如何从List<Tuple<DateTime、string>>中删除项目

List<Tuple<DateTime, string>> list = new List<Tuple<DateTime, string>>();

// 添加示例数据
list.Add(new Tuple<DateTime, string>(DateTime.Now, "Item 1"));
list.Add(new Tuple<DateTime, string>(DateTime.Now, "Item 2"));
list.Add(new Tuple<DateTime, string>(DateTime.Now, "Item 3"));

// 遍历列表并删除指定项目
for (int i = list.Count - 1; i >= 0; i--)
{
    if (list[i].Item2 == "Item 2")
    {
        list.RemoveAt(i);
    }
}

List<Tuple<DateTime, string>> list = new List<Tuple<DateTime, string>>();

// 添加示例数据
list.Add(new Tuple<DateTime, string>(DateTime.Now, "Item 1"));
list.Add(new Tuple<DateTime, string>(DateTime.Now, "Item 2"));
list.Add(new Tuple<DateTime, string>(DateTime.Now, "Item 3"));

// 使用LINQ查询语句删除指定项目
list = list.Where(item => item.Item2 != "Item 2").ToList();
