问题描述
我已经创建了类似
[AttributeUsage(AttributeTargets.Class, AllowMultiple = true)]
[Serializable]
public class TestPropertyAttribute : System.Attribute
{
public string Name
{
get { return _name; }
set { _name = value; }
}string _name;
}
我应该将名称"标记为该属性的强制属性.怎么做?
and I should mark "Name" as mandatory property of this attribute. How to do it?
推荐答案
把它放在构造函数中,而不是仅仅作为一个单独的属性:
Put it in the constructor instead of just as a separate property:
[AttributeUsage(AttributeTargets.Class, AllowMultiple = true)]
[Serializable]
public class TestPropertyAttribute : System.Attribute
{
readonly string _name;
public TestPropertyAttribute(string name)
{
_name = name;
}
public string Name { get { return _name; } }
}
我不相信你可以强制并且在应用属性时使用 Name=...
语法.
I don't believe you can make it mandatory and use the Name=...
syntax when applying the attribute though.
