有人可以教我如何在C#中按字母顺序将项目插入列表中？
所以每当我添加到列表中,我想添加一个项目,这个列表在理论上可能变得相当大.
示例代码：
Public Class Person
{
public string Name { get; set; }
public string Age { get; set; }
}
Public Class Storage
{
private List<Person> people;
public Storage
{
people = new List<Person>();
}
public void addToList(person Person)
{
int insertIndex = movies.findindex(
delegate(Movie movie)
{
return //Stuck here,or Completely off Track.
}
people.insert(insertIndex,newPerson);
}
}
解决方法
定义一个比较器实现
IComparer<T> Interface：
public class PersonComparer : IComparer<Person>
{
public int Compare(Person x,Person y)
{
return x.Name.CompareTo(y.Name);
}
}
然后使用SortedSet<T> Class：
SortedSet<Person> list = new SortedSet<Person>(new PersonComparer());
list.Add(new Person { Name = "aby",Age = "1" });
list.Add(new Person { Name = "aab",Age = "2" });
foreach (Person p in list)
Console.WriteLine(p.Name);
如果仅限于我们的.NetFramework3.5,您可以使用SortedList<TKey,TValue> Class：
SortedList<string,Person> list =
new SortedList<string,Person> (StringComparer.CurrentCulture);
Person person = new Person { Name = "aby",Age = "1" };
list.Add(person.Name,person);
person = new Person { Name = "aab",Age = "2" };
list.Add(person.Name,person);
foreach (Person p in list.Values)
Console.WriteLine(p.Name);
仔细阅读MSDN artcile中的备注部分,比较此类和SortedDictionary<TKey,TValue> Class
