How do you get a list of all ModelState error messages? I found this code to get all the keys: ( http://stackoverflow.com/questions/888521/returning-a-list-of-keys-with-modelstate-errors)

var errorKeys = (from item in ModelState
        where item.Value.Errors.Any() 
        select item.Key).ToList();

But how would I get the error messages as a IList or IQueryable?

I could go:

foreach (var key in errorKeys)
{
    string msg = ModelState[error].Errors[0].ErrorMessage;
    errorList.Add(msg);
}

But thats doing it manually - surely there is a way to do it using LINQ? The .ErrorMessage property is so far down the chain that I don't know how to write the LINQ...
