C#:字符串[]到分隔字符串。有单行线吗?

对于阵列,可以使用:

string.Join(", ", strArray);

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();
}

strArray.Flatten(", ");

你可以用静电 String.Join 方法:

String strNew = String.Join(chDelimiter, strArray);

编辑:回应评论 Concat . 举个例子:

//define my two arrays...
string[] strArray = { "Hi", "how", "are", "you" };
string[] strArray2 = { "Hola", "como", "esta", "usted" };

//Concatenate the two arrays together (forming a third array) and then call join on it...
string strNew = String.Join(",", strArray.Concat(strArray2));

希望这有帮助!

看一看 String.Join()

您的样品必须如下所示:

        string delimiter = ","
        string[] strArray = { "Hi", "how", "are", "you" };
        string strNew = String.Join(delimiter, strArray);

使用 String.Join

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

var comSeparatedStrings = strings.Aggregate((acc, item) => acc + ", " + item);
