是的，可以使用 LINQ:

Yes, it's possible using LINQ:

var memberNames = membersIdList.Cast<XmlNode>()
                               .Select(node => node.InnerText)
                               .Select(value => int.Parse(value))
                               .Select(id => library.GetMemberName(id))
                               .ToList();

Cast() 调用是必要的，因为XmlNodeList 没有实现通用的IEnumerable，所以你必须明确将其从非泛型 IEnumerable 转换为泛型集合.

Cast<XmlNode>() call is necessary, because XmlNodeList does not implement generic IEnumerable<T>, so you have to explicitly convert it to generic collection from non-generic IEnumerable.

是的，如果需要，您可以将所有 Select 调用合并为一个:

And yes, you can merge all Select calls into one if you want:

var memberNames = membersIdList.Cast<XmlNode>()
                               .Select(x => library.GetMemberName(int.Parse(x.InnerText)))
                               .ToList();
