How can I convert the collection object to an int?

Question

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

shimtanny · Answer

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

gemtraveller · Answer

Yes, locations is the collection.

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

gemtraveller · Answer

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

gemtraveller · Answer

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

gemtraveller · Answer

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;

shimtanny · Answer

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
