要弹出列表中的第一个元素，请使用 RemoveAt() 方法。它会从您想要移除元素的位置移除该元素。
设置列表
List<string> myList = new List<string>() {
"Operating System",
"Computer Networks",
"Compiler Design"
};
现在使用 RemoveAt(0) 弹出第一个元素
myList.RemoveAt(0);
让我们看一下完整的例子。
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
Initial list... Operating System Computer Networks Compiler Design Removing first element from the list... Computer Networks Compiler Design
