C#使用反射得到属性然后创建xml文档
一:通过实体对象生成xml文档
1.实体对象必须包含熟悉,且都是public类型,例如下面的person类
public class Person
{
public string Id { get; set; }
public string Name { get; set; }
public string Age { get; set; }
public string Sex { get; set; }
}
{
public string Id { get; set; }
public string Name { get; set; }
public string Age { get; set; }
public string Sex { get; set; }
}
2.通过反射获得熟悉名称,并且转换为小写,同时使用System.Xml命名空间的相关类创建xml文档
public static void CreateXmlByModel(List <object> list, string filename, string encode)
{
string root =null ;
if (list.Count > 0)
{
Type p = list[0].GetType();
root = p.Name.ToLower() +"s";
}
XmlDocument doc = new XmlDocument();
XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", encode, "yes");
doc.AppendChild(dec);
XmlElement rootElement = doc.CreateElement(root);
doc.AppendChild(rootElement);
//添加子节点
foreach( Object item in list)
{
XmlElement e = doc.CreateElement(item.GetType().Name.ToLower());
PropertyInfo[] pi = item.GetType().GetProperties();
int i = 0;
foreach ( PropertyInfo pro in pi)
{
XmlElement child = doc.CreateElement(pro.Name.ToLower());
child.InnerText = pro.GetValue(item, null).ToString();
e.AppendChild(child);
i++;
}
rootElement.AppendChild(e);
}
doc.Save(filename);
}
{
string root =null ;
if (list.Count > 0)
{
Type p = list[0].GetType();
root = p.Name.ToLower() +"s";
}
XmlDocument doc = new XmlDocument();
XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", encode, "yes");
doc.AppendChild(dec);
XmlElement rootElement = doc.CreateElement(root);
doc.AppendChild(rootElement);
//添加子节点
foreach( Object item in list)
{
XmlElement e = doc.CreateElement(item.GetType().Name.ToLower());
PropertyInfo[] pi = item.GetType().GetProperties();
int i = 0;
foreach ( PropertyInfo pro in pi)
{
XmlElement child = doc.CreateElement(pro.Name.ToLower());
child.InnerText = pro.GetValue(item, null).ToString();
e.AppendChild(child);
i++;
}
rootElement.AppendChild(e);
}
doc.Save(filename);
}
二:根据xml文档获得实体的集合(实体是跟上面对应的)
public static List<Person GetModelsFromXml( string file)
{
List<Person list = null;
if (File.Exists(file))
{
list = new List<Person();
//解析xml
XmlDocument doc = new XmlDocument();
doc.Load(file);
Type type = typeof(Person);
String root = type.Name.ToLower() + "s";
XmlNode rootNode = doc.SelectSingleNode(root);
XmlNodeList nodes = rootNode.ChildNodes;
foreach (XmlNode item in nodes)
{
Person person = new Person();
PropertyInfo[] pi = type.GetProperties();
XmlNodeList childs = item.ChildNodes;
//遍历子节点
for ( int i = 0; i < childs.Count; i++)
{
XmlNode n = childs[i];
//查找属性名称和xml文档中一致的节点名称,并且设置属性值
List ps = pi.Where(p => p.Name.ToLower() == n.Name).ToList ();
ps[0].SetValue(person, n.InnerText.ToString(), null);
}
list.Add(person);
}
}
return list;
{
List<Person list = null;
if (File.Exists(file))
{
list = new List<Person();
//解析xml
XmlDocument doc = new XmlDocument();
doc.Load(file);
Type type = typeof(Person);
String root = type.Name.ToLower() + "s";
XmlNode rootNode = doc.SelectSingleNode(root);
XmlNodeList nodes = rootNode.ChildNodes;
foreach (XmlNode item in nodes)
{
Person person = new Person();
PropertyInfo[] pi = type.GetProperties();
XmlNodeList childs = item.ChildNodes;
//遍历子节点
for ( int i = 0; i < childs.Count; i++)
{
XmlNode n = childs[i];
//查找属性名称和xml文档中一致的节点名称,并且设置属性值
List ps = pi.Where(p => p.Name.ToLower() == n.Name).ToList ();
ps[0].SetValue(person, n.InnerText.ToString(), null);
}
list.Add(person);
}
}
return list;
}
