13.11. Hot Rod C# Client
The Hot Rod C# client is a new addition to the list of Hot Rod clients that includes Hot Rod Java and Hot Rod C++ clients. Hot Rod C# client allows .NET runtime applications to connect and interact with Red Hat JBoss Data Grid servers.
The Hot Rod C# 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 32-bit and 64-bit operating systems on which the .NET Framework is supported by Microsoft. The .NET Framework 4.0 is a prerequisite along with the supported operating systems to use the Hot Rod C# client.
Warning
The Hot Rod C# client is a Technology Preview feature and is not supported in JBoss Data Grid 6.3.

13.11.2. Hot Rod C# Client Configuration
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 13.8. 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; 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); [...] } } }
13.11.3. 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 13.9.
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(); } } }
