如何转换IEnumerable< string>一个逗号分隔的字符串? [英] How to convert IEnumerable<string> to one comma separated string?

问题描述

说，出于调试目的，我想快速将IEnumerable的内容转换为单行字符串，并用逗号分隔每个字符串项.我可以使用带有foreach循环的辅助方法来完成此操作，但这既不有趣也不简短.可以使用Linq吗?还有其他一些短线方法吗?

Say that for debugging purposes, I want to quickly get the contents of an IEnumerable into one-line string with each string item comma-separated. I can do it in a helper method with a foreach loop, but that's neither fun nor brief. Can Linq be used? Some other short-ish way?

推荐答案

using System;
using System.Collections.Generic;
using System.Linq;

class C
{
    public static void Main()
    {
        var a = new []{
            "First", "Second", "Third"
        };

        System.Console.Write(string.Join(",", a));

    }
}
