TCnUdpClient Class
Provides User Datagram Protocol (UDP) network services.
type TCnUdpClient = class(TClrBaseComponent) end;
The TCnUdpClient type exposes the following members.
| Name | Description | |
|---|---|---|
 | Create(TComponent) | Creates and initializes a TCnUdpClient instance. (Overrides TClrBaseComponent.Create(TComponent).) |
| Destroy | Frees the resources allocated with a TCnUdpClient instance. (Overrides TClrBaseComponent.Destroy.) |
| Name | Description | |
|---|---|---|
 | Available | Gets the amount of data received from the network that is available to read. |
| Client | Gets or sets the underlying network Socket. |
 | DefaultClrObject | Get the common language runtime object interface for this component. (Inherited from TClrBaseComponent.) |
| DontFragment | Gets or sets a Boolean value that specifies whether the UdpClient allows Internet Protocol (IP) datagrams to be fragmented. |
| EnableBroadcast | Gets or sets a Boolean value that specifies whether the UdpClient may send or receive broadcast packets. |
| ExclusiveAddressUse | Gets or sets a Boolean value that specifies whether the UdpClient allows only one client to use a port. |
| MulticastLoopback | Gets or sets a Boolean value that specifies whether outgoing multicast packets are delivered to the sending application. |
| TimetoLive | Gets or sets a value that specifies the Time to Live (TTL) value of Internet Protocol (IP) packets sent by the UdpClient. |
| Name | Description | |
|---|---|---|
| AllowNatTraversal(Boolean) | Enables or disables Network Address Translation (NAT) traversal on a UdpClient instance. |
| Close | Closes the UDP connection. |
| Connect(String,Integer) | Overloaded. Establishes a default remote host using the specified host name and port number. |
| Connect(_IPAddress,Integer) | Overloaded. Establishes a default remote host using the specified IP address and port number. |
| Connect(_IPEndPoint) | Overloaded. Establishes a default remote host using the specified network endpoint. |
| Dispose | Releases the resources used by the Component. (Inherited from TClrBaseComponent.) |
 | DoGetDefaultClrObject | Represents method |
| DoGetDotNetBaseComponent | Represents method |
| DropMulticastGroup(_IPAddress) | Overloaded. Leaves a multicast group. |
| DropMulticastGroup(_IPAddress,Integer) | Overloaded. Leaves a multicast group. |
| GetClrObject | Represents method |
| JoinMulticastGroup(Integer,_IPAddress) | Overloaded. Adds a UdpClient to a multicast group. |
| JoinMulticastGroup(_IPAddress) | Overloaded. Adds a UdpClient to a multicast group. |
| JoinMulticastGroup(_IPAddress,Integer) | Overloaded. Adds a UdpClient to a multicast group with the specified Time to Live (TTL). |
| JoinMulticastGroup(_IPAddress,_IPAddress) | Overloaded. Adds a UdpClient to a multicast group. |
| Receive(_IPEndPoint) | Returns a UDP datagram that was sent by a remote host. |
| ReceiveAsync | Returns a UDP datagram asynchronously that was sent by a remote host. |
| Receive_(_IPEndPoint) | Returns a UDP datagram that was sent by a remote host. |
| RegisterEventCallBack(ClrWString,Pointer) | Add an event to the instance using the specified event name and function pointer which is the event handler. The RegisterEventCallBack method does not directly add the event handler to the event. A hooking mechanism is used such that if the event is fired, the hook event is also fired which in turn calls the function pointer. (Inherited from TClrBaseComponent.) |
| RegisterEventSource | Register the Delphi object which will raise the .Net event handler. (Inherited from TClrBaseComponent.) |
| Send(TArray,Integer) | Overloaded. Sends a UDP datagram to a remote host. |
| Send(TArray,Integer,String,Integer) | Overloaded. Sends a UDP datagram to a specified port on a specified remote host. |
| Send(TArray,Integer,_IPEndPoint) | Overloaded. Sends a UDP datagram to the host at the specified remote endpoint. |
| Send(_ByteArray,Integer) | Overloaded. Sends a UDP datagram to a remote host. |
| Send(_ByteArray,Integer,String,Integer) | Overloaded. Sends a UDP datagram to a specified port on a specified remote host. |
| Send(_ByteArray,Integer,_IPEndPoint) | Overloaded. Sends a UDP datagram to the host at the specified remote endpoint. |
| SendAsync(TArray,Integer) | Overloaded. Sends a UDP datagram asynchronously to a remote host. |
| SendAsync(TArray,Integer,String,Integer) | Overloaded. Sends a UDP datagram asynchronously to a remote host. |
| SendAsync(TArray,Integer,_IPEndPoint) | Overloaded. Sends a UDP datagram asynchronously to a remote host. |
| SendAsync(_ByteArray,Integer) | Overloaded. Sends a UDP datagram asynchronously to a remote host. |
| SendAsync(_ByteArray,Integer,String,Integer) | Overloaded. Sends a UDP datagram asynchronously to a remote host. |
| SendAsync(_ByteArray,Integer,_IPEndPoint) | Overloaded. Sends a UDP datagram asynchronously to a remote host. |
| UnRegisterEventCallBack(ClrWString,Pointer) | Remove an event from the instance using the specified event name and function pointer which is the event handler. (Inherited from TClrBaseComponent.) |
| UnRegisterEventSource | Unregister the Delphi object which raised the .Net event handler. (Inherited from TClrBaseComponent.) |
