I'm not suggesting you actually do this, but you could use a single helper class to make this easy for all out parameters:

public static class OutHelper

    [ThreadStatic]
    public static T Ignored;
}

Then you can call:

if (DateTime.TryParse(text, out OutHelper.Ignored))

It's horrible, uses a public mutable field, and if your application is also executing with some malicious code, it gives that code access to the last value you've parsed... but it should work :)
