Assembly: System (in System.dll)
Property Value
Type: System::Booleantrue if the TcpClient 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 Connect, BeginConnect, TcpClient(IPEndPoint^), or TcpClient(String^, Int32), the client port is bound as a side effect of the method, and you cannot subsequently set the ExclusiveAddressUse property
The default value for this property is true for Service Pack 2 and later. For Service Pack 1, the application must run as Administrator to use this property.
The default value for this property is true.
The application must run as Administrator to use this property.
The following code example creates a TcpClient and gets and sets the value of the ExclusiveAddressUse property.
