.Net 正则表达式用于 \\" "\\ 之间的字符串
[英].Net regex for string between \" "\
问题描述
I have been trying to get the id from the following text
我一直在尝试从以下文本中获取id
<body id=\"body\" runat=\"server\">
In C# using substring or even Regex, but nothing seems to be working.在 C# 中使用子字符串甚至 Regex，但似乎没有任何效果。 No matter what regex i use, i always get the whole line back.无论我使用什么正则表达式，我总是能得到整行。 I have been trying to use ^id , ^id.* , ^id=\\\\\\\\\\\\\\\\.* and id=.* but they don't either work or give me the desired output.我一直在尝试使用^id 、 ^id.* 、 ^id=\\\\\\\\\\\\\\\\.*和id=.*但它们既不工作也不给我所需的输出。 Is there any way i can get the id portion from this text which is enclosed between the characters \\" "\\ ?有什么办法可以从包含在字符\\" "\\之间的文本中获取 id 部分？

Try this:尝试这个：
string htmlString = "<body id=\"body\" runat=\"server\">";
Regex regex = new Regex("id=\"(.*?)\"");
Match m = regex.Match(htmlString);
Group g = m.Groups[1];
string id = g.ToString();
Console.WriteLine(id); //body
