我不完全确定你实际上在问什么，但是...

I am not completely sure about what are you actually asking, but...

如果要为客户端使用自签名证书，则需要使用以下方法手动验证该证书:ServicePointManager.ServerCertificateValidationCallback

If you want to use a self-signed certificate for the client, you need to validate that certificate manually using : ServicePointManager.ServerCertificateValidationCallback

为了测试，你可以这样做:

For the sake of testing, you can do:

ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

但是在进入生产环境时，您应该删除此代码或输入实际的认证验证代码.

But when moving to production you should remove this code or put an actual certification validation code.
