法律研究从 C# 中的 SortedList 中移除所有元素
要从 SortedList 中移除所有元素，代码如下所示 -
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.Clear();
Console.WriteLine("Count of SortedList (updated) = "+sortedList.Count);
}
}输出
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 Count of SortedList (updated) = 0
示例
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");
Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count);
Console.WriteLine("SortedList elements...");
foreach(DictionaryEntry d in sortedList){
Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
}
sortedList.Clear();
Console.WriteLine("Count of SortedList key-value pairs (updated) = "+sortedList.Count);
}
}输出
这将产生以下输出 -
Count of SortedList key-value pairs = 3 SortedList elements... Key = A, Value = 1 Key = B, Value = 2 Key = C, Value = 3 Count of SortedList key-value pairs (updated) = 0
