怎么将string[]转换成char[]

怎么将string[]转换成char[].
有个题目:

string source = "A B C 400 500 600 10 20 30";
            Dictionary<string, string> replec = new Dictionary<string, string>();
            replec.Add("A", "X");
            replec.Add("B", "Y");
            replec.Add("C", "Z");
/*    在这个位置写代码,使之控制台输出 X Y Z 100 200 300 1 2 3                             */
foreach (string key in replec.Keys)
            {
                source = source.Replace(key, replec[key]);
            }
            Console.WriteLine(source);

谢谢了. 怎么写啊.

string转 char[]
string.ToCharArray();
400 500 600 =>100 200 300 ?

[wuyq11]

string str="";
foreach(string s in source.Split(' '))
{
if (Regex.IsMatch(s, @"\d+"))
str += s.Length > 2 ? (Convert.ToInt16(s) - 300).ToString() + " " : s.TrimEnd('0') + " ";
else str += s + " ";
}

看晕了，转换规则是什么?

要不你直接写
Console.WriteLine("X Y Z 100 200 300 1 2 3");

replec.Add("400", "1000");
replec.Add("500", "2000");
replec.Add("600", "3000");
replec.Add("10", "1");
replec.Add("20", "2");
replec.Add("30", "3");
