Hello,

I am writing a very simple function that always tell me the object is not instantiated. I don't understand what's the problem. Here are the code:

private bool HallarUsuario(string pUsuario)
{
    if ( Application["usuarios"].ToString() == null )
        return false;
    if ( Application["usuarios"].ToString().IndexOf(pUsuario) == -1 )
        return false;
    else
        return true;
}

-------------------------------
World only exists into your mind.

There is no "ToString()" method on "null" so this won't work:

    Application["usuarios"].ToString() == null

The application collection is not returning an object, so you need to check for just that:

if ( Application["usuarios"] == null )
