所以我是新的而不是c#,我没有想法尝试这个。我花了几个小时研究,但还没有找到解决方案。
我的问题是针对函数getUpcomingDates():
如何将变量 myDates
声明为与 getAllDates
方法返回?
我试过的方法之一是:MyDate[] myDates = new getAllDates();
但是我在getAllDates下面有一条红线说:'这是一种方法,但用作类型。'
这样做的正确方法是什么?
[WebMethod]
private MyDate[] getAllDates()
{
System.Collections.ArrayList myDates = new System.Collections.ArrayList();
MyDate thisDate;
thisDate = new MyDate(DateTime.Parse("9/1/2011"),
"Get classes ready", "Begin of fall semester");
myDates.Add(thisDate);
thisDate = new MyDate(DateTime.Parse("1/1/2011"),
"New Year", "Happy 2011!");
myDates.Add(thisDate);
thisDate = new MyDate(DateTime.Parse("12/16/2011"),
"BUS ADM 531 Final Exam", "See study guide on course Web pages");
myDates.Add(thisDate);
return (MyDate[])myDates.ToArray(typeof(MyDate));
}
[WebMethod]
private MyDate[] getUpcomingDates()
{
MyDate[] myDates = new getAllDates();
System.Collections.ArrayList upcomingDates = new System.Collections.ArrayList();
foreach (MyDate thisDate in myDates)
{
if (thisDate.CalendarDate > DateTime.Now)
{
//date is upcoming, add to output list of dates
upcomingDates.Add(thisDate);
}
else
{
//not an upcoming date, do not add to output list
}
return (MyDate[])upcomingDates.ToArray(typeof(MyDate));
答案 0 :(得分:5)
要调用某个函数,您只需要(从行中删除new
)
MyDate[] myDates = getAllDates();
