Je suis en train de pares l'alimentation en utilisant XDocument .. Je veux juste obtenir le CategoryId, CategoryName, Description et image.

Je possède ce code, mais il ne fonctionne pas ..

//Namesapces 
       //xml:base="http://localhost:32026/Northwind/Northwind.svc/" 
       XNamespace nsBase = "http://localhost:32026/Northwind/Northwind.svc/"; 

       //xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" 
       XNamespace d = "http://schemas.microsoft.com/ado/2007/08/dataservices"; 

       //xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" 
       XNamespace m = "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"; 

       //xmlns="http://www.w3.org/2005/Atom 
       XNamespace atom = "http://www.w3.org/2005/Atom"; 


        var xdoc = XDocument.Load("xmlfile stream"); 

        foreach (var entity in xdoc.Descendants(atom + "entry")) { 
         var properties = entity.Descendants(m + "properties"); 
         var category = new CategoryModel() { 
          Id = Convert.ToInt32(properties.Elements(d + "CategoryID")), 
          Name = properties.Elements(d + "CategoryName").ToString(), 
          Description = properties.Elements(d + "Description").ToString(), 
         }; 
         Items.Add(category); 
        } 

J'ai essayé de cette façon aussi, mais ne fonctionne toujours pas

var properties = entity.Elements(atom + "content").Elements(m + "properties"); 

Answer 1

Je l'ai .. Je typé « Elements » au lieu de "Element" mal ..

Voici le code correct ..

foreach (var entity in xdoc.Descendants(atom + "entry")) { 
         var properties = entity.Element(atom + "content").Element(m + "properties"); 
         var category = new CategoryModel() { 
          Id = Convert.ToInt32(properties.Element(d + "CategoryID").Value), 
          Name = properties.Element(d + "CategoryName").Value, 
          Description = properties.Element(d + "Description").Value, 
         }; 
         Items.Add(category); 
        }
