我想获取所有文本框名称和值.这是我尝试过的,它不起作用:
XDocument data = XDocument.Load("..\\..\\testxml.rdl");
var elements = from c in data.Elements("ReportItems")
select c;
foreach (var element in elements)
{
Console.WriteLine("Element : " + element.Attribute("Name").Value);
}
Console.ReadKey();
但是当我将查询更改为这样的东西时
var elements = from c in data.Elements().Elements().ElementAt(0).Elements().ElementAt(0).Elements()
select c;
有用.
在这方面的任何帮助非常感谢.
编辑:在答案的帮助下,我能够得到理想的结果.非常感谢 :)
XDocument data = XDocument.Load("..\\..\\testxml.rdl");
XNamespace ns = data.Root.Name.Namespace;
var elements = from c in data.Descendants(ns + "Textbox")
select c;
foreach (var element in elements)
{
Console.WriteLine("Element : " + element.Attribute("Name").Value);
}
Console.ReadKey();
TIA.

您需要考虑名称空间:
XNamespace df = data.Root.Name.Namespace;
然后使用在根元素上定义的命名空间中df + "foo"选择具有本地名称foo的元素.
如前所述,您可能希望选择后代,而不是子元素:
var elements = from c in data.Descendants(df + "Textbox")
select c;
