I have created an Attribute, call MyAttribute, which is performing some security and for some reason the Constructor is not being fired, any reason why?
public class Driver
{
// Entry point of the program
public static void Main(string[] Args)
{
Console.WriteLine(SayHello1("Hello to Me 1"));
Console.WriteLine(SayHello2("Hello to Me 2"));
Console.ReadLine();
}
[MyAttribute("hello")]
public static string SayHello1(string str)
{
return str;
}
[MyAttribute("Wrong Key, should fail")]
public static string SayHello2(string str)
{
return str;
}
}
[AttributeUsage(AttributeTargets.Method)]
public class MyAttribute : Attribute
{
public MyAttribute(string VRegKey)
{
if (VRegKey == "hello")
{
Console.WriteLine("Aha! You're Registered");
}
else
{
throw new Exception("Oho! You're not Registered");
};
}
}
