C＃：字符串[]为分隔字符串。是否有一个单行？ [英] C#: string[] to delimited string. Is there a one-liner?

问题描述

我想preFER是一样的东西：

What I'd prefer is something like:

string[] strArray = {"Hi", "how", "are", "you"};
string strNew = strArray.Delimit(chDelimiter);

然而，不存在这样的功能。我看过了MSDN和没有看着我，将执行相同的操作功能。我看着StringBuilder的，并再次，没有站出来给我。有谁知道一个不是极其复杂单行，使数组的分隔字符串。感谢您的球员的帮助。

However, there is no such function. I've looked over MSDN and nothing looked to me as a function that would perform the same action. I looked at StringBuilder, and again, nothing stood out to me. Does anyone know of a not to extremely complicated one liner to make an array a delimited string. Thanks for your guys' help.

更新：哇，哈哈，是我不好。我一直在寻找的。加入该阵列本身上，这是窃听了我的地狱中。我甚至没有看的string.join。多谢你们。一旦它可以让我接受我应。 preciate的帮助。

UPDATE: Wow, lol, my bad. I kept looking at the .Join on the array itself and it was bugging the hell out of me. I didn't even look at String.Join. Thanks guys. Once it allows me to accept I shall. Preciate the help.

推荐答案

对于数组，你可以使用：

For arrays, you can use:

string.Join(", ", strArray);

就个人而言，我使用，我可以适用于所有类型的枚举集的扩展方法：

Personally, I use an extension method that I can apply to enumerable collections of all types:

public static string Flatten(this IEnumerable elems, string separator)
{
    if (elems == null)
    {
        return null;
    }

    StringBuilder sb = new StringBuilder();
    foreach (object elem in elems)
    {
        if (sb.Length > 0)
        {
            sb.Append(separator);
        }

        sb.Append(elem);
    }

    return sb.ToString();
}

...我用像这样：

...Which I use like so:

strArray.Flatten(", ");
