C # winform calls the EXE file in other languages and obtains the return value

Normally, winform cannot obtain the returned value of exe. In this case, I use the method to write the value in EXE to the CSV file, and then winform reads the CSV file.

 

Private void btngoodsselect_click (Object sender, eventargs E)
{
Parameterizedthreadstart PTS = new parameterizedthreadstart (runcommand );
Thread firstchildthread = new thread (PTS );
Firstchildthread. start ("apsi.exe h111601010102i. PSP + Arg-B "+ basescode +"-G "+ txtgoods. text. tostring () + "-s" + goodssegment + "");
}
