如何在c#中连接字符串

Question

我有一个名为people的字符串列表.我想将它们组合起来并用逗号分隔它们并将它们存储在一个名为totalPeopleNames的变量中.这就是我所拥有的,但它不起作用:

string totalPeopleNames = null;

foreach(var person in people)
{
    Enumerable.Concat(totalPeopleNames, ", " + person.Person.FullName);
}

Answer 1

var totalPeopleNames = String.Join(", ",people.Select(p=>p.Person.FullName))
