如何从C#列表中弹出第一个元素？
要弹出列表中的第一个元素，请使用RemoveAt()方法。它从要删除元素的位置中消除了该元素。
设定列表
List<string> myList = new List<string>() {
"Operating System",
"Computer Networks",
"Compiler Design"
};现在使用RemoveAt弹出第一个元素
myList.RemoveAt(0);
让我们看完整的例子。
示例
using System;
using System.Collections.Generic;
using System.Linq;
class Program {
static void Main() {
List<string> myList = new List<string>() {
"Operating System",
"Computer Networks",
"Compiler Design"
};
Console.Write("Initial list...");
foreach (string list in myList) {
Console.WriteLine(list);
}
Console.Write("Removing first element from the list...");
myList.RemoveAt(0);
foreach (string list in myList) {
Console.WriteLine(list);
}
}
}输出结果
Initial list... Operating System Computer Networks Compiler Design Removing first element from the list... Computer Networks Compiler Design
