C# 如何将XML属性反序列化为对象,然后遍历对象
我希望能够对XML文件中的车辆进行“操作”。理想情况下,我希望遍历所有车辆并计算它们的价格,然后更改它们是否在销售。然后,这些值将显示在UI中。我的代码反序列化XML文件,但我无法访问车辆的任何属性。我不需要将对象序列化回XML 我已尝试Console.WriteLine价格,但是当我运行代码时,它返回为0。我是否应该创建一系列ResponseGraphyVendorRegionVehicle?然后以某种方式将该类型的对象添加到数组中 这是XML文件:C# 如何将XML属性反序列化为对象,然后遍历对象,c#,xml,visual-studio,xmlserializer,C#,Xml,Visual Studio,Xmlserializer,我希望能够对XML文件中的车辆进行“操作”。理想情况下,我希望遍历所有车辆并计算它们的价格,然后更改它们是否在销售。然后,这些值将显示在UI中。我的代码反序列化XML文件,但我无法访问车辆的任何属性。我不需要将对象序列化回XML 我已尝试Console.WriteLine价格,但是当我运行代码时,它返回为0。我是否应该创建一系列ResponseGraphyVendorRegionVehicle?然后以某种方式将该类型的对象添加到数组中 这是XML文件: <?xml version="1.0

请让我知道如何更好地解释我自己。如果这些都没有意义,我道歉-欢迎来到我的周末lol
谢谢。您需要使用内置在.Net中的XML序列化程序 首先创建一个类来表示XML文档数据:
public class Response
{
public Geography Geography {get; set;}
}
public class Geography
{
public Vendor Vendor{get;set;}
}
public class Vendor
{
public List<Region> Regions {get;set;}
}
public class Region
{
}
然后,您可以迭代地理对象上的所有属性和内容。您需要使用内置在.Net中的XML序列化程序 首先创建一个类来表示XML文档数据:
public class Response
{
public Geography Geography {get; set;}
}
public class Geography
{
public Vendor Vendor{get;set;}
}
public class Vendor
{
public List<Region> Regions {get;set;}
}
public class Region
{
}
然后,您可以迭代地理对象上的所有属性和内容。因为您的xml根显然是一个
响应
而不是响应图形
,所以您必须反序列化为该类型:
string path = @"c:\XMLFile1.xml";
XmlSerializer ser = new XmlSerializer(typeof(response);
ResponseGeographyVendor i;
using (Stream reader = new FileStream(path,FileMode.Open))
{
i = ((Response)ser.Deserialize(reader)).Geography.Vendor;
Console.WriteLine(i.Price);
Console.ReadLine();
}
序列化程序只能处理整个xml文档。你不能只写或读其中的一部分。所以只需使用xml,将其序列化为
string path = @"c:\XMLFile1.xml";
XmlSerializer ser = new XmlSerializer(typeof(response);
ResponseGeographyVendor i;
using (Stream reader = new FileStream(path,FileMode.Open))
{
i = ((Response)ser.Deserialize(reader)).Geography.Vendor;
Console.WriteLine(i.Price);
Console.ReadLine();
}
var vehicle = i.Region[1].Vehicle[2];
