I have a methodInfo from mymethod method of Example class.
internal class Example
{
public static void mymethod(string str1, ref string str2, out string str3)
{
....
MethodInfo mm = typeof(Example).GetMethod("mymethod");
How can I make an attribute (for example, ABCAttribute) of mm so that
mm.IsDefined(typeof(ABCAttribute), true)
becomes true?
You need to define your attribute.
Then apply it to your method.
