我正在尝试使用 Xamarin 和 WebSocket4Net 进行简单的测试，但它在 Open() 上失败，并显示“操作已经在进行中”。下面的示例代码：
using Xamarin.Forms;
using WebSocket4Net;
using System;
using SuperSocket.ClientEngine;
namespace SocketTest
{
public partial class SocketTest : ContentPage
{
private WebSocket websocket;
public SocketTest()
{
InitializeComponent();
}
void Handle_Clicked(object sender, System.EventArgs e)
{
websocket = new WebSocket("ws://echo.websocket.org/");
websocket.Opened += Websocket_Opened;
websocket.Error += Websocket_Error;
websocket.Closed += Websocket_Closed;
websocket.MessageReceived += Websocket_MessageReceived;
websocket.Open();
}
private void Websocket_Error(object sender, ErrorEventArgs e)
{
Console.WriteLine(e.Exception.Message);
}
private void Websocket_MessageReceived(object sender, EventArgs e)
{
Console.WriteLine(e.ToString());
}
private void Websocket_Closed(object sender, EventArgs e)
{
Console.WriteLine(e.ToString());
}
private void Websocket_Opened(object sender, EventArgs e)
{
websocket.Send("Hello World!");
}
}
}
我从标准的多平台项目 (PCL) 开始，并添加了一个按钮来启动连接。
Versions:
0.15.0 WebSocket4Net
0.8.0.13 SuperSocket
PCL 配置为：.NET Standard Platform = netstandard1.4
我对 .NET/Xamarin 还很陌生，但我拥有多年的软件开发经验。
