I have trouble to use "Is" operator to a type that is from reflection.
Basically, here is what I want to do, if Class1 type is not from reflection:
class Class1
{
}
public class Test
{
...
if (o is Class1) //to determine if object o is Class1, or is derivative
class of Class1
{
//object o can be cast to type
}
}
Now, Class1 is in different assembly, then I want to the samething, except
getting the Type from reflection
public class Test
{
...
Assembly objAssembly = Assembly.Load(" MyDll");
Type t = objAssembly.Get Type("MyDll.Cla ss1");
//How to determine if object o is Class1, or is derivative class of Class1
????????
//if (o is Class1)
}
Thank a lot for your kind response 4 1675
You should use the IsAssignableFro m() method of the Type class, like
this:
Assembly objAssembly = Assembly.Load(" MyDll");
Type t = objAssembly.Get Type("MyDll.Cla ss1");
if (t.IsAssignable From(o))
{
... etc ...
}
I think that's the way it goes... I always get that IsAssignableFro m
thing backward. :) Anyway, I believe that's the method you want to
call. You can't use the "is" operator directly.
>Now, Class1 is in different assembly, then I want to the samething, except getting the Type from reflection
I think you're looking for typeof(Class1). IsAssignableFro m(t);

Is there an advantage to either of these methods, or is it simply a matter
of style? I used to use the "as" method, but later gave it up for the "is"
method as the intent of the code seems a little clearer to me. I now have
some projects coming up where the baseTypeCollection will contain 5k to 10k
objects that will have to be searched for various sub types of which I only
expect to find ~50 to ~100 matches. Thanks!

Hello all;
Since I do have working code, this is more for my curiosity only.
I'm creating a "Plugin" architecture, following some of the many examples on
the 'net. Basically what I have is this:

(IPlugin). This DLL also contains a class with the ability to search for
DLLs in the calling applications working directory that contain classes
implementing IPlugin (I...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
