I have a strange compile error. C2664 cannot convert parameter 2 from int to
int...

Earlier in my code I was setting up my dataset...

I add an int field like so...

Books->Columns->Add("Volume",System::Type::GetType(S"System.Int32"));

Then below I try to add an int value to it.

Nr->Item[S"Volume"] = Volume;

(Nr is a new Datarow of the table "books"

And get this error:

error C2664: 'void System::Data::DataRow::set_Item(int,System::Object __gc
*)' : cannot convert parameter 2 from 'int' to 'int'

I checked to see if it was because the column and the variable have the same
name but setting it to the value 1 also caused the same error.

What am I doing wrong?
 
Gary,

A simpler way is:
Books->Columns->Add("Volume", __typeof(int));

Then below I try to add an int value to it.

Nr->Item[S"Volume"] = Volume;

The problem here is that the compiler gets confused because of overloads of
the Item property. A simple way to get what you want is to simply box the
volume:

Nr->Item[S"Volume"] = __box(Volume);
