要从 LinkedList 中删除指定值的第一次出现，代码如下 −
示例
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
LinkedList<string> list = new LinkedList<string>();
list.AddLast("A");
list.AddLast("B");
list.AddLast("C");
list.AddLast("A");
list.AddLast("E");
list.AddLast("F");
list.AddLast("A");
list.AddLast("H");
list.AddLast("A");
list.AddLast("j");
Console.WriteLine("Count of nodes = " + list.Count);
Console.WriteLine("Elements in LinkedList... (Enumerator iterating through LinkedList)");
LinkedList<string>.Enumerator demoEnum = list.GetEnumerator();
while (demoEnum.MoveNext()) {
string res = demoEnum.Current;
Console.WriteLine(res);
}
list.Remove("A");
Console.WriteLine("Count of nodes = " + list.Count);
Console.WriteLine("Elements in LinkedList... (Enumerator iterating through LinkedList)");
demoEnum = list.GetEnumerator();
while (demoEnum.MoveNext()) {
string res = demoEnum.Current;
Console.WriteLine(res);
}
}
}
输出
这将产生以下输出 −
Count of nodes = 10 Elements in LinkedList... (Enumerator iterating through LinkedList) A B C A E F A H A j Count of nodes = 9 Elements in LinkedList... (Enumerator iterating through LinkedList) B C A E F A H A j
示例
让我们看另一个例子:
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
LinkedList<string> list = new LinkedList<string>();
list.AddLast("One");
list.AddLast("Two");
list.AddLast("Three");
list.AddLast("Three");
list.AddLast("Three");
list.AddLast("Four");
Console.WriteLine("Count of nodes = " + list.Count);
Console.WriteLine("Elements in LinkedList... (Enumerator iterating through LinkedList)");
LinkedList<string>.Enumerator demoEnum = list.GetEnumerator();
while (demoEnum.MoveNext()) {
string res = demoEnum.Current;
Console.WriteLine(res);
}
list.Remove("Three");
Console.WriteLine("Count of nodes = " + list.Count);
Console.WriteLine("Elements in LinkedList... (Enumerator iterating through LinkedList)");
demoEnum = list.GetEnumerator();
while (demoEnum.MoveNext()) {
string res = demoEnum.Current;
Console.WriteLine(res);
}
}
}
输出
这将产生以下输出 −
Count of nodes = 6 Elements in LinkedList... (Enumerator iterating through LinkedList) One Two Three Three Three Four Count of nodes = 5 Elements in LinkedList... (Enumerator iterating through LinkedList) One Two Three Three Four
