Couldn't find class in assembly

[redleaf1221]

With code snippet looks like this:

const assembly = Il2Cpp.domain.assembly("Assembly-CSharp").image;
assembly.class('a.CryptUtils').method('Verify').implementation = () => {return true;};
assembly.class('a.Network.Certificate.Validator').method('Check').implementation = () => {return true;};

It gives me an error:
couldn't find class a.Network.Certificate.Validator in assembly Assembly-CSharp.dll

My dump from Il2Cpp.dump() looks like this:

// Assembly-CSharp
class a.CryptUtils : System.Object
{
    static System.Boolean Verify(......);
}
// a.Common
interface a.Network.Certificate.CertificateHandlerFactory.InterfaceValidator : 
{
    System.Boolean Check(......);
}
// a.Common
class a.Network.Certificate.Validator : System.Object, a.Network.Certificate.CertificateHandlerFactory.InterfaceValidator
{
    System.Boolean Check(......);
}

Would you try the following:

assembly.class('a.Network').nested('Validator').method('Check').implementation = () => {return true;};

Sorry for my inexperience.
Fora.Network.Certificate.Validator::Check,I tried:

assembly.class('a.Network').nested("Certificate.Validator").method('Check')

assembly.class('a.Network.Certificate').nested("Validator").method('Check')

assembly.class('a.Network').nested("Certificate").nested("Validator").method('Check')

But they don't work.
I was confused that a.Network.Certificate.Validator is marked with a.Common, is that a problem?

Oh, yeah you are right. a.Common is the name of the assembly, so:

const Common = Il2Cpp.domain.assembly("a.Common").image;

then use Common instead of assembly

Itt worked, thank you.
