ch5 p130 DateTime

Hi. Sorry for harping on about the same bit of code as others have.
In my version of the dateTime code I am getting an error "DateTime" is a namespace but is being used like a 'type' on the 2 lines that mention DateTime (in the code for the UpdateTimeInfo method).

Code:

private void UpdateTimeInfo()
    {
        int days;
        DateTime myTime = new DateTime();
        myTime = DateTime.Now;
        DateTime newYears = new DateTime(myTime.Year, 12, 31);

I have now downloaded the code from the Wrox site but still get this error. I am using 2010 express.
What am I doing wrong please?

look at the namespace that this code resides in; is it DateTime? if it is then the reason you are getting the erorrs is because the complier does not know what DateTime you are trying use so it makes a guess and gives you an error. To fix fully qualify the the DateTime you are trying to instanciate.

Code:

private void UpdateTimeInfo()
    {
        int days;
        System.DateTime myTime = new System.DateTime();
        myTime = System.DateTime.Now;
        DateTime newYears = new System.DateTime(myTime.Year, 12, 31);
}

Thanks for that. I understand your reply now. However in the book, scope does not seem to be dealt with until Part III.
I naively thought that because the code includes a reference to "using System" that this would have satisfied any reference to DateTime--obviously not!

Thanks again

Had this code resided in a namespace that was Datetime it would have been sufficient but since it did you have to fully qualify any names that are in any of the name spaces.
