Shortest method to convert an array to a string in c#/LINQ
提问by Loris

作为此问题的完全副本关闭。
I have an array/list of elements. I want to convert it to a string, separated by a custom delimitator. For example:
我有一个数组/元素列表。我想将其转换为字符串，由自定义分隔符分隔。例如：
[1,2,3,4,5] => "1,2,3,4,5"
What's the shortest/esiest way to do this in c#?
在 c# 中执行此操作的最短/最简单的方法是什么？
I have always done this by cycling the list and checking if the current element is not the last one before adding the separator.
我总是通过循环列表并在添加分隔符之前检查当前元素是否不是最后一个来完成此操作。
for(int i=0; i<arr.Length; ++i)
{
str += arr[i].ToString();
if(i<arr.Length)
str += ",";
}
Is there a LINQ function that can help me write less code?
有没有可以帮助我编写更少代码的 LINQ 函数？
