您确定您在属性中指定了正确的公钥吗?请注意，您需要指定完整的公钥，而不仅仅是公钥令牌.它看起来像:

Are you absolutely sure you have the correct public key specified in the attribute? Note that you need to specify the full public key, not just the public key token. It looks something like:

[assembly: InternalsVisibleTo("MyFriendAssembly,
PublicKey=0024000004800000940000000602000000240000525341310004000001000100F73

6E2F553073FF557D2DB6C5")]

它是 320 个左右的十六进制数字.不确定为什么需要指定完整的公钥 - 可能只使用在其他程序集引用中使用的公钥令牌，这样有人会更容易欺骗朋友程序集的身份.

It's 320 or so hex digits. Not sure why you need to specify the full public key - possibly with just the public key token that is used in other assembly references it would be easier for someone to spoof the friend assembly's identity.
