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：
<?xml version="1.0" encoding="utf-8" ?>
<Config>
<Device name="aaa">
<Type name="a01" func="1"></Type>
<Type name="a02"></Type>
<Type name="a03"></Type>
<Type name="a04"></Type>
</Device>
<Device name="bbb">
<Type name="b01"></Type>
<Type name="b02"></Type>
<Type name="b03"></Type>
<Type name="b04"></Type>
</Device>
<Device name="ccc">
<Type name="c01"></Type>
<Type name="c02"></Type>
<Type name="c03"></Type>
<Type name="c04" func="2"></Type>
</Device>
</Config>一、读取外部的XML文件方法
//获取所有一级目录
List<string> devices = new List<string>();
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<string> types = new List<string>();
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<string> devices = new List<string>();
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<string> types = new List<string>();
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<Type> types = new List<Type>();
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<string> devices= new List<string>();
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;总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
