How to add an Item to a IEnumerable

Question

_{Sunday, March 7, 2010 7:15 AM}

Okay, I have this IEnumerable veriable named GradeProfiles

some where part of my code, I want to add an Item to the IEnumrable.. How can I possibly add another Item of the same type of that IEnumerable to GradeProfiles?

IEnumerable<XElement> GradeProfile;

//somewhere part of my program, add the items in GradeProfile, like GradeProfile.add(), or is there such thing?

Sorry, but I have to say that IEnumerables are only for enumerating. you can't add item to them directly and you should add the item to it's underlying source instead.My Blog - MSDN Complement by providing Visual C# Walkthroughs and Sample Codes - Founded In February 24, 2010

What you are looking for is concat 

IEnumerable<string> stringcol = new IEnumerable<string>();
stringcol = stringcol.Concat(new[] { "foo" });

Try that.
