使用Linq解析XML数据到Xml

Question

我想解析使用LINQ到Xml的以下xml文档，但我似乎无法得到任何输出。

<ArrayOfCustomProperty xmlns="http://schemas.datacontract.org/2004/07/PropertySearchRestfulService.PropertySearchSoapService" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> 
    <CustomProperty> 
    <addressLine1Field>The Boulevard,</addressLine1Field> 
    <addressLine2Field>Imperial Wharf</addressLine2Field> 
    <addressLine3Field>Fulham</addressLine3Field> 
    <descriptionField>This impressive penthouse apartment is arranged across two floors in the prestigious Chelsea Vista Development with numerous roof terraces with panoramic views across London. For viewing times, call to arrange your allocated appointment time.</descriptionField> 
    <forRentOrSaleField>Sale </forRentOrSaleField> 
    <furnitureField>Furnished</furnitureField> 
    <gardenSizeField>0</gardenSizeField> 
    <hasGardenField>false</hasGardenField> 
    <numberOfBathroomsField>5</numberOfBathroomsField> 
    <numberOfBedroomsField>4</numberOfBedroomsField> 
    <postCodeField>SW6 5TG</postCodeField> 
    <propertyImagesField xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays"> 
     <a:string>House1.jpg</a:string> 
    </propertyImagesField> 
    <propertyTypeField /> 
    <rentModeField /> 
    <rentPriceField>0</rentPriceField> 
    <salePriceField>267000</salePriceField> 
    <statusField>Available</statusField> 
    </CustomProperty> 

下面是我试图解析XML数据

properties = from property in xmlProperty.Descendants("CustomProperty") 

      select new Property 
      { 

       ("propertyImagesField").Value; 
       Description = property.Element("descriptionField").Value, 

       PropertyType = property.Element("propertyTypeField").Value, 
       AddressLine1 = property.Element("addressLine1Field").Value, 
       AddressLine2 = property.Element("addressLine2Field").Value, 
       AddressLine3 = property.Element("addressLine3Field").Value, 
       PostCode = property.Element("postCodeField").Value, 
       NumberOfBedrooms = property.Element("numberOfBedrsoomField").Value, 
       NumberOfBathrooms = property.Element("numberOfBathroomsField").Value, 
       Furniture = property.Element("furnitureField").Value, 
       HasGarden = property.Element("hasGardenField").Value, 
       GardenSize = property.Element("gardenSizeField").Value, 
       ForRentOrSale = property.Element("forRentOrSaleField").Value, 
       RentPrice = property.Element("rentPriceField").Value, 
       RentMode = property.Element("rentModeField").Value, 
       SalePrice = property.Element("salePriceField").Value, 
       Status = property.Element("statusField").Value 

      }; 

//的属性列表绑定到数据网格 propertyGrid.ItemsSource = properties.ToList（）的方式;

任何帮助将大大appeciated。

（您select条款的开始是目前无效，但我会忽略...）

你不采取命名空间考虑：

XNamespace ns = "http://schemas.datacontract.org/2004/07/" + 
       "PropertySearchRestfulService.PropertySearchSoapService"; 

properties = from property in xmlProperty.Descendants(ns + "CustomProperty") 
      ... 
      // Later on, the same problem when selecting... 
      Description = property.Element(ns + "descriptionField").Value, 

注意呼叫properties.ToString不会给你任何有用的东西。你需要：

foreach (var property in properties) 
{ 
    MessageBox.Show(property.ToString()); 
} 

...甚至这是假设你Property类覆盖ToString。

编辑：短，但完整的程序来证明它的工作：

using System; 
using System.Linq; 
using System.Xml.Linq; 

class Program 
{ 
    static void Main(string[] args) 
    { 
     XDocument doc = XDocument.Load("test.xml"); 
     XNamespace ns = "http://test-namespace1"; 

     var query = 
       from element in doc.Descendants(ns + "CustomProperty") 
       select new { 
       Description = element.Element(ns + "descriptionField").Value, 
       Furniture = element.Element(ns + "furnitureField").Value 
       }; 

     foreach (var record in query) 
     { 
      Console.WriteLine(record); 
     } 
    } 
} 

示例XML：

<ArrayOfCustomProperty xmlns="http://test-namespace1" 
         xmlns:i="http://test-namespace2"> 
    <CustomProperty> 
    <descriptionField>First house</descriptionField> 
    <furnitureField>Furnished</furnitureField> 
    </CustomProperty> 
    <CustomProperty> 
    <descriptionField>Second house</descriptionField> 
    <furnitureField>Unfurnished</furnitureField> 
    </CustomProperty> 
</ArrayOfCustomProperty> 

输出：

{ Description = First house, Furniture = Furnished } 
{ Description = Second house, Furniture = Unfurnished }
