我有一个WCF服务合同,旨在通过TCP网络从剪贴板发送字符串,并由winform列表框接收和显示,我已设法连接两个winforms,但是我无法获取显示的URL在列表框中。

</service>
</services>
</system.serviceModel>

[ServiceContract]
public interface IApplicationService
{
[OperationContract(IsOneWay = true)]
void GetURL();
}
public class ApplicationService : IApplicationService
{
public void GetURL()
{
var addCopy = Clipboard.GetText(TextDataFormat.Text);
WCF.listURL.Items.AddRange(addCopy.Split(new[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries));
}
}
public static void WCF_Load(object sender, EventArgs e)
{
//Establish connection with Service
ServiceHost svc = new ServiceHost(typeof(ApplicationService));
svc.Credentials.Peer.MeshPassword = "hehe";
svc.Open();
//Both Server and Client binding should match
NetPeerTcpBinding np2p = new NetPeerTcpBinding();
np2p.Security.Mode = SecurityMode.None;
}
private void btnSendURL_MouseClick(object sender, EventArgs e)
{
ApplicationService url = new ApplicationService();
url.GetURL();
}
您可能会注意到在ApplicationService.cs中我使用WCF.listURL,这是因为我不知道如何正确调用表单列表框; ApplicationService中的listURL。
答案 0 :(得分:0)
正如我在评论中提到的,除了请求数据或执行其他操作之外,服务应该对客户端一无所知。我建议重写服务以仅返回数据,并让客户端应用程序将该数据绑定到ListBox
。但是,您需要删除IsOneWay
属性。像这样:
[ServiceContract]
public interface IApplicationService
{
[OperationContract]
string GetURL();
}
在上面的代码中,删除了单向属性,该方法返回string
。我使用string
代替string
数组 - 客户端可以确定如何处理数据(拆分或不拆分,重新格式化等)。
public class ApplicationService : IApplicationService
{
public string GetURL()
{
return Clipboard.GetText(TextDataFormat.Text);
}
}
该实现只返回剪贴板中的文本字符串。
private void btnSendURL_MouseClick(object sender, EventArgs e)
{
ApplicationService url = new ApplicationService();
string data = url.GetURL();
listBox1.Items.AddRange(addCopy.Split(new[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries));
}
最后,应用程序将调用服务方法并获取返回的数据。然后,它会将数据添加到ListBox
(示例中名为listBox1
)。现在,您已将WCF服务与客户端分离,应该是这样。
