EonaCat.JASP
### Basic TCP Server
```csharp
using EonaCat.JASP;
var server = new NetworkServer(ProtocolType.TCP, 5000);
server.DataReceived += (s, e) =>
{
var message = Encoding.UTF8.GetString(e.Data);
Console.WriteLine($"Received: {message}");
};
server.Start();
```
### Basic TCP Client
```csharp
var client = new NetworkClient(ProtocolType.TCP, "127.0.0.1", 5000);
client.DataReceived += (s, e) =>
{
var message = Encoding.UTF8.GetString(e.Data);
Console.WriteLine($"Received: {message}");
};
await client.ConnectAsync();
client.SendString("Hello, Server!");
```
## Advanced
### Server with Authentication
```csharp
var server = new NetworkServer(
ProtocolType.TCP,
5000,
username: "ServerAdmin",
password: "SecurePassword123"
);
server.ClientConnected += (s, e) =>
{
Console.WriteLine($"Authenticated client: {e.Username}");
};
server.Start();
```
### Client with Authentication
```csharp
var client = new NetworkClient(
ProtocolType.TCP,
"127.0.0.1",
5000,
username: "Alice",
password: "SecurePassword123"
);
await client.ConnectAsync();
```
### Server with AES Encryption
```csharp
var server = new NetworkServer(
ProtocolType.TCP,
5000,
useAES: true
);
server.Start();
```
### Client with AES Encryption
```csharp
var client = new NetworkClient(
ProtocolType.TCP,
"127.0.0.1",
5000,
useAES: true
);
await client.ConnectAsync();
```
### UDP Server/Client
```csharp
// Server
var server = new NetworkServer(ProtocolType.UDP, 5000);
server.Start();
// Client
var client = new NetworkClient(ProtocolType.UDP, "127.0.0.1", 5000);
await client.ConnectAsync();
```
### Client-to-Client Messaging
```csharp
// On Client 1 (Alice)
alice.SendToClient("Bob", "Hi Bob!");
// On Client 2 (Bob)
bob.DataReceived += (s, e) =>
{
if (e.FromUsername == "Alice")
{
Console.WriteLine($"Message from Alice: {Encoding.UTF8.GetString(e.Data)}");
}
};
```
### Broadcasting to All Clients
```csharp
// Server broadcasts to all connected clients
server.BroadcastString("Server announcement!");
// Broadcast to all except one client
server.BroadcastString("Message", excludeUsername: "Alice");
```
### Send Binary Data
```csharp
// Send byte array
byte[] imageData = File.ReadAllBytes("image.jpg");
client.SendData(imageData);
// Send to specific client
client.SendToClient("Bob", imageData);
```
### Network Statistics
```csharp
// Get server stats
var serverStats = server.GetStats();
Console.WriteLine(serverStats);
// Output:
// Stats:
// Uptime: 00:05:23
// Messages Sent: 15,234
// Messages Received: 15,234
// Bytes Sent: 1,523,400
// Bytes Received: 1,523,400
// Active Connections: 5
// Messages/sec: 47.23
// Errors: 0
// Get client stats
var clientStats = client.GetStats();
Console.WriteLine(clientStats);
```
### Get Connected Clients
```csharp
var clients = server.GetConnectedClients();
foreach (var client in clients)
{
Console.WriteLine($"{client.Username} - {client.RemoteEndPoint}");
}
```
## Event Handlers
### Server Events
```csharp
server.DataReceived += (s, e) =>
{
// Handle received data
Console.WriteLine($"From: {e.FromUsername}");
Console.WriteLine($"Data: {Encoding.UTF8.GetString(e.Data)}");
};
server.ClientConnected += (s, e) =>
{
Console.WriteLine($"Client connected: {e.Username} ({e.ClientId})");
};
server.ClientDisconnected += (s, e) =>
{
Console.WriteLine($"Client disconnected: {e.Username}");
};
server.ErrorOccurred += (s, e) =>
{
Console.WriteLine($"Error: {e.Message}");
Console.WriteLine($"Exception: {e.Exception}");
};
```
### Client Events
```csharp
client.DataReceived += (s, e) =>
{
// Handle received data
};
client.Connected += (s, e) =>
{
Console.WriteLine("Connected to server");
};
client.Disconnected += (s, e) =>
{
Console.WriteLine("Disconnected from server");
};
client.ErrorOccurred += (s, e) =>
{
Console.WriteLine($"Error: {e.Message}");
};
```
