Question

我遇到了SslStream.WriteAsync

的恼人问题

这是代码

public void Send(PacketWriter writer)
{
    var buffer = writer.GetWorkspace();

    _sslStream.WriteAsync(buffer, 0, buffer.Length);
}

以极高的速度写入数据时，它告诉我

The beginwrite method cannot be called when another write operation is pending

[注意]：我的意思是像这样的高速

for (var i = 0 ; i <= 1000; i++)
{
    Send(somedata);
}

Answer 1

您必须等到上一次异步写入完成。

更改您的发送方式以返回Task：

public Task Send(PacketWriter writer)
{
    var buffer = writer.GetWorkspace();
    return _sslStream.WriteAsync(buffer, 0, buffer.Length);
}

调用方法async，然后等待每个发送操作完成：

for (var i = 0 ; i <= 1000; i++)
{
    await Send(somedata);
}

Answer 2

可以尝试-

 private static void send_data(SslStream socket_stream, byte[] data)
        {
          Task task = new Task(() => { socket_stream.Write(data, 0, data.Length); });
          task.RunSynchronously();
          task.Wait();
        }

这将确保所有消息均以无错误的方式发送，

c＃高速使用SslStream.WriteAsync
