Select XElement where child element has a value
提问by rf_wilson
Given the following XML:
给定以下 XML：
<platforms>
<platform>
<id>1</id>
<price>2.99</price>
</platform>
</platforms>
How can I select the "platform" element as an XElement object based on the child element "id" having a value of "1"?
如何根据值为“1”的子元素“id”选择“平台”元素作为 XElement 对象？
I have got this far:
我已经走了这么远：
XDocument xPlatformXml = new XDocument();
XElement xel = xPlatformXml.Element("platforms").Elements("platform").Where(x => x.Value == "1").SingleOrDefault();
But this is looking for the value to be in "platform" element rather than "id".
但这是在“平台”元素而不是“id”中寻找值。

XDocument xPlatformXml = new XDocument();
XElement xel = xPlatformXml.Element("platforms")
.Elements("platform")
.Where(x => x.Element("id").Value == "1")
.SingleOrDefault();
Or using XElementto intconversion:
或XElement用于int转换：
XDocument xPlatformXml = new XDocument();
XElement xel = xPlatformXml.Element("platforms")
.Elements("platform")
.Where(x => (int)x.Element("id") == 1)
.SingleOrDefault();
