Assembly:

System.Net.Requests.dll

Source:

ServicePoint.cs

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

Property Value

Int32

A Int32 that contains the size, in bytes, of the receive buffer. The default is 8192.

Exceptions

ArgumentOutOfRangeException

The value specified for a set operation is greater than Int32.MaxValue.

Remarks

Caution

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