需要 LINQ 查询才能读取返回列表的 XML 文件

Question

在这个XML文件中，我必须获取列表中的所有源dll。我正在尝试以下查询。

将 appManifest Dim As String = new System.IO.StreamReader（Application.GetResourceStream（New System.Windows.Resources.StreamResourceInfo（e.Result， Nothing）， new Uri（"AppManifest.xaml"， UriKind.Relative））.流）。ReadToEnd（）

Dim deploymentRoot As XElement = XDocument.Parse（appManifest）.根**将部件调暗为 List（Of XElement） = （来自 assembly Parts In _ deploymentRoot.Elements（）。元素（） 选择装配零件）。ToList（）**

但帕特尔斯包含计数。它不是一个列表。我该怎么做？

下面是 XML 文档。

<Deployment xmlns="http://schemas.microsoft.com/client/2007/deployment" 
            RuntimeVersion="4.0.50826.0">

Answer 1

你有没有尝试过使用 xpath？查询将是这样的//AssemblyPart/[Source]

XPath 一般： http://www.w3schools.com/xpath/default.asp

XPath & .Net： http://www.developer.com/net/net/article.php/3383961/NET-and-XML-XPath-Queries.htm

干杯

使用 LINQ 的答案位于：http://forums.asp.net/t/1681678.aspx/1

从那里复制：

Dim assemblySources  = From aPart In XDocument.Load().Descendants("AssemblyPart") select a.Attribute("Source").Value  
For Each item As string In assemblySources 
  Console.WriteLine(item)  
Next
