推荐答案

尝试类似

<br />
string[] sArray = (string[])pArrayList.ToArray(typeof(string));<br />
string Result = string.Join(sSeparator, sArray, 0, sArray.Length);<br />
<code>

使用

use

string str = arr.Cast<string>().Aggregate((str1, str2) => str1 + "," + str2);

将为您提供逗号分隔的字符串，但请确保您的arraylist包含所有字符串

will give you comma seprated string but make sure that your arraylist contains all the string

尝试System.String.Concat(myArrayList.ToArray());
