微信支付证书 系统找不到指定的文件

System.Security.Cryptography.CryptographicException: 系统找不到指定的文件。

将微信Post里面读取证书的方法如下:

    X509Certificate2 cert = new X509Certificate2(path + WxPayConfig.SSLCERT_PATH, WxPayConfig.SSLCERT_PASSWORD);
    request.ClientCertificates.Add(cert);

修改成如下：
                    X509Certificate2 cert = new X509Certificate2(path + WxPayConfig.SSLCERT_PATH, WxPayConfig.SSLCERT_PASSWORD, X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.MachineKeySet);
                    request.ClientCertificates.Add(cert);
