在字符串中查找子字符串，并在其后跟随搜索的句子

Question

在C＃中，什么是在字符串中查找子字符串并在单词之后跟随搜索到的句子（例如在字符串中）检索子字符串的正确方法：

 string str = "On the screen the faint, old, robed figure of Mercer toiled upward, and all at once a rock sailed past him.";

搜索子字符串：

 string find = "figure of";

获得所需的输出：

 figure of Mercer

Answer 1

您可以尝试此模式([inputString] +(\\w+))

使用正则表达式group和空格获取单词。

string search = "figure of";
string str = "On the screen the faint, old, robed figure of Mercer toiled upward, and all at once a rock sailed past him.";
string regex_Str = string.Format("({0} +([\\w+]+))", search);
var result = new Regex(regex_Str).Match(str);
Console.WriteLine(result.Value);
