Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets or sets the size of the receiving buffer for the socket used by this ServicePoint.
public:
property int ReceiveBufferSize { int get(); void set(int value); };
public int ReceiveBufferSize { get; set; }
member this.ReceiveBufferSize : int with get, set
Public Property ReceiveBufferSize As Integer
A Int32 that contains the size, in bytes, of the receive buffer. The default is 8192.
The value specified for a set operation is greater than Int32.MaxValue.
The following code example sets the value of this property.

Waarschuwing
WebRequest
, HttpWebRequest
, ServicePoint
, and WebClient
are obsolete, and you shouldn't use them for new development. Use HttpClient instead.
