如题  我们可以用Split分割字符串，但是怎么把数组转换成字符串呢  求大神解答

char[] delimit = new char[] { ' ' };

string s10 = "The cat sat on the mat.";

foreach (string substr ins10.Split(delimit))

{

   System.Console.WriteLine(substr);

}

//-------------------------------输出结果------------------------------------------//

The

cat

sat

on

the

mat.

//-------------------------------输出结果------------------------------------------//

string.join("链接字符"，char[]args)  StringBuilder 拼接都行
