c# com call

I am able to instantiate and make calls to a com module
that use only primitive data types, but I simply don't
know what the c# equivalent is for a function expecting
short*. Any help would be appreciated.
 
Hi,

Did you call this function as "DllImport" static function?
If so then you can try e.g.:

[DllImport(...)]
public extern static void MyImportedMethod(ref short myShort, ...);

But i can not guarantee it will work...

Regards

Marcin
 
I tried this, which compiles cleanly, but my app hangs
when I try to run it:

short[] array = new short[16];

foreach ( int i in array )
{
array = 0;
}

fixed (short* dest = array)
{
myobj.SomeFunction(19, 1, ref *dest);
}
 
There is no equivalent in C#. You can get around this by using unmanaged
code and having a point to a System.Int.32...
Or you could change the params in your COM to a short (then you could just
pass in a System.Int.32 w/o using unmanaged code).
This would be more of a "how do I make calls to managed/unmanaged code from
unmanaged/managed code?" question.

Regards,

Eric
