I am having trouble figuring out how to call a c# program and pass it an array of floating point values from Fortran. I have a fortran subroutine, which is being called from various other fortran subroutines and it needs to pass an array of floats onto a C# function that it will be calling. So far I have only been able to pass arrays to the C# function if I use the object declaration method to declare a new .NET array and then pass that as the function parameters. While I could go back and rewrite all of the fortran code to explicitly use .NET arrays, I would like to avoid that.

As and example of what I am trying to do:

SUBROUTINE fortranfunc (y)
ASSEMBLY_EXTERNAL(NAME="CS_Test.Functions.test") :: TEST
REAL(SP), DIMENSION(, INTENT(IN) :: y

call TEST(y)
.
.
.
END SUBROUTINE

namespace CS_TEST {
public class Functions {
public static void test(ref float[] y) {
.
.
.
}
}
}

And when I try to compile I get the error message: "No .NET method matches this call" on the call TEST(y) line

I am probably missing something simple here, but I have not been able to find it in the documentation.

One way to proceed is to use

public static unsafe void test(float* y)

and to set the C# project proterties to accept unsafe code
