脚本32/34字符的正则表达式变量

Question

从下面的代码我试图从脚本变量中获取数据。我对“”之间的文字感兴趣

var code =“a37965dcd8421328a767c697448ed735”;

            XPathResult xpathResult = geckoWebBrowser1.Document.EvaluateXPath("/html/body/table[3]/tbody/tr[1]/td[2]/script");
        var foundNodes = xpathResult.GetNodes();
        foreach (var node in foundNodes)
        {
            var x = node.TextContent; // get text text contained by this node (including children)
            GeckoHtmlElement element = node as GeckoHtmlElement; //cast to access.. inner/outerHtml
            string inner = element.InnerHtml;
            string outer = element.OuterHtml;
            String pattent = ".[0-9a-zA-Z]{34}$.";
            Match match = Regex.Match(inner, pattent);

正则表达式是正确的吗？我究竟做错了什么？

Answer 1

你的正则表达式字符串可以尝试使用[0-9a-zA-Z]{32,34}而不是.[0-9a-zA-Z]{34}$.

可以删除.。

Answer 2

您的正则表达式规则可以尝试这样：

bool result = Regex.Match(inner, @"^[0-9a-zA-Z]{32,34}$").Success;
Console.WriteLine(result);

如果结果等于true，它匹配成功！
