C# 如何为更多名称空间的字符串数组分配属性名

C# 如何为更多名称空间的字符串数组分配属性名,c#,xml,C#,Xml,我必须将名称空间thredds的name属性设置为字符串数组。我需要将文件名设置为数组(thredds:dataset name)。 我尝试了doc.Root.Elements()选择dataset并 var names = rows.Select(o => (string)o.Element("name")).ToArray(); 但是不起作用。请建议我。xml是这样的 <thredds:catalog xmlns:thredds="http://www.unidata.uca

您的属性不属于任何名称空间。在代码中,您试图获取元素而不是属性。我认为这样的东西应该可以工作,但还没有测试:
rows.subjections().SelectMany(e=>e.Attribute(“name”).Where(a=>a!=null.ToArray()我尝试了这个,但没有成功
