UdpClient::ExclusiveAddressUse Property
Gets or sets a Boolean value that specifies whether the UdpClient allows only one client to use a port.
Assembly: System (in System.dll)
Property Value
Type: System::Booleantrue if the UdpClient allows only one client to use a specific port; otherwise, false. The default is true for Windows Server 2003 and Windows XP Service Pack 2 and later, and false for all other versions.
| Exception | Condition |
|---|---|
| SocketException | An error occurred when attempting to access the underlying socket. |
| ObjectDisposedException | The underlying Socket has been closed. |
By default, multiple clients can use a specific port; however, only one of the clients can perform operations on the network traffic sent to the port. You can use the ExclusiveAddressUse property to prevent multiple clients from using a specific port.
This property must be set before the underlying socket is bound to a client port. If you call UdpClient::UdpClient(Int32), UdpClient::UdpClient(Int32, AddressFamily), UdpClient::UdpClient(IPEndPoint^), or UdpClient::UdpClient(String^, Int32), the client port is bound as a side effect of the constructor, and you cannot subsequently set the ExclusiveAddressUse property
The default value for this property is true for Service Pack 2 and later.
The default value for this property is true.
The application must run as Administrator to use this property.
For Service Pack 1, the application must run as Administrator to use this property.
The following code example creates a UdpClient, and gets and sets the ExclusiveAddressUse property.
