无法通过 XElement 创建名称中带有冒号的 XML 标记

Question

我需要创建名称为 geo:lat 和 geo:long 的 XML 标签来创建 GeoRSS 提要。但它抛出

The ':' character, hexadecimal value 0x3A, cannot be included in a name.

部分代码是这样的：

 XElement("geo:lat", item.Latitude);
 XElement("geo:long", item.Longitude);

如何在 C# 中实现这种格式？

<?xml version="1.0"?>
<?xml-stylesheet href="/eqcenter/catalogs/rssxsl.php?feed=eqs7day-M5.xml" type="text/xsl" 
              media="screen"?>
<rss version="2.0" 
  xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#" 
  xmlns:dc="http://purl.org/dc/elements/1.1/">

Answer 1

geo 是名称 lat 和 lon.

的 namespace 前缀

XNamespace geo = "http://www.w3.org/2003/01/geo/wgs84_pos#";
XNamespace dc= "http://purl.org/dc/elements/1.1/";

XElement(geo + "lat", item.Latitude);
XElement(geo + "long", item.Longitude);

无法通过 XElement 创建名称中带有冒号的 XML 标记
