在C#中實現分布式哈希(DHT)可以使用Kademlia算法或Chord算法
Install-Package Akka
using Akka;
using Akka.Actor;
namespace DhtExample
{
class Program
{
static void Main(string[] args)
{
ActorSystem system = ActorSystem.Create("DhtSystem");
// ...
}
}
}
public class DhtNode : ReceiveActor
{
private readonly Dictionary<string, string> _data = new Dictionary<string, string>();
public DhtNode()
{
Receive<StoreMessage>(msg => Store(msg));
Receive<LookupMessage>(msg => Lookup(msg));
Receive<DeleteMessage>(msg => Delete(msg));
}
private void Store(StoreMessage msg)
{
_data[msg.Key] = msg.Value;
Sender.Tell(new StoreSuccessMessage());
}
private void Lookup(LookupMessage msg)
{
if (_data.ContainsKey(msg.Key))
{
Sender.Tell(new LookupSuccessMessage(_data[msg.Key]));
}
else
{
Sender.Tell(new LookupFailureMessage());
}
}
private void Delete(DeleteMessage msg)
{
if (_data.Remove(msg.Key))
{
Sender.Tell(new DeleteSuccessMessage());
}
else
{
Sender.Tell(new DeleteFailureMessage());
}
}
}
public class StoreMessage
{
public string Key { get; }
public string Value { get; }
public StoreMessage(string key, string value)
{
Key = key;
Value = value;
}
}
public class LookupMessage
{
public string Key { get; }
public LookupMessage(string key)
{
Key = key;
}
}
public class DeleteMessage
{
public string Key { get; }
public DeleteMessage(string key)
{
Key = key;
}
}
// 其他消息類,如成功和失敗的響應
// ...
IActorRef node1 = system.ActorOf<DhtNode>("node1");
IActorRef node2 = system.ActorOf<DhtNode>("node2");
// ...
node1.Tell(new StoreMessage("key1", "value1"));
node2.Tell(new LookupMessage("key1"));
node1.Tell(new DeleteMessage("key1"));
這只是一個簡單的示例,實際上你需要實現更復雜的邏輯來處理節點之間的通信、數據分區和故障恢復等。你可以參考現有的開源項目,如AElf和Orleans,以獲取更多關于如何在C#中實現分布式哈希的信息。
