How does one tell if an IDisposable object reference is disposed?

Is there a method to check if object has been disposed different then

try
{
    myObj.CallRandomMethod();
} catch (ObjectDisposedException e)
{
    // now I know object has been disposed
}

In my case I'm using TcpClient class that has Close() method which disposes object and this can happen in piece of code I don't have control of. In this case I would like to have better solution then catching exception.
