Can we use PLC programming by the language C#?

ok i will answer you using my way , if you are going to use PLC to control a machine so its more easy to use it , but if you are going to use the c# to make a software so it more easy to you .
dear mohammad tell us what u are looking for and make your question more clear and i will try to find for the best answer tx.

why u want use it? and how?

you can use mikroC its similar to C lang

I think Not possible

Yes, you can use C compiler or C lang. to programming PLC

PLC usually use hexadeciml languag ... and u can use programm that is name (micro c) to write any pro for PLC after that ,this pro (micro c) well convert your c pro to any taps of language that use for your PLC

Basm Allah Alrahman Alrahim 

 

PLC , I remember is just a processor or a micro-controller inside package , and to deal with it you must learn special language made for PLC from different vendors , one of those vendors I remember was Siemens and I think Mitsubishi made PLC either , If you want more general learning learn how to make programs for any micro-controller by C or C++ or other languages like java , but C and C++ are stronger or the best

 Thank you for this question that help us to search and learn

you may mean you want to code to your machine if So ... you could use a software coding against PLC device called ( Trysim ) it's a German Technology and have a German version and English so

if you want take a look :Trysim.de

a PDF tutorial for the program : http://www.trysim.de/en/downloads/TrySim.pdf

if you want to download a Copy for testing : Trysim Lite Version Download

Hope this help ..Regards

No. because as we should know that only we can design plc software in five language ie IL, LD, FBD, STL,CFC in large scale industries.

No according to the  IEC61131 standard we use only standard language for programming of PLC.
