WebSocket。CreateServerBuffer与WebSocket。CreateClientBuffer

用法

WebSocket.CreateClientBuffer 主要用 ConnectAsync() 方法的实例 ClientWebSocket .

ClientWebSocket clientWS = new ClientWebSocket();
await clientWS.ConnectAsync(...);  // will create the client buffer

本质上唯一的区别是 CreateClientBuffer 允许您定义 sendBufferSize ,鉴于 CreateServerBuffer 不会(并且将默认 发送缓冲区大小 至16)。

似乎它们的存在主要是为了将关注点与 客户端WebSocket ServerWebSocket 它们都只是从抽象类派生的实例 WebSocket .

其他详细信息

看看 WebSocket.cs at Microsoft Reference Source 要查看实施情况:

// [WebSocketBuffer.cs] const int MinSendBufferSize = 16;

public static ArraySegment<byte> CreateClientBuffer(int receiveBufferSize, int sendBufferSize)
{
    WebSocketHelpers.ValidateBufferSizes(receiveBufferSize, sendBufferSize);

    return WebSocketBuffer.CreateInternalBufferArraySegment(receiveBufferSize, sendBufferSize, false);
}

public static ArraySegment<byte> CreateServerBuffer(int receiveBufferSize)
{
    WebSocketHelpers.ValidateBufferSizes(receiveBufferSize, WebSocketBuffer.MinSendBufferSize);

    return WebSocketBuffer.CreateInternalBufferArraySegment(receiveBufferSize, WebSocketBuffer.MinSendBufferSize, true);
}

WebSocketBuffer 但通过不同的最小值 发送缓冲区大小

这个 CreateServerBuffer() 方法将始终使用 MinSendBufferSize = 16 . 否则 CreateClientBuffer() 使用传递的值。
