在MyClass中添加通用列表，但如何？
我如何在通用类中添加列表？ 首先我的通用类是：
[Serializable]
public class ScheduleSelectedItems
{
private string Frequency;
List FrequencyDays = new List();
private string Time;
private string StartTime;
private string EndTime;
private string StartDate;
private string EndDate;
private string Name;
public ScheduleSelectedItems(string frequency,List frequencydays,
string time, string starttime,
string endtime, string startdate,
string enddate, string name)
{
Frequency = frequency;
FrequencyDays = frequencydays;
Time = time;
StartTime = starttime;
EndTime = endtime;
StartDate = startdate;
EndDate = enddate;
Name = name;
}
}
[Serializable]
public class ScheduleSelectedItemsList
{
public List Items;
public ScheduleSelectedItemsList()
{
Items = new List();
}
}
and i want to add ScheduleSelectedItems into ScheduleSelectedItemsList in form1.cs
Form1.cs codes is here :
private void timer1_Tick(object sender, EventArgs e)
{
string saat = DateTime.Now.ToShortTimeString();
string bugun = DateTime.Today.ToShortDateString();
ScheduleMng smgr = new ScheduleMng();
ScheduleItemsList schlist = smgr.LoadXml();
List list = new List();
for (int i = 0; i = Convert.ToDateTime(schlist.Items[i].StartDate.ToString())
&& Convert.ToDateTime(bugun) slist.Items.Add（列表）; ---->我不使用这些代码。 这些错误“包含一些无效的论点”，你怎么能帮助我？ :)
我想这就是你想要的：
List<ScheduleSelectedItems> list = new List<ScheduleSelectedItems>();
泛型可以在函数/类的最后被简化
List<T> //generic type
T表示一个类型，即int （主类型）或MyClass （类）
所以
List<MyClass> listOfMyClass = new List<MyClass>();
是MyClass类型的项目List
在你的情况下，你没有得到一个泛型类，但我认为你可以通过以下方式使它泛型：
public class ScheduleSelectedItems<T>
{
private string frequency;
List<T> itemsToSchedule = new List<T>();
//(...)
public ScheduleSelectedItems(string frequency,List<T> items, /*(...)*/)
{
this.frequency = frequency;
this.itemsToSchedule = items;
//(...)
}
}
然后调用它
ScheduleSelectedItems<FrequencyDays> myItems = new ScheduleSelectedItems<FrequencyDays>("frequency", new List<FrequencyDays>())
它使用FrequencyDays列表创建您的课程的新对象
