I've got this code... seems nice and elegant, but apparently the framework don't like it when i mess with a collection while iterating through it:
foreach (KitGroup kg in ProductToTransfer.KitGroups)
{
// Remove kit groups that have been excluded by the user
if (inKitGroupExclusions != null && inKitGroupExclusions.Contains(kg.KitGroupID))
ProductToTransfer.KitGroups.Remove(kg);
else
{
// Loop through the kit items and do other stuff
//...
}
}
The error it throws when it iterates to the 2nd object in the collection is: "EntitySet was modified during enumeration"
I know i could create a new collection of KitGroup objects (or even just IDs) that i want to remove, and then another loop afterwards to loop through these, and remove them from the collection, but this just seems like unnecessary extra code... can anybody suggest a more elegant way of achieving the same thing?
Cheers Greg
