In our previous post, “Getting the Version of Redis Connected in C# & .NET”, we looked at how to get the version of the Redis instance we are connected to using the StackExchange.Redis package.

The caveat was that we needed to connect with admin access to call the INFO method natively in the library.

In this post, we will explore how to achieve the same result without requiring admin access.

Since we cannot natively call the Info method of the Server object, we need to change our approach slightly.

We can call the Execute method of the Database object and use that to directly run the INFO command.

This returns a long string with all of the configuration information as follows:

# Server
redis_version:8.2.1
redis_git_sha1:00000000
redis_git_dirty:1
redis_build_id:4b18c1051be99449
redis_mode:standalone
os:Linux 6.15.11-orbstack-00539-g9885ebd8e3f4 aarch64
arch_bits:64
monotonic_clock:POSIX clock_gettime
multiplexing_api:epoll
atomicvar_api:c11-builtin
gcc_version:14.2.0
process_id:1
process_supervised:no
run_id:ff81c0441db056dc6d5902e4fac09a3b32e29cdd
tcp_port:6379
server_time_usec:1757148739172274
uptime_in_seconds:395229
uptime_in_days:4
hz:10
configured_hz:10
lru_clock:12318275
executable:/data/redis-server
config_file:
io_threads_active:0
listener0:name=tcp,bind=*,bind=-::*,port=6379

From this, we can extract the line we want, which starts with redis_version.

One way to approach this is to extract the large string into a Dictionary, which will be easier to examine and query.

The code will look something like this:

using StackExchange.Redis;

// Connect to Redis instance
await using var connection =
    await ConnectionMultiplexer.ConnectAsync("localhost:6379,password=YourStrongPassword123");

var db = connection.GetDatabase();

// Run INFO Server command, casting result into a string
var result = (string)(await db.ExecuteAsync("INFO", "Server"))!;

// Extract the elements into a dictionary
var info = result.Split(Environment.NewLine, StringSplitOptions.RemoveEmptyEntries)
    .Where(line => line.Contains(':')) // only consider attribute lines 
    .Select(line => line.Split(':')) // project into attribute-value
    .ToDictionary(parts => parts[0], parts => parts[1]); // Convert to dictionary

// Fetch the value from the dictionary
Console.WriteLine(info["redis_version"]);

In the debugger, the info data structure looks like this, showing all the captured server configurations:

redisInfo

The code will print something like this to the console:

8.2.1

TLDR

You can directly execute the INFO command against the Database object to retrieve Redis configurations.

The code is in my GitHub.

Happy hacking!
