Refactoring XmlTextWriter, paranoid question

See more:

C#

I'm refactoring the following code:

using (StreamReader stream = new StreamReader(InputFilePath))
{
    XmlTextReader xmlIn = new XmlTextReader(stream);
    while (xmlIn.Read())
    {
        //Do stuff
    }
    xmlIn.Close();
}

First I'm, being a bit paranoid and want to check if the following will behave, as I'm unsure why this wasn't done in the originally:

using (XmlTextReader xmlIn = new XmlTextReader(new StreamReader(inputFilePath)))
{
    while (xmlIn.Read())
    {
        //Do stuff
    }
}

Secondly, I also vauguely remember there is a neater way than the new XmlTextReader(new StreamReader(inputFilePath))
instantiation, if I'm right suggestions would be useful.

Thanks.
