XmlElement reflect

本文关键字:reflect XmlElement | 更新日期: 2023-09-27 17:56:23

像这两个类

[XmlRoot("Root")]
public class VcRead
{
    [XmlElement("item")]
    public string[] Items;
    [XmlElement("amount")]
    public int Count;
}
public class KeyItem
{
    [XmlAttribute("id")]
    public int ID;
    [XmlAttribute("name")]
    public string Title;
}

现在,我想使用反射来获取所有字段及其 Xml 标记。获取字段的名称及其值很容易。但是,如何获取 XmlElement 的值,例如"金额"

[XmlElement("amount")]
public int Count;

XmlElement reflect

Type type = typeof(VcRead);
foreach (var fiedInfo in type.GetFields())
{
    // your field
    foreach (var attribute in fiedInfo.GetCustomAttributes(true))
    {
        // attributes
    }                   
}

要从XmlElementAttribute获取元素名称(与XmlAttributeAttribute的方法相同):

if (attribute is XmlElementAttribute)
{
    var elementName = ((XmlElementAttribute)attribute).ElementName;
}

另请记住,您的类具有公共字段而不是属性。

而不是 XmlElement,使用 XmlElementAttribute,如下所示

[XmlElementAttribute("test")]
 public string Test  {get;set;};

然后,通过反射访问此对象的 GetProperties()

 PropertyInfo[] methods = typeof(KeyItem).GetProperties();

 foreach (PropertyInfo method in methods)
 {
  // Use of Attribute.GetCustomAttributes which you can access the attributes
    Attribute[] attribs = Attribute.GetCustomAttributes(method, typeof(XmlAttribute));
 }
