'Gurux.DLMS.GXReplyData' --> for --> reply = ReadDLMSPacket(it, reply);
- 'GXDLMSClient' does not contain a definition for 'GetObjects' and no accessible extension method 'GetObjects' accepting a first argument of type 'GXDLMSClient' could be found (are you missing a using directive or an assembly reference?
