我正在开发的.NET应用程序，用户可以提供事后被用来验证输入数据的普通防爆pressions。

I'm developing an application in .NET where the user can provide Regular Expressions that are afterwards used to validate input data.

我需要一种方法来知道，如果一个普通的前pression实际上是适用于.NET正则表达式引擎。

I need a way to know if a regular expression is actually valid for the .net regex engine.

感谢您的帮助

推荐答案

只是试图编译给定的正则表达式。你可以通过创建正则表达式对象，并传递模式给它。下面是一个示例code：

Just try to compile the given regex. You can do that by creating the Regex object and passing the pattern to it. Here's a sample code:

public static bool IsRegexPatternValid(String pattern)
{
    try
    {
        new Regex(pattern);
        return true;
    }
    catch { }
    return false;
}
