C#学习教程：使用C#.Net通过FTPS(SSL/TLS)传输文件现在它通过常规FTP连接，但现在我们的IT人员希望通过安全的FTPS连接来设置它。他们为我提供了一个*.cr_certificate文件。如果我在记事本中打开该文件，我会看到类似这样的内容（但真正的密钥显然不是foobar）。-----BEGINRSAPRIVATEFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBAR-----ENDRSAPRIVATEKEY----------BEGINCERTIFICATE-----FOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBAR-----ENDCERTIFICATE-----如何使用此证书文件连接到FTPS服务器以上载和下载文件？Forgiveme,butI'mnewtoanythingthatinvolvestransferringfilesoveranetwork,安全连接、证书、公钥、私钥等等......等等......我想我想使用FtpWebRequest对象并将EnableSsl属性设置为true但我不确定这个证书文件在哪里发挥作用。如果您使用的是FtpWebRequest类，只需向您的请求设置中添加一些内容即可。请务必包括使用System.Security.Cryptography.X509Certificates；陈述。FtpWebRequest请求=(FtpWebRequest)WebRequest.Create(ftpUrl);request.Credentials=newNetworkCredential(用户名,密码);request.EnableSsl=true;//ServicePointManager.ServerCertificateValidationCallback=ServicePointManager_ServerCertificateValidationCallback;X509Certificatecert=X509Certificate.CreateFromCertFile(@"C:MyCertDirMyCertFile.cer");X509CertificateCollectioncertCollection=newX509CertificateCollection();certCollection.Add（证书）；request.ClientCertificates=certCollection;此外，如果您遇到证书生成异常问题，您可能希望实现自己的证书验证回调方法，以与ServicePointManager.ServerCertificateValidationCallback属性一起使用。这可以像总是返回true一样简单，也可以像我用来调试那样复杂：if(sslPolicyErrors!=SslPolicyErrors.None){Console.WriteLine("正在接受有错误的证书：");if((sslPolicyErrors&SslPolicyErrors.RemoteCertificateNameMismatch)==SslPolicyErrors.RemoteCertificateNameMismatch){Console.WriteLine("t证书主题{0}不匹配。",certificate.Subject);}if((sslPolicyErrors&SslPolicyErrors.RemoteCertificateChainErrors)==SslPolicyErrors.RemoteCertificateChainErrors){Console.WriteLine("t证书链有以下错误：");foreach(X509ChainStatuschainStatusinchain.ChainStatus){Console.WriteLine("tt{0}",chainStatus.StatusInformation);如果（chainStatus.Status==X509ChainStatusFlags.Revoked）{allowCertificate=false;}}}if((sslPolicyErrors&SslPolicyErrors.RemoteCertificateNotAvailable)==SslPolicyErrors.RemoteCertificateNotAvailable){Console.WriteLine("没有可用的证书。");允许证书=假；}控制台.WriteLine();代码解释了如何做到这一点本文的目的是在安全模式下创建一个C#FTP客户端，所以如果您对FTPS了解不多，我建议您看一下这个：FTPS。在.NETFramework中，通过FTPS方式上传文件，我们通常使用FtpWebRequest类，但是不能发送带有quote参数的命令，即使在网上搜索，也找不到安全的C#FTP的具体例子客户。由于这些原因，我决定创建这篇文章。以上就是C#学习教程的全部内容：使用C#.Net通过FTPS（SSL/TLS）传输文件，不代表立场，如涉及侵权，请点击右侧联系管理员删除。如需转载请注明出处：
