I want to deserialize a file. In one ofe my classes I have an array
like:
public class MyClass
{
public MyArray[] theArray;
}
i.e. an arry of an own defined class. While reading the file I only know
the dimension on the end of reading, so I keep the array elements in an
ArrayList "records". At the end I "only" have to assign the ArrayList to
the Array-field "theArray". And there is my problem.
arrayField.Fiel dType shows "MyArray[]", this is correct for me. If I try
with
arrayField.SetV alue(records.To Array(), instanceOfMyCla ss);
to assign the Array I get the error message that the objecttype can't be
converted to the destination type.
That's right, the object type is "object[]" and the destination type is
"MyArray[]".
How can I do the typecast at runtime?
Or is there another way to do this?

Hi Wernfried,
Before digging more deeply into this.
Are you sure that the invalid cast is because of the arrays arrayField.SetV alue(records.To Array(), instanceOfMyCla ss);
AFIK in FiledInfo.SetVa lue first comes the object which field you set and
then the value of the field. So I believe you should switch the paramers
arrayField.SetV alue(instanceOf MyClass, records.ToArray ());
Try that and tell if the probles is still there

Thanks. This was the problem. I certainly got confused with my variabale
names and missed the order.

This is what I'm trying to do:
I wish to build a function that crawls any COM object (interop). I did
