11.8. Hot Rod C# Client

The Hot Rod C# client allows .NET runtime applications to connect and interact with Red Hat JBoss Data Grid servers. This client is aware of the cluster topology and hashing scheme, and can access an entry on the server in a single hop similar to the Hot Rod Java and Hot Rod C++ clients.

The Hot Rod C# client is compatible with 64-bit operating systems on which the .NET Framework is supported by Microsoft. The .NET Framework 4.5 is a prerequisite along with the supported operating systems to use the Hot Rod C# client.

11.8.2. Hot Rod C# Client Configuration
Copier lien

The Hot Rod C# client is configured programmatically using the ConfigurationBuilder. Configure the host and the port to which the client should connect.

Sample C# file configuration

The following example shows how to use the ConfigurationBuilder to configure a RemoteCacheManager.

Example 11.9. C# configuration

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Infinispan.HotRod;
using Infinispan.HotRod.Config;

            builder.AddServer()
                .Host(args.Length > 1 ? args[0] : "127.0.0.1")
                .Port(args.Length > 2 ? int.Parse(args[1]) : 11222);
            Configuration config = builder.Build();
            RemoteCacheManager cacheManager = new RemoteCacheManager(config);
            [...]
        }
    }

11.8.3. Hot Rod C# Client API

The RemoteCacheManager is a starting point to obtain a reference to a RemoteCache.

The following example shows retrieval of a default cache from the server and a few basic operations.

Example 11.10.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Infinispan.HotRod;
using Infinispan.HotRod.Config;
namespace simpleapp
{
    class Program
    {
        static void Main(string[] args)
        {
            ConfigurationBuilder builder = new ConfigurationBuilder();
            builder.AddServer()
                .Host(args.Length > 1 ? args[0] : "127.0.0.1")
                .Port(args.Length > 2 ? int.Parse(args[1]) : 11222);
            Configuration config = builder.Build();
            RemoteCacheManager cacheManager = new RemoteCacheManager(config);
            cacheManager.Start();
            // Retrieve a reference to the default cache.
            IRemoteCache<String, String> cache = cacheManager.GetCache<String, String>();
            // Add entries.
            cache.Put("key1", "value1");
            cache.PutIfAbsent("key1", "anotherValue1");
            cache.PutIfAbsent("key2", "value2");
            cache.PutIfAbsent("key3", "value3");
            // Retrive entries.
            Console.WriteLine("key1 -> " + cache.Get("key1"));
            // Bulk retrieve key/value pairs.
            int limit = 10;
            IDictionary<String, String> result = cache.GetBulk(limit);
            foreach (KeyValuePair<String, String> kv in result)
            {
                Console.WriteLine(kv.Key + " -> " + kv.Value);
            }
            // Remove entries.
            cache.Remove("key2");
            Console.WriteLine("key2 -> " + cache.Get("key2"));
            cacheManager.Stop();

11.8.4. String Marshaller for Interoperability
Copier lien

To use the string compatibility marshaller, pass an instance of CompatibilityMarshaller to the Marshaller() method of the ConfigurationBuilder object similar to this:

ConfigurationBuilder builder = new ConfigurationBuilder();
builder.Marshaller(new CompatibilityMarshaller());
RemoteCacheManager cacheManager = new RemoteCacheManager(builder.build(), true);
IRemoteCache<String, String> cache = cacheManager.GetCache<String, String>();
[....]
cache.Put("key", "value");
[...]
cache.Get("key");
[...]

ConfigurationBuilder builder = new ConfigurationBuilder();
builder.Marshaller(new CompatibilityMarshaller());
RemoteCacheManager cacheManager = new RemoteCacheManager(builder.build(), true);
IRemoteCache<String, String> cache = cacheManager.GetCache<String, String>();
[....]
cache.Put("key", "value");
[...]
cache.Get("key");
[...]

Attempts to store or retrieve non-string key/values will result in a HotRodClientException being thrown.
