c# - 正则表达式替换多个模式

Question

我是编程新手，需要一些帮助 ;-)如何替换 string 中的多个模式？

例子:

static void Main(string[] args)
{
  string input = "this is a test AAA one more test adakljd jaklsdj BBB sakldjasdkj CCC";
  string [] pattern = {"AAA", "BBB","CCC"};
  string replacement = "XXX";

  string result = null;
  for (int i = 0; i < pattern.Length; i++)
  {
    result = Regex.Replace(input, pattern[i], replacement);
  }

  Console.WriteLine(result);
}

想要的结果:

this is a test XXX one more test adakljd jaklsdj XXX sakldjasdkj XXX

但是我得到:

this is a test AAA one more test adakljd jaklsdj BBB sakldjasdkj XXX

提前感谢您的帮助!

你不需要正则表达式，你可以简单地使用Replace:

string input = "this is a test AAA one more test adakljd jaklsdj BBB sakldjasdkj CCC";
string replaced = input.Replace("AAA", "XXX").Replace("BBB", "XXX")...
