如何在C#中的SortedList中添加键/值对？
要在SortedList中添加键/值对，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");
ICollection col1 = list.Values;
Console.WriteLine("Values...");
foreach(string s in col1)
Console.WriteLine(s);
ICollection col2 = list.Keys;
Console.WriteLine("\nKeys...");
foreach(string s in col2)
Console.WriteLine(s);
}
}出
这将产生以下输出-
Values... Jacob Sam Tom John Tim Mark Gary Nathan Shaun David Keys... A B C D E F G H I J
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 sortedList = new SortedList();
sortedList.Add("A", "1");
sortedList.Add("B", "2");
sortedList.Add("C", "3");
sortedList.Add("D", "4");
sortedList.Add("E", "5");
sortedList.Add("F", "6");
sortedList.Add("G", "7");
sortedList.Add("H", "8");
sortedList.Add("I", "9");
sortedList.Add("J", "10");
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in sortedList){
Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
}
Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count);
sortedList.RemoveAt(3);
Console.WriteLine("\nEnumerator to iterate through the SortedList...");
IDictionaryEnumerator demoEnum = sortedList.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
Console.WriteLine("Count of SortedList key-value pairs (Updated) = "+sortedList.Count);
}
}输出结果
这将产生以下输出-
SortedList elements... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = D, Value = 4 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Count of SortedList key-value pairs = 10 Enumerator to iterate through the SortedList... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Key = E, Value = 5 Key = F, Value = 6 Key = G, Value = 7 Key = H, Value = 8 Key = I, Value = 9 Key = J, Value = 10 Count of SortedList key-value pairs (Updated) = 9
