Socket.SendBufferSize Socket.SendBufferSize Socket.SendBufferSize Socket.SendBufferSize Property

定义

获取或设置一个值,该值指定 Socket 发送缓冲区的大小。Gets or sets a value that specifies the size of the send buffer of the Socket.

public:
 property int SendBufferSize { int get(); void set(int value); };
public int SendBufferSize { get; set; }
member this.SendBufferSize : int with get, set
Public 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)。An Int32 that contains the size, in bytes, of the send buffer. 默认值为 8192。The default is 8192.

异常

尝试访问套接字时出错。An error occurred when attempting to access the socket.

为设置操作指定的值小于 0。The value specified for a set operation is less than 0.

示例

下面的代码示例演示如何将SendBufferSize属性。The following code example demonstrates the use of the SendBufferSize property.

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 = gcnew 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 {0}", 
        tcpSocket->ExclusiveAddressUse);
    Console::WriteLine("  LingerState {0}, {1}", 
        tcpSocket->LingerState->Enabled,

    Console::WriteLine("  SendTimeout {0}",
        tcpSocket->SendTimeout);
    Console::WriteLine("  Ttl {0}",
        tcpSocket->Ttl);
    Console::WriteLine("  IsBound {0}",
        tcpSocket->IsBound);
    Console::WriteLine("");

	tcpSocket.SendTimeout = 1000;

	// Set the Time To Live (TTL) to 42 router hops.
	tcpSocket.Ttl = 42;

	Console.WriteLine("Tcp Socket configured:");

	Console.WriteLine("  ExclusiveAddressUse {0}", 
				tcpSocket.ExclusiveAddressUse);

	Console.WriteLine("  LingerState {0}, {1}",

				tcpSocket.ReceiveBufferSize);

	Console.WriteLine("  ReceiveTimeout {0}", 
				tcpSocket.ReceiveTimeout);

	Console.WriteLine("  SendBufferSize {0}", 
				tcpSocket.SendBufferSize);

	Console.WriteLine("  SendTimeout {0}", 
                                              tcpSocket.SendTimeout);

	Console.WriteLine("  Ttl {0}", 
                                              tcpSocket.Ttl);

                      Console.WriteLine("  IsBound {0}", 
                                              tcpSocket.IsBound);

	Console.WriteLine("");

注解

更大的缓冲区大小可能会延迟连接问题的识别。A larger buffer size might delay the recognition of connection difficulties. 请考虑增加缓冲区大小,如果传输大型文件,或者使用的高带宽、 高延迟连接 (如机顶盒宽带提供商。)Consider increasing the buffer size if you are transferring large files, or you are using a high bandwidth, high latency connection (such as a satellite broadband provider.)
