C＃XML Serilization和追加新的數據

但是一個XML文件，這是我所得到的（一行）：

<?xml version="1.0" encoding="utf-8"?><!--This file is generated by the program.--><root><OFBM time="9:15" date="22.06.2016"><folder>file:///C:/Program Files (x86)/Cisco/Cisco AnyConnect Secure Mobility Client</folder><folder>file:///C:/Arduino223</folder></OFBM></root>

我的代碼：

public void CreateXML() 
     { 
      XmlWriter writer = XmlWriter.Create(@"C:\Users\Alek\Dropbox\D\Debug\product.xml"); 

      writer.WriteStartDocument(); 

      writer.WriteComment("This file is generated by the program."); 

      writer.WriteStartElement("root"); 
      writer.WriteStartElement("OFBM"); 
      writer.WriteAttributeString("time", "9:15"); 
      writer.WriteAttributeString("date", "22.06.2016"); 
      writer.WriteElementString("folder", @"file:///C:/Program Files (x86)/Cisco/Cisco AnyConnect Secure Mobility Client"); 
      writer.WriteElementString("folder", @"file:///C:/Arduino223"); 
      writer.WriteEndElement(); 
      writer.WriteEndElement(); 
      writer.WriteEndDocument(); 
      writer.Flush(); 
      writer.Close(); 
     }

我該如何追加新數據？而不是每次都創建一個新的XML。

看看這個文章 - http://stackoverflow.com/questions/4094180/indentation-and-new-line-command-for-xmlwriter-in-c-sharp。有一種添加縮進的解決方案。第二個問題：http://stackoverflow.com/questions/20922835/appending-an-existing-xml-file-with-xmlwriter - 如何將xml添加到現有文件。 – VitaliyK

添加一些設置，以達到你想在你的XML文件來實現縮進：

//I added this part (XmlWriterSettings): 
XmlWriterSettings mySettings = new XmlWriterSettings(); 
mySettings.Indent = true; 
mySettings.IndentChars = (" "); 
mySettings.CloseOutput = true; 
mySettings.OmitXmlDeclaration = true; 

//Added the settings you intialize and set on your XmlWriter: 
XmlWriter writer = XmlWriter.Create(@"C:\Users\Alek\Dropbox\D\Debug\product.xml", mySettings); 

writer.WriteStartDocument(); 

writer.WriteComment("This file is generated by the program."); 

writer.WriteStartElement("root"); 
writer.WriteStartElement("OFBM"); 
writer.WriteAttributeString("time", "9:15"); 
writer.WriteAttributeString("date", "22.06.2016"); 
writer.WriteElementString("folder", @"file:///C:/Program Files (x86)/Cisco/Cisco AnyConnect Secure Mobility Client"); 
writer.WriteElementString("folder", @"file:///C:/Arduino223"); 
writer.WriteEndElement(); 
//writer.WriteEndElement(); 
//writer.WriteEndDocument(); 
    writer.Flush(); 
    writer.Close();

無需重新創建文件追加新的數據，你可以這樣做：

XDocument doc = XDocument.Load(@"C:\Users\Alek\Dropbox\D\Debug\product.xml"); 
XElement school = doc.Element("root"); 
school.Add(new XElement("OFBM", 
        new XElement("folder", "file:///C:/Arduino223"))); 
doc.Save(@"C:\Users\Alek\Dropbox\D\Debug\product.xml");
