Hi,

How do I convert a byte[] to an object[]?

I am trying to use IADs PutEx and the last parameter required a variant
array.

Thanks,
Alex

I suspect what you need is:

byte[] barray;
PutEx(..., new object[] { barray });
 
Hi Ben,

Thanks for the suggestion.

What I did to make it work is:

object[] objArr = new object[1];
objArr[0] = barray;
PutEx(....,objArr);

As I am just learning C# so I am not so familar with your syntax. Is it
doing the same?

Thanks,
Alex

Hi Peter,

I did manage to convert byte[] to object[] using Arrays.Copy but it does not
solve me problem. Actually PutEx is expecting an object array containing
byte array. Doing that so my problem.

Thanks,
Alex

Copy each element to an object[]. I take as granted that you really have
to do this, 'cause it's not going to be efficient. :)

Hi Alex,

Thanks for your feedback.

Actually your code works the same way as what Ben provided. "new object[] {
barray }" means creating an object array with length determined by the
number of elements in {}. Since there is only one element "barray" in the
{}, the object array will have length "one". Also, in this one element
object array, the only element is a reference to the byte array. This is
the same logic as your code does

Thanks.

Yes, the compiler will expand

new T[] { t1, t2, ... tn }

into

T[] temp = new T[n];
temp[0] = t1;
temp[1] = t2;
temp[n-1] = tn;

and use temp in the original function call

Thanks,
Alex
