要在 C# 中使用索引从列表中删除项目，请使用 RemoveAt() 方法。
首先，设置列表 −
List<string> list1 = new List<string>() {
"Hanks",
"Lawrence",
"Beckham",
"Cooper",
};
现在删除第二个位置，即索引 1 处的元素
list1.RemoveAt(1);
让我们看看完整的示例 −
示例
using System;
using System.Collections.Generic;
using System.Linq;
class Program {
static void Main() {
List<string> list1 = new List<string>() {
"Hanks",
"Lawrence",
"Beckham",
"Cooper",
};
Console.Write("Initial list...");
foreach (string list in list1) {
Console.WriteLine(list);
}
Console.Write("Removing element from the list...");
list1.RemoveAt(1);
foreach (string list in list1) {
Console.WriteLine(list);
}
}
}
输出
Initial list... Hanks Lawrence Beckham Cooper Removing element from the list... Hanks Beckham Cooper
