推荐答案

如果你的意思是你有一个字符串数组，并且想要找到包含子字符串的第一个字符串，那么这并不困难：

If you mean that you have an array of strings, and you want to find the first string containing a substring, then it's not difficult:

string[] words = new string[] { "hello there", "this is text", "to find a substring", "or at least", "the first example substring" };
string first = words.FirstOrDefault(s => s.Contains("sub"));
if (first != null) Console.WriteLine(first);
