reding array returned from COM object call

[IonelBurtan]

Hi there,

How can COM object and a COM object wrraper dll generated with tlbimp. I use the generated dll in one simple C# test project, adding it to references.

the following piece of code:
...
MyComObjectClass cs = new MyComObjectClass();
object objReturned = cs.MyComMethod(param1, param2);


Now, in objReturned I have a 2 dimensional SAFEARRAY (packed as variant of course). The COM call works fine, I checked, but how can I read the result in C#.
I tried with Array class but this requires me to know the array dimensions beforehand(which I don't) and I cannot make a coresponding cast.

thanks,

I will assume that the array contains integers :

foreach( object anArr in ( objReturned as System.Array))
{
foreach( object anInt in ( anArr as System.Array))
{
int iAVariable = (int) anInt;
//reconstruct the bi-dimensional array or do what you like with the values
}
}

I didn't test the code but I hope you've got the basic ideea. It worked for me for one-dimensional arrays (the inner foreach) and this should probably work for bi-dimensional arrays too.

The problem is that the array is a variant array.
It does not hold elements of the same type.

I solved the problem by casting to a object[,]

Thanks for ideea
