使用正则表达式将字符串映射到功能 [英] Mapping Strings to Functionality Using Regular Expressions

问题描述

我有一个字符串和多个正则表达式，例如一个正则表达式，它检查字符串是否仅为数字，是否以字符X开头等等.根据匹配的正则表达式，我运行不同的代码，如下所示:

I have a string and multiple regex's, for example a regex that checks if the string is a number only, if it starts with character X and so on. I have different codes running depending on what regex gets matched, like this:

if (Regex.IsMatch(myString, regex1))
{
    //number
}
else if (Regex.IsMatch(myString, regex2))
{
    //something else
}
else if (Regex.IsMatch(myString, regex3))
{
    //something else
}

，依此类推.但是，这看起来很笨拙，因为我要经历10个正则表达式，所以我可以使用switch/case做同样的事情吗?如果是这样，我可以举个例子吗?

and so on. However, this looks very clunky as I have like 10 regex's to go through, so can I do the same thing using switch/case? If so, can I be provided with an example?

我正在使用.NET 2.0和WinForms.

I am using .NET 2.0 and WinForms.

推荐答案

无法按照您的描述进行操作，因为switch只能与以下各项一起使用:bool，char字符串，int，enum或相应的可为null的类型.

This cannot be done as you describe because switch can only be used with: bool, char string, int, enum or a corresponding nullable type.
