我在.NET Framework c上创建了一个工作客户端，并在本地主机上的.NET Core上安装了服务器:

I made a working client on the .NET Framework c with a server on .NET Core on localhost:

static async Task Main(string[] args)
{    
    string s = GetRootCertificates();
    var channel_creds = new SslCredentials(s);
    var channel = new Channel("localhost",50051, channel_creds);
    var client = new Informer.InformerClient(channel);
    await GetPing(client);
}

public static string GetRootCertificates()
{
    StringBuilder builder = new StringBuilder();
    X509Store store = new X509Store(StoreName.Root);
    store.Open(OpenFlags.ReadOnly);
    foreach (X509Certificate2 mCert in store.Certificates)
    {
        builder.AppendLine(
            "# Issuer: " + mCert.Issuer.ToString() + "\n" +
            "# Subject: " + mCert.Subject.ToString() + "\n" +
            "# Label: " + mCert.FriendlyName.ToString() + "\n" +
            "# Serial: " + mCert.SerialNumber.ToString() + "\n" +
            "# SHA1 Fingerprint: " + mCert.GetCertHashString().ToString() + "\n" +
            ExportToPEM(mCert) + "\n");
    }
    return builder.ToString();
}

/// <summary>
/// Export a certificate to a PEM format string
/// </summary>
/// <param name="cert">The certificate to export</param>
/// <returns>A PEM encoded string</returns>
public static string ExportToPEM(X509Certificate cert)
{
    StringBuilder builder = new StringBuilder();            

    builder.AppendLine("-----BEGIN CERTIFICATE-----");
    builder.AppendLine(Convert.ToBase64String(cert.Export(X509ContentType.Cert), Base64FormattingOptions.InsertLineBreaks));
    builder.AppendLine("-----END CERTIFICATE-----");

    return builder.ToString();
}

private static async Task GetPing(Informer.InformerClient client)
{
    Console.WriteLine("Getting ping...");
    try
    {
        Metadata headers = null;
        var response = await client.GetServerPingAsync(new Empty(), headers);
        string result = "Nan";
        if (response.PingResponse_ == 1)
            result = "Ok!";
        Console.WriteLine($"Ping say: {result }");
    }
    catch (Exception ex)
    {
        Console.WriteLine("Error get server ping." + Environment.NewLine + ex.ToString());
    }
}

但是我尚未在远程计算机上成功完成此工作(例如，其中ip 192.168.1.7是服务器地址，而客户端地址是192.168.1.2)

But I have not yet succeeded in making this work on remote machines (for example, where ip 192.168.1.7 is the server address and the client address is 192.168.1.2)
