该XML无效，因为没有结束标记，但假设您的实际XML有效，您可以这样做：

That XML isn't valid because there are no closing tags, but assuming your actual XML is valid, you can do this:

using System.Xml.Linq;

string xml = @"<language>
<record lang="".net""></record>
<record lang=""java""></record>
<record lang=""php""></record>
</language>";
string temp = string.Join(",", XDocument.Parse(xml).Root.Elements().Select(x => x.Attribute(XName.Get("lang")).Value));

XDocument.Parse将您的字符串解析为 XDocument
.Root 获取根元素，< language>
.Elements（）接受子元素，三个< record> -tags。
.Select（x => x.Attribute（XName.Get（lang））。Value）获取每个元素的lang属性的值。结果是 IEnumerable< string> 。
string.Join 连接这些字符串，逗号作为分隔符。

XDocument.Parse parses your string into an XDocument
.Root takes the root element, <language>
.Elements() takes the child elements, the three <record>-tags.
.Select(x => x.Attribute(XName.Get("lang")).Value) takes the value of the "lang" attribute for each of these elements. The result is an IEnumerable<string>.
string.Join concatenates these strings, with a comma as separator.
