我需要创建名称为geo:lat
和geo:long
的XML标签,以创建GeoRSS提要。但是它会抛出
名称中不能包含十六进制值0x3A的':'字符。
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#"

答案 0 :(得分:6)
geo
是名称lat
和lon
的{{3}}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);
