how to change fortran input to C#

[ayahamdy]

Dear Sir,
i have library written in Fortran it's input from C library using commands and it's run under windows using cygwin & i want to use this library as dll in my C# code and pass my input instead of c library .... idon't know if i can use GUI instead of this commands or No way ???

I dont fully understand your question...

You have a C# GUI and you want to pass data to a Fortran DLL? This is possible, only strings and arrays need a little bit more work. Search this forum, there a enough questions and sample code about this. A C# command line application + Fortran DLL should work too.

Hi
I tried to mix C# and Fortran too.
But it is not easy or almost impossible, because C# is running only in .NET enviroment and IVF not
so mixing these too seems not to be possible as easy as C++ & IVF.

Klaus,

everything depends on what you mean by mixing. You can't do it as in CVF, that's true. For .Net you need to "close your Fortran in dll" and use System.Runtime.InteropServices, then DLLImport where you specify/change default calling convention (C for IVF is default). MS calls it "consuming unmanaged code clients".

yes
this is what I mean when I say mixing.
Having one projekt and using C# for GUI or other things and Fortran for the number crunshing stuff.
We are not able to use IVF DLL or library in a C# Project.
I dont know why.

Klaus,

it's strange. What errors do you get? You should be able to do (almost) without a problem. You need System.Runtime.InteropServices. Take a look at this for examples how to call and pass data.

OK thanks
I will try again
