Question

我需要删除一个相配的子,如果发现它无视像白人空间和果园这样的白人空间。

例如:

string 1="The LawyerWhat happened to A&O s first female partner?The LawyerWhen Clare Maurice was made up at Allen & Overy (A&O) in 1985 she was the sole female partner at the firm. Twenty-five years later, gradual change in the";

下面的插图2与插图1相匹配,删除插图1。

string 2="What happened to A&O s first female partner? - The Lawyer";

非常感谢

Answer 1

这似乎与你一样,但你应当对此进行更多的测试。我认为,你总是期望更换工作遵循同样的模式,排除额外空间和“-”特性。

// renamed your variables: 1 is "input", 2 is "replaceValue"
string pattern = Regex.Replace(replaceValue.Replace("-", ""), @"s{2,}", "");
pattern = Regex.Escape(pattern);
string result = Regex.Replace(input, pattern, "");

Answer 2

这可能是这样做的最佳途径,但:

// I renamed the strings to source and pattern because 1 and 2 wouldn t be very clear
string result = Regex.Replace(source, Regex.Escape(pattern).Replace(" ", "[s]*?"));
// Google shows we have an option such as
string result = Regex.Replace(source, Regex.Escape(pattern), RegexOptions.IgnoreWhiteSpace)

;

不要忽视“-”性质。开展“Regex Buddy”活动,对撰写定期表述毫无帮助。它甚至有一个“C# regex”方案。

Answer 3

这应当做到:

1 = 1.Replace(2, string.Empty);
