如何在C#中创建SortedList对象的浅表副本？
要创建SortedList对象的浅表副本，代码如下-
示例
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args){
SortedList list = new SortedList();
list.Add("A", "Jacob");
list.Add("B", "Sam");
list.Add("C", "Tom");
list.Add("D", "John");
list.Add("E", "Tim");
list.Add("F", "Mark");
list.Add("G", "Gary");
list.Add("H", "Nathan");
list.Add("I", "Shaun");
list.Add("J", "David");
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in list){
Console.WriteLine(d.Key + " " + d.Value);
}
ICollection col1 = list.Values;
Console.WriteLine("\nValues...");
foreach(string s in col1)
Console.WriteLine(s);
ICollection col2 = list.Keys;
Console.WriteLine("\nKeys...");
foreach(string s in col2)
Console.WriteLine(s);
SortedList list2 = (SortedList)list.Clone();
Console.WriteLine("\nResultant SortedList...cloned from above list");
foreach(DictionaryEntry d in list){
Console.WriteLine(d.Key + " " + d.Value);
}
}
}输出结果
这将产生以下输出-
SortedList elements... A Jacob B Sam C Tom D John E Tim F Mark G Gary H Nathan I Shaun J David Values... Jacob Sam Tom John Tim Mark Gary Nathan Shaun David Keys... A B C D E F G H I J Resultant SortedList...cloned from above list A Jacob B Sam C Tom D John E Tim F Mark G Gary H Nathan I Shaun J David
示例
现在让我们来看另一个示例-
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args){
SortedList list = new SortedList();
list.Add("One", "IT");
list.Add("Two ", "Operations");
list.Add("Three", "Marketing");
list.Add("Four", "Purchase");
list.Add("Five", "Sales");
list.Add("Six", "Finance");
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in list){
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("\nList of values...SortedList");
IList col = list.GetValueList();
foreach(string res in col) {
Console.WriteLine(res);
}
Console.WriteLine("\nSortedList is read-only? = "+list.IsReadOnly);
SortedList list2 = (SortedList)list.Clone();
Console.WriteLine("\nResultant SortedList...cloned from above list");
foreach(DictionaryEntry d in list){
Console.WriteLine(d.Key + " " + d.Value);
}
}
}输出结果
这将产生以下输出-
SortedList elements... Five Sales Four Purchase One IT Six Finance Three Marketing Two Operations List of values...SortedList Sales Purchase IT Finance Marketing Operations SortedList is read-only? = False Resultant SortedList...cloned from above list Five Sales Four Purchase One IT Six Finance Three Marketing Two Operations
