遍歷數據集供應商

Question

我有如下一個XML文檔：

<?xml version="1.0" encoding="utf-8" ?> 
<Providers> 
    <Provider> 
     <ProviderType>Email</ProviderType> 
     <ProviderTitle>MyProviderTitle</ProviderTitle> 
     <DeliveryRules> 
      <PersonalDelivery>true</PersonalDelivery> 
     </DeliveryRules> 
     <ProviderConfiguration> 
    <SendTo> 
     <Address>myEmailAddress</Address> 
     <Address>myEmailAddress</Address> 
    </SendTo> 
    </ProviderConfiguration> 
</Provider> 
    <Provider> 
     <ProviderType>Email</ProviderType> 
     <ProviderTitle>MyProviderTitle</ProviderTitle> 
     <DeliveryRules> 
      <PersonalDelivery>true</PersonalDelivery> 
     </DeliveryRules> 
     <ProviderConfiguration> 
    <SendTo> 
     <Address>myEmailAddress</Address> 
     <Address>myEmailAddress</Address> 
    </SendTo> 
    </ProviderConfiguration> 
</Provider> 
</Providers> 

現在我拉進這個使用數據集時：

DataSet dsConfiguration = new DataSet(); 
dsConfiguration.ReadXml("myfile.xml")); 

我如何遍歷提供者？

當涉及到更多的分層數據，你好得多反序列化到一個強類型的對象圖。

這裏是一個非常快的實現，應爲您的示例文件的工作：

[XmlType("Providers")] 
public class Providers : List<Provider> { } 

public class Provider 
{ 
    public string ProviderType { get; set; } 
    public string ProviderTitle { get; set; } 
    public DeliveryRules DeliveryRules { get; set; } 
    public ProviderConfiguration ProviderConfiguration { get; set; } 
} 

public class DeliveryRules 
{ 
    public bool PersonalDelivery { get; set; } 
} 

public class ProviderConfiguration 
{ 
    [XmlArrayItem("Address")] 
    public string[] SendTo { get; set; } 
} 

public static void Main() 
{ 
    var serializer = new XmlSerializer(typeof (Providers)); 
    Providers providers; 
    using (var stream = File.OpenRead("myfile.xml")) 
    { 
     providers = (Providers) serializer.Deserialize(stream); 
    } 
    foreach (var provider in providers) 
    { 
     Console.WriteLine(provider.ProviderTitle); 
     foreach (var address in provider.ProviderConfiguration.SendTo) 
     { 
      Console.WriteLine("\t" + address); 
     } 
    } 
} 

顯然，這種方法需要更多管道的工作，但如果你能得到你的手，描述文檔的格式，那麼你可以將XSD使用XSD.exe工具自動生成所有課程。

foreach (var Provider in dsConfiguration.Tables["Provider"].Rows) 
{ 
    // your code here 
}
