我需要能够从我的方法看我的属性值,我该怎么办呢?
[MyAttribute(的Hello World)
公众诠释的MyMethod()
{
//需要阅读MyAttribute属性并获得其值
}
解决方案
您需要调用 GetCustomAttributes
一个 MethodBase
对象上的功能。
获得最简单的方式 MethodBase
对象是调用MethodBase.GetCurrentMethod. (请注意,您应该添加 [MethodImpl(MethodImplOptions.NoInlining)]
)
例如:
MethodBase方法= MethodBase.GetCurrentMethod();
MyAttribute ATTR =(MyAttribute)method.GetCustomAttributes(typeof运算(MyAttribute),真)[0];
字符串值= attr.Value; //假设条件是MyAttribute有一个叫做财产价值
您还可以得到 MethodBase
手动,像这样:(这将是更快)
MethodBase方法= typeof运算(MyClass的).GetMethod(的MyMethod);
I need to be able to read the value of my attribute from within my Method, how can I do it?
[MyAttribute("Hello World")]
public int MyMethod()
{
//Need to read the MyAttribute attribute and get its value
}
解决方案
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)]
)
For example:
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
You can also get the MethodBase
manually, like this: (This will be faster)
MethodBase method = typeof(MyClass).GetMethod("MyMethod");
