process from VB.Net to C with output read in the VB Net

From a VB Net program I lauch an executable in C with input arguments, by the Process structure.

So far the C prog writes 2 results (double variables) in a file that the VB prog opens and reads, and that works.

 

I wonder how to get the results directly in the VB prog, without using a file, as outputs of the C prog, through the Process. I hope that would enhance performance since there are many iterations.

 

Thanks

 

Best regards
