将“列表"项追加到StringBuilder [英] Append 'List' items to StringBuilder

问题描述

我试图用LINQ将List<string>中的项目附加到StringBuilder中:

I tried to append the items in a List<string> to a StringBuilder with LINQ:

items.Select(i => sb.Append(i + ","));

我在此处找到了类似的问题解释了为什么上述方法不起作用，但是我找不到Each的Each或List上的任何类似内容，我可以代替使用.

I found a similar question here which explains why the above doesn't work, but I couldn't find an Each of ForEach or anything similar on List which I could use instead.

是否有一种简单的方法可以做到这一点?

Is there a neat way of doing this in a one-liner?

推荐答案

您可以使用简单的foreach循环.这样，您就可以修改StringBuilder的语句，而不是使用带有副作用的表达式.

You could use a simple foreach loop. That way you have statements which modify the StringBuilder, instead of using an expression with side-effects.

也许String.Join(",", items)可以更好地解决您的问题.

And perhaps your problem is better solved with String.Join(",", items).
