So, I see this type of pattern in a bunch of different places in my code where I use arrays of objects contained in other objects.  Often, I want to use a System.Array object, like string [] instead of an ArrayList or other collection for the simplicity, ease of serialization, etc. But, I find myself re-writing code that looks like this do perform the simple task of adding an item on the end of the array:

[Serializable]
public class WatchListStatus
{
    private WatchListStatusItem [] m_statusItems;

    public void AddStatusItem(WatchListStatusItem item)
    {
        // Get the length
        int intLength = (this.m_statusItems == null) ? 0 : this.m_statusItems.Length;
        WatchListStatusItem [] tmpStatus = WatchListStatusItem[intLength + 1];

        // Copy items if needed
        if(intLength > 0) Array.Copy(this.m_statusItems, tmpStatus, intLength);

        // Add to the end of the array
        tmpStatus[intLength] = item;

        // set the private instance 
        this.m_statusItems = tmpStatus;
    }
}

So, here's my question for everyone... Is there a better way?  I know I could do something generalized with reflection, but I'm not sure that the payoff would be that great.  I guess I'm searching for a static method of the System.Array class that could append an object, but I'm not aware of one.
