c# - 具有所有属性的 linq to xml 查询

Question

我有一个像这样的 xml 文档

<Products>
  <Product Name="Mobile Device" Code="10000000000000000006">
    <Providers>
        <Provider Name="VODA" Code="VODA">
            <Menus>
                <Menu  Name="Home" Url="TopModelsNew.aspx" DisplayOrder="1" NewWindow="0"/>
                <Menu  Name="Top Queries" Url="TopIssues.aspx" DisplayOrder="2" NewWindow="0"/>
                <Menu  Name="Error Codes" Url="PCErrors.aspx" DisplayOrder="3" NewWindow="0"/>
            </Menus>
        </Provider>
    </Providers>
</Product>

我想在列表中找到产品代码=“10000000000000000006”和供应商代码=“VODA”的所有菜单。
结果应该是这样的

  Name    Url            DisaplayOrder   Home    TopModels      0

I was trying linq to xml as follows

 XDocument xdoc = XDocument.Load(Server.MapPath("~/App_Data/LeftMenu.xml"));
        var products = from product in xdoc.Descendants("Product") where
        new{
                 .....    
            };

我找不到如何获取列表。

Answer 1

XDocument xdoc = XDocument.Load(Server.MapPath("~/App_Data/LeftMenu.xml"));
var menus = from product in xdoc.Descendants("Product")
            where (string)product.Attribute("Code") == "10000000000000000006"
            from provider in product.Descendants("Provider")
            where (string)provider.Attribute("Code") == "VODA"
            from menu in provider.Descendants("Menu")
            select new { 
                Name = (string)menu.Attribute("Name"),
                Url = (string)menu.Attribute("Url"),
                DisplayOrder = (int)menu.Attribute("DisplayOrder")
            };

结果:

  Name            Url                  DisaplayOrder 
  "Home"          "TopModelsNew.aspx"       1
  "Top Queries"   "TopIssues.aspx"          2
  "Error Codes"   "PCErrors.aspx"           3
