法律研究从 C# 中的 SortedList 中的指定索引中删除
若要从 SortedList 的指定索引中删除，代码如下 −
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("
Enumerator 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
这将生成以下输出 −
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
示例
让我们看另一个例子 −
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args) {
SortedList sortedList = new SortedList();
sortedList.Add("One", "Mouse");
sortedList.Add("Two", "Keyboard");
sortedList.Add("Three", "Headphone");
sortedList.Add("Four", "Speakers");
sortedList.Add("Five", "RAM");
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(1);
sortedList.RemoveAt(2);
Console.WriteLine("
Enumerator 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
这将生成以下输出 −
SortedList elements... Key = Five, Value = RAM Key = Four, Value = Speakers Key = One, Value = Mouse Key = Three, Value = Headphone Key = Two, Value = Keyboard Count of SortedList key-value pairs = 5 Enumerator to iterate through the SortedList... Key = Five, Value = RAM Key = One, Value = Mouse Key = Two, Value = Keyboard Count of SortedList key-value pairs (Updated) = 3
