I have IEnumerable which contains number Data inside it.

Edit The IEnumerable is from System.Collection.Ienumerable directive.

Attached the snapShot of Viual Studio, Enum that Contains Data:

Just to brief about the above image, eLevelData is the IEnumerable variable, in which I have my data .

Now I want to go to the data at index 4 or 5, but I don't want to use foreach loop. Any suggestions please.

Thanks,

Subhen

var item = eLevelData.ElementAt(index);

If your collection is typed as IEnumerable instead of IEnumerable<T> you'll need to use the Cast extension method before you can call ElementAt e.g.

var item = eLevelData.Cast<RMSRequestProcessor.RMSMedia>().ElementAt(index)
