Socket.SendBufferSize 属性   
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
获取或设置一个值,该值指定 Socket 发送缓冲区的大小。
public:
 property int SendBufferSize { int get(); void set(int value); };public int SendBufferSize { get; set; }member this.SendBufferSize : int with get, setPublic Property SendBufferSize As Integer属性值
Int32,它包含发送缓冲区的大小(以字节为单位)。 默认值取决于操作系统。
例外
尝试访问套接字时出错。
为设置操作指定的值小于 0。
示例
下面的代码示例演示如何使用 SendBufferSize 属性。
static void ConfigureTcpSocket(Socket tcpSocket)
{
    // Don't allow another socket to bind to this port.
    tcpSocket.ExclusiveAddressUse = true;
    // The socket will linger for 10 seconds after
    // Socket.Close is called.
    tcpSocket.LingerState = new LingerOption (true, 10);
    // Disable the Nagle Algorithm for this tcp socket.
    tcpSocket.NoDelay = true;
    // Set the receive buffer size to 8k
    tcpSocket.ReceiveBufferSize = 8192;
    // Set the timeout for synchronous receive methods to
    // 1 second (1000 milliseconds.)
    tcpSocket.ReceiveTimeout = 1000;
    // Set the send buffer size to 8k.
    tcpSocket.SendBufferSize = 8192;
    // Set the timeout for synchronous send methods
    // to 1 second (1000 milliseconds.)
    tcpSocket.SendTimeout = 1000;
    // Set the Time To Live (TTL) to 42 router hops.
    tcpSocket.Ttl = 42;
    Console.WriteLine("Tcp Socket configured:");
    Console.WriteLine($"  ExclusiveAddressUse {tcpSocket.ExclusiveAddressUse}");
    Console.WriteLine($"  LingerState {tcpSocket.LingerState.Enabled}, {tcpSocket.LingerState.LingerTime}");
    Console.WriteLine($"  NoDelay {tcpSocket.NoDelay}");
    Console.WriteLine($"  ReceiveBufferSize {tcpSocket.ReceiveBufferSize}");
    Console.WriteLine($"  ReceiveTimeout {tcpSocket.ReceiveTimeout}");
    Console.WriteLine($"  SendBufferSize {tcpSocket.SendBufferSize}");
    Console.WriteLine($"  SendTimeout {tcpSocket.SendTimeout}");
    Console.WriteLine($"  Ttl {tcpSocket.Ttl}");
    Console.WriteLine($"  IsBound {tcpSocket.IsBound}");
    Console.WriteLine("");
}
注解
较大的缓冲区大小可能会延迟对连接困难的识别。 如果要传输大型文件,或者使用的是高带宽、高延迟连接 ((如卫星宽带提供商),请考虑增加缓冲区大小。)
