问题描述

I am only trying to test connection with the redis server?我只是想测试与 redis 服务器的连接？ If all the connection configuration are correct and if I am able to establish a connection with the redis server using C#. Here is the code that I used:如果所有连接配置都正确，并且我能够使用 C# 与 redis 服务器建立连接。这是我使用的代码：

class Program
{
    static readonly ConnectionMultiplexer redis = ConnectionMultiplexer.Connect(
        new ConfigurationOptions
        {
            EndPoints = { "******windows.net", "6380" },
            Password = "****",
            Ssl = true,
            AbortOnConnectFail = false,
            AllowAdmin = true,
            ConnectTimeout = 30000,
            SyncTimeout = 30000
        });
        
    static async Task Main(string[] args)
    {
        ThreadPool.SetMinThreads(10, 10);
        var db = redis.GetDatabase();
        var pong = await db.PingAsync();
        Console.WriteLine(pong);
    }
}

Here is the error I am getting:这是我收到的错误：

StackExchange.Redis.RedisTimeoutException:

and it was not sent, command=PING,

What am I missing here with this code?这段代码我在这里错过了什么？

    EndPoints = { "******windows.net", "6380" },

should be应该

    EndPoints = { { "******windows.net", 6380 } },

or perhaps more simply:或者更简单地说：

    EndPoints = { "******windows.net:6380" },

Right now, you're connecting to "******windows.net" on 6379, and (separately, as a different endpoint) "6380" on 6379.现在，您正在连接到 6379 上的"******windows.net"和 6379 上的（分别作为不同端点） "6380" 。

Note that you will need to be able to reach the machine - it must resolve by DNS (or be specified as an IP address), be routable by you, and the designated port(s) must be open.请注意，您将需要能够访问该机器 - 它必须通过 DNS（或指定为 IP 地址）解析，可由您路由，并且指定的端口必须打开。
