我有一个包含单词的字符串。
string attrs = "AAA,BBB,CCC,DDD"
我有想要检查其中一个对象是否存在于此字符串中的对象列表,如果没有,则过滤掉该对象
List<Vehicle> vehiclesSort = new List<Vehicle>();
所以我试着做这样的事情:
vehiclesSort = vehiclesSort.Where(o => o.Class.Contains(attrs))
但是编译错误,
此外我需要检查attrs中是否存在Class属性,而不是如果属性中存在attrs,那么我认为我的方向不正确
请协助,

我稍微修改了你的查询。这是一个例子:
List<Vehicle> vehiclesSort = new List<Vehicle>()
{
new Vehicle() {Class="VW" },
new Vehicle() {Class="BBB" },
new Vehicle() {Class="BMW" },
new Vehicle() {Class="DDD" },
new Vehicle() {Class="AUDI" },
};
string attrs = "AAA,BBB,CCC,DDD";
vehiclesSort = vehiclesSort.Where(x => attrs.Split(',').Contains(x.Class)).ToList();
Vehicle
上课:
public class Vehicle
{
public string Class { get; set; }
}

我认为你正在寻找像这样的东西
class Program
{
static void Main(string[] args)
{
string attrs = "AAA,BBB,CCC,DDD";
List<Vehicle> vehiclesSort = new List<Vehicle>();
vehiclesSort.Add(new Vehicle(attrs));
vehiclesSort.Add(new Vehicle("bbb"));
vehiclesSort = vehiclesSort.Where(o => o.attr.Contains(attrs)).ToList();
foreach (var VARIABLE in vehiclesSort)
{
Console.WriteLine(VARIABLE.attr);
}
}
}
public class Vehicle
{
public Vehicle(string attr1)
{
this.attr = attr1;
}
public string attr;
}
