Quick Question

[Mike]

Hi,

I am using an enum to map to certain columns instead of using the string
name. When I use the enum as the indexer in a datarow it forces me to cast
it into an int. Shouldn't this be automatic at design time? See code
below:

private enum DataIndexer
{
OrderID,
SerialNumber
};

orderID = (string)currentRow[(int)DataIndexer.OrderID];
serialNumber = (string)currentRow[(int)DataIndexer.SerialNumber];

Why not this:

rderID = (string)currentRow[DataIndexer.OrderID];
serialNumber = (string)currentRow[DataIndexer.SerialNumber];

Thanks

The C# language spec states that an explicit cast is required to convert
between an enum type and an integral type.
