When are method attributes evaluated?

问题

[CustomMethodAttribute]
public void MyMethod(string[] args)
{
    // Some implementation
}

When will CustomMethodAttribute be evaluated and can you do anything to change when this evaluation takes place? Also, care to explain exactly how the compiler manages this trick?

In general, there is no evaluation that takes place. A custom attribute is added to the method as metadata, and available to be inspected via reflection at runtime as needed.

For details, see Attributes on MSDN.
