问题描述
我需要能够从我的方法中读取我的属性值,我该怎么做?
I need to be able to read the value of my attribute from within my Method, how can I do that?
[MyAttribute("Hello World")]
public void MyMethod()
{
// Need to read the MyAttribute attribute and get its value
}
推荐答案
你需要调用MethodBase 对象上的 noreferrer">GetCustomAttributes
函数.
获取 MethodBase
对象的最简单方法是调用 MethodBase.GetCurrentMethod
.(注意要加上[MethodImpl(MethodImplOptions.NoInlining)]
)
You need to call the GetCustomAttributes
function on a MethodBase
object.
The simplest way to get the MethodBase
object is to call MethodBase.GetCurrentMethod
. (Note that you should add [MethodImpl(MethodImplOptions.NoInlining)]
)
例如:
MethodBase method = MethodBase.GetCurrentMethod();
MyAttribute attr = (MyAttribute)method.GetCustomAttributes(typeof(MyAttribute), true)[0] ;
string value = attr.Value; //Assumes that MyAttribute has a property called Value
你也可以手动获取MethodBase
,像这样:(这样会更快)
You can also get the MethodBase
manually, like this: (This will be faster)
MethodBase method = typeof(MyClass).GetMethod("MyMethod");
