How can I convert the collection object to an int?

gemtraveller

Here is my code object sO = locations.Find(e.Source); I want to convert the object to an int so I can manipulate the values extracted from the collection.

Aha, hmmm... Then maybe you should cast it to an ArrayList, then see what is inside the ArrayList. ArrayList al = (ArrayList) sO; foreach(object o in al) { Console.WriteLine(o); } Simon

The GetType says it's a Systems.Collections.ArrayList

Check type with Type t = sO.GetType(); It cannot be an int (otherwise the cast wouldn't fail), but what else? Simon

Yes, locations is the collection.

Aha, and what type is sO? Is this the collection? Simon

Also, Convert.ToInt32(sO); Additional information: Specified cast is not valid.

An unhandled exception of type 'System.InvalidCastException' occurred in SmartMap.exe Additional information: Specified cast is not valid. int sI = (int)sO;

Do you have casted the object? Respectivly have you tried Convert.ToInt32(...)? Simon

It's giving this error: Cannot implicitly convert type 'object' to 'int' I am using a Collection that is an ArrayList using the IList interface and trying to figure out how to Get the value's out of the collection. I don't want to use enumeration because I am manually putting in the Keys and don't just want to traverse through it sequentially.

Convert.ToInt32(sO); may also work with check in one row: int i= (sO is int)?(int)sO:0;

If sO is type Int32, than you can cast it down. int i = (int) sO; If necessairy, check first the type: int i; if (sO is int) { i = (int) sO; } Simon
