我正在实现一个必须使用Java Web服务的c＃webservice客户端。通信协议是https，并且必须通过证书（包括私钥）进行身份验证。
据我所知，私钥的目的是识别Web服务背后的正确客户数据库。
我不知道证书文件的格式，因为它的文件扩展名是“txt”。如果我尝试通过mmc控制台在Windows证书存储区中导入此文件，则会出现“无法识别文件类型”的错误（我将其翻译为德语，因此英语听起来可能略有不同）。所以我的客户端应用程序无法使用它在证书库中找不到的证书。
我尝试实例化证书并将文件位置传递给构造函数。
mVerifyCert = new X509Certificate2(AppConfig.Settings.Default.CertificateAndKeyFileFullName);
但随后发生以下异常（英文版可能是“System.Security.Cryptography.CryptographicException：找不到对象。”
{System.Security.Cryptography.CryptographicException：Das angeforderte Objekt wurde nicht gefunden。
bei System.Security.Cryptography.CryptographicException.ThrowCryptogaphicException（Int32 hr） bei System.Security.Cryptography.X509Certificates.X509Utils._QueryCertFileType（String fileName） bei System.Security.Cryptography.X509Certificates.X509Certificate.LoadCertificateFromFile（String fileName，Object password，X509KeyStorageFlags keyStorageFlags） bei System.Security.Cryptography.X509Certificates.X509Certificate..ctor（String fileName） bei System.Security.Cryptography.X509Certificates.X509Certificate2..ctor（String fileName）
所以现在人们可能会认为该文件存在问题。但是当这个文件与SoapUI Tool一起使用来测试web服务时，它可以正常工作。 我也hava java示例客户端应用程序使用此文件与java信任存储区，它适用于Java客户端。
我还尝试将文件扩展名从“txt”更改为“p12”，“pem”，以便能够将文件导入Windows证书库，但没有成功。
你能告诉我这里的问题是什么吗？我该怎么做才能解决这个问题。我根本不知道。
这是我的app.config：
