Java代码修改为C#代码

[jiangxi43]

把下面的Java代码修改为C#代码
GregorianCalendar valGc = new GregorianCalendar(2008, 10, 21);
GregorianCalendar dateBeforeGc = new GregorianCalendar(2007, 10, 21);
if(valGc.getTime().equals(dateBeforeGc.getTime()))
{
System.out.println("Equals");
}
boolean b = valGc.before(dateBeforeGc);
System.out.println("before" + b);

DateTime valGc = new DateTime(2008, 10, 21);
DateTime dateBeforeGc = new DateTime(2007, 10, 21);
if (valGc.ToLongDateString().Equals(dateBeforeGc.ToLongDateString()))
{
Console.WriteLine("Equals");
}
int c = valGc.CompareTo(dateBeforeGc);

Console.WriteLine("before"+ (c<0));
