这是我Dictionary
如何将类添加到Dictionary中的嵌套类?
public class Company
{
public string ComID { get; set; }
public string ComName { get; set; }
public List<Dep> Dep { get; set; }
}
public class Dep
{
public string DepID { get; set; }
public string DepName { get; set; }
public string isDepAt { get; set; }
public List<User> User { get; set; }
}
public class User
{
public string UserID { get; set; }
public string UserName { get; set; }
public string UserTitle { get; set; }
public string UserExt { get; set; }
public string UserIsAt { get; set; }
}
protected void Page_Load(object sender, EventArgs e)
{
Dictionary<int, Company> dic = new Dictionary<int, Company>();
DataTable data=new DataTable();
//get data ...
//Creat User
//Creat Dep and add User to class
//Creat Company and add Dep to class
//Add Company to Dictionary 'dic'
}
后数据绑定,我怎么会在Dictionary
添加新User
的内在张力结构?
我用这样的方式:
User _user = new User()
{
UserID = "123",
UserName = "John cena",
UserTitle = "Champian",
UserExt = "7777",
UserIsAt = "Yes"
};
dic.Where(x => x.Value.Dep.Select(y => y.DepID == "abcDep").FirstOrDefault()).FirstOrDefault().Value.Dep.Where(z => z.DepID == "abcDep").FirstOrDefault().User.Add(_user);
有更好的办法来做到这一点?
不知道你在寻找什么样的帮助。很明显,你期望的项目有时不会被发现(因为你正在使用'FirstOrDefault()'),但是如图所示的其他手形代码(大概简化/组合在一行中作为后期样本)并不处理项目不存在的情况。请确保提供包含'null'处理的完整代码,以便有人可以为您的实际代码提供合理的建议。 –
如果内部集合有频繁更新,为什么不能使用字典instread?比如'Dictionary' –
