本文介绍了C# 覆盖子类中的属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
public class MyWebControl {
[ExternallyVisible]
public string StyleString {get;set;}
}
public class SmarterWebControl : MyWebControl {
[ExternallyVisible]
public string CssName{get;set;}
new public string StyleString {get;set;} //Doesn't work
}
是否可以删除子类中的属性?我确实希望该属性被其他子类继承，而不是这个.
Is it possible to remove the attribute in the subclass? I do want the attribute to get inherited by other subclasses, just not this one.
哎呀，好像我忘了编译什么的，因为上面发布的代码确实有效！
Whoops, looks like I forgot to compile or something because the code as posted above does, in fact, work!
推荐答案
它对我有用.
测试代码:
public static void Main()
{
var attribute = GetAttribute(typeof (MyWebControl), "StyleString", false);
Debug.Assert(attribute != null);
attribute = GetAttribute(typeof(SmarterWebControl), "StyleString", false);
Debug.Assert(attribute == null);
attribute = GetAttribute(typeof(SmarterWebControl), "StyleString", true);
Debug.Assert(attribute == null);
}
private static ExternallyVisibleAttribute GetAttribute(Type type, string propertyName, bool inherit)
{
PropertyInfo property = type.GetProperties().Where(p=>p.Name.Equals(propertyName, StringComparison.OrdinalIgnoreCase)).FirstOrDefault();
var list = property.GetCustomAttributes(typeof(ExternallyVisibleAttribute), inherit).Select(o => (ExternallyVisibleAttribute)o);
return list.FirstOrDefault();
}
