Downcasting Objects

[TazzMann]

Hello All!
I have two objects, one that is read only and one that is read-write. I am trying to morph from Readonly to Readwrite. Below is the code I am currently using to morph:

private void btnCreate_Click(object sender, System.EventArgs e) 
		{
			try
			{
				m_roAddress = null;
				m_roAddress = new RSMedical.System.rwAddress();
			}
			catch (System.Exception ex)
			{
				System.Console.WriteLine(ex.ToString());
			}
		}

However when stepping through the code, when it gets to the line

m_roAddress = new RSMedical.System.rwAddress();

I get an exception stating that it is an invalid cast. What am I doing wrong?

Thanks in advance for the help!

What is the type of m_roAddress ?
I think if you declare somewhere:

object m_roAddress =null;

then the object assignment must work unless there are not other errors.
Having m_roAddress as object type, then you can cast it to other allowed/implemented casts.
