Question

我需要在字符串1中找到匹配的子字符串，忽略空格和字符，如 - 。

我的例子是：

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";

我需要匹配字符串1中的string2并将其从字符串1中删除。

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

非常感谢

Answer 1

这似乎适用于您的示例，但您应该更多地测试它。我想你总是希望替换符合相同的模式，其中删除了额外的空格和“ - ”字符。

// 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

这可能不是最好的方法，但是：

// 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)

不确定忽略“ - ”字符。尝试“Regex Buddy”，它对编写正则表达式非常有帮助。它甚至有一个“复制模式为C＃正则表达式”选项。

这应该可以解决问题：

1 = 1.Replace（2，string.Empty）;

删除匹配的子字符串忽略空格
