TypeloadExcepti on with static method

my problem is as follows:

abstract class A
{
abstract Foo();
static Doit()
{
A = new B();
}
}

class B : A
{
override Foo(){}
}

When I call B.DoIt(); a Typeloadexcepti on occurs.

I extremely simplified the problem here but you basically see what its going
on. In my little example here the TypeloadExcepti on doesn't occur (I cannot
reproduce it without my whole app). But I have to note that I have the
problem since I changed Foo() from virtual to abstract. When I change it
back it works fine.

Any ideas?

Hi.

I tried your code (I added some public modifiers) and it worked smoothly
with .NET SDK 1.1.

If you want I can send privately the C# source I used.

Have a nice day

Just thought I would contribute some knowledge for a change. After hours tracking down a problem with obfuscated code, where we were getting the exception : System.TypeLoadException: Method a on type b from assembly is overriding a method impl. We traced it to a class that implements multiple interfaces, two of which defined the same method, with same name and same signature. That is,

Hi All, I'm trying to create a generic node class for generating class hierarchies like XmlNode/XmlDocument.

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 Here is the code in...

Overview: 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,...
