从自定义属性访问父类

[MyCustomAttribute(typeof(MyClass))]
public class MyClass {
  ///
}

使用上面的反射解决方案,您实际上并没有实现从属性获取类型的操作,相反,您正在从类型获取属性。此时,您已经拥有了类型。

你可以通过反射来实现。在你的主课上做以下练习:

Type type = typeof(ExampleDropDownViewModel));
// Get properties of your data class
PropertyInfo[] propertyInfo = type.GetProperties( );

foreach( PropertyInfo prop in propertyInfo )
{
   // Fetch custom attributes applied to a property        
   object[] attributes = prop.GetCustomAttributes(true);

   foreach (Attribute attribute in attributes) {
      // we are only interested in DropDownList Attributes..
      if (attribute is DropDownListAttribute) {
    DropDownListAttribute dropdownAttrib = (DropDownListAttribute)attribute;
         Console.WriteLine("table set in attribute: " + dropdownAttrib.myTable);
      }
   }
}
