无法写入创建文件并向其写入 xml
本文关键字:xml 创建 文件 | 更新日期: 2023-09-27 18:30:46
我写iOS应用程序。
我尝试创建xml并将其写入文件。
我使用以下代码执行此操作。
var documentsPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
var filePath = System.IO.Path.Combine(documentsPath, "myFile.xml");
XmlDocument doc = new XmlDocument ();
XmlElement el = (XmlElement)doc.AppendChild (doc.CreateElement ("Order"));
el.SetAttribute ("CallConfirm", "1");
el.SetAttribute ("PayMethod", "");
el.SetAttribute ("QtyPerson", "");
el.SetAttribute ("Type", "1");
el.SetAttribute ("PayStateID", "0");
el.SetAttribute ("Remark", "{StreetName} , ..");
el.SetAttribute ("RemarkMoney", "0");
el.SetAttribute ("TimePlan", "");
el.SetAttribute ("Brand", "1");
el.SetAttribute ("DiscountPercent", "0");
el.SetAttribute ("BonusAmount", "0");
el.SetAttribute ("Department", "");
XmlElement el2 = (XmlElement)el.AppendChild (doc.CreateElement ("Customer"));
el2.SetAttribute ("Login", "");
el2.SetAttribute ("FIO", "{FIO}");
XmlElement el3 = (XmlElement)el.AppendChild (doc.CreateElement ("Address"));
el3.SetAttribute ("CityName", "{CityName}");
el3.SetAttribute ("StationName", "");
el3.SetAttribute ("StreetName", "{StreetName}");
el3.SetAttribute ("House", "{HouseName}");
el3.SetAttribute ("Corpus", "");
el3.SetAttribute ("Building", "");
el3.SetAttribute ("Flat", "{FlatName}");
el3.SetAttribute ("Porch", "");
el3.SetAttribute ("Floor", "");
el3.SetAttribute ("DoorCode", "");
XmlElement el4 = (XmlElement)el.AppendChild (doc.CreateElement ("Phone"));
el4.SetAttribute ("Code", "{Code}");
el4.SetAttribute ("Number", "{Phone}");
XmlElement el5 = (XmlElement)el.AppendChild (doc.CreateElement ("Products"));
Console.WriteLine ("TUT");
//File.WriteAllText(filePath, doc.OuterXml);
//doc.Save ("myfile.xml");
doc.Save (filePath);
Console.WriteLine (doc.OuterXml);
Console.WriteLine (filePath);
当我启动我的应用程序时,它崩溃了。
我认为这是因为我有错误的代码来创建 xml 文件。
如何正确书写?
对 xml 文件使用原始访问是一个坏主意。你应该使用对象模型,它有很多优点。为您提供的解决方案:
public class Customer
{
public String Login{get;set;}
public String FIO{get;set;}
}
public class Phone{
public String Code{get;set;}
public String Number{get;set;}
}
public class Address{
public String CityName{get;set;}
public String StationName{get;set;}
public String StreetName{get;set;}
public String House{get;set;}
public String Corpus{get;set;}
public String Building{get;set;}
public Int32 Flat{get;set;}
public String Porch{get;set;}
public Int32 Floor{get;set;}
public String DoorCode { get; set; }
}
public class Order
{
public Int32 CallConfirm {get;set;}
public String PayMethod{get;set;}
public String QtyPerson{get;set;}
public Int32 Type {get;set;}
public Int32 PayStateID {get;set;}
public String Remark {get;set;}
public Int32 RemarkMoney {get;set;}
public String TimePlan {get;set;}
public Int32 Brand {get;set;}
public Int32 DiscountPercent {get;set;}
public Int32 BonusAmount {get;set;}
public String Department {get;set;}
public Customer Customer {get;set;}
public Address Address {get;set;}
public Phone Phone { get; set; }
public List<String> Products { get; set; }
}
static void Main(string[] args)
{
var order = new Order()
{
Address = new Address()
{
CityName = "Yeah"
},
Phone = new Phone()
{
Code = "251"
},
Customer = new Customer()
{
FIO = "Lev Leshenko"
},
CallConfirm = 1
//...
};
var s = new XmlSerializer(typeof(Order));
using(var f = File.Open("test.xml",FileMode.Create)){
s.Serialize(f, order);
}
}
