C#获取XML文件内容的方式

首先设定有一个xml文件Configs.xml,其内容如下：

(资料图片)

一、读取外部的XML文件方法

//获取所有一级目录
List devices = new List();
XmlDocument doc = new XmlDocument();
doc.Load(AppDomain.CurrentDomain.BaseDirectory + @"\TEMP\Configs.xml");
XmlNode xnl1 = doc.DocumentElement;
foreach (XmlNode xn1 in xnl1.ChildNodes)
{
    XmlElement xe1 = (XmlElement)xn1;
    devices.Add(xe1.GetAttribute("name").ToString());
}
return devices;

//获取某个一级目录下的子目录
 List types = new List();
 XmlDocument doc = new XmlDocument();
 doc.Load(AppDomain.CurrentDomain.BaseDirectory + @"\TEMP\Configs.xml");
 XmlNode xnl1 = doc.DocumentElement;
 foreach (XmlNode xn1 in xnl1)
 {
     XmlElement xe1 = (XmlElement)xn1;
     if (xe1.GetAttribute("name").ToString() == "aaa")
     {
         XmlNodeList xnl2 = xe1.ChildNodes;
         foreach (XmlNode xn2 in xnl2)
         {
             XmlElement xe2 = (XmlElement)xn2;
             types.Add(xe2.GetAttribute("name").ToString());
         }
         break;
     }
 }
 return types;

二、读取内部XML文件方法

文件属性：

复制到输出目录：不复制

生成操作：嵌入的资源

//获取所有一级目录
List devices = new List();         
string config= System.Reflection.Assembly.GetExecutingAssembly().GetName().Name + ".Configs.Configs.xml";
System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.IO.Stream s = assembly.GetManifestResourceStream(config);

XmlReaderSettings settings = new XmlReaderSettings();
settings.IgnoreComments = true;
XmlReader reader = XmlReader.Create(s, settings);
XmlDocument doc = new XmlDocument();

doc.Load(reader);
XmlNode xn = doc.SelectSingleNode("Config");
XmlNodeList xnl1 = xn.ChildNodes;
foreach (XmlNode xn1 in xnl1)
{
    XmlElement xe1 = (XmlElement)xn1;
    devices.Add(xe1.GetAttribute("name").ToString());
}
reader.Close();
return devices;

//获取某个一级目录下的子目录
List types = new List();           
string config= System.Reflection.Assembly.GetExecutingAssembly().GetName().Name + ".Configs.Configs.xml";
System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.IO.Stream s = assembly.GetManifestResourceStream(config);

XmlReaderSettings settings = new XmlReaderSettings();
settings.IgnoreComments = true;
XmlReader reader = XmlReader.Create(s, settings);
XmlDocument doc = new XmlDocument();

doc.Load(reader);
XmlNode xn = doc.SelectSingleNode("Config");
XmlNodeList xnl1 = xn.ChildNodes;
foreach (XmlNode xn1 in xnl1)
{
    XmlElement xe1 = (XmlElement)xn1;
    if (xe1.GetAttribute("name").ToString() == "aaa")
    {
        XmlNodeList xnl2 = xe1.ChildNodes;
        foreach (XmlNode xn2 in xnl2)
        {
            XmlElement xe2 = (XmlElement)xn2;
            types.Add(xe2.GetAttribute("name").ToString());
        }
        break;
    }
}
reader.Close();
return types;

三、读取类库中XML文件的方法

文件属性：

复制到输出目录：不复制

生成操作：Resource

List types = new List();
string fileName = AppDomain.CurrentDomain.BaseDirectory + "Config.dll";
System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFile(fileName);
string resourceName = assembly.GetName().Name + ".g";
System.Resources.ResourceManager manager = new System.Resources.ResourceManager(resourceName, assembly);
object obj = manager.GetObject("asserts/config.xml");//全部字母小写
System.IO.Stream stream = (System.IO.Stream)obj;

XmlDocument doc = new XmlDocument();
XmlReaderSettings settings = new XmlReaderSettings();
settings.IgnoreComments = true;//忽略文档里面的注释，因为在没有特别说明的情况下，注释也是一个节点
XmlReader reader = XmlReader.Create(stream, settings);

doc.Load(reader);
XmlNode xn = doc.SelectSingleNode("Config");
XmlNodeList xnl1 = xn.ChildNodes;

foreach (XmlNode xn1 in xnl1)
{
    XmlElement xe1 = (XmlElement)xn1;
    Type type = new Type();
    type.name = xe1.GetAttribute("name").ToString();
    type.func = xe1.GetAttribute("func").ToString();
    XmlNodeList xnl0 = xe1.ChildNodes;
    type.Content = xnl0.Item(0).InnerText.Substring(1).TrimEnd();
    types.Add(type);
}
reader.Close();
return types;

四、读取程序内添加的外部可见的XML文件

文件属性：

复制到输出目录：始终复制

生成操作：内容

List devices= new List();
XmlDocument doc = new XmlDocument();
XmlReaderSettings settings = new XmlReaderSettings();
settings.IgnoreComments = true;
XmlReader reader = XmlReader.Create(@"Asserts\Config.xml", settings);

doc.Load(reader);
XmlNode xn = doc.SelectSingleNode("Config");
XmlNodeList xnl1 = xn.ChildNodes;

foreach (XmlNode xn1 in xnl1)
{
    XmlElement xe1 = (XmlElement)xn1;
    devices.Add(xe1.GetAttribute("name").ToString());
}
reader.Close();
return serialsList;
