Question

当应用程序启动时，它将运行DispatcherTimer。每10秒，它将运行running（）函数，而running（）函数使用web服务并且运行良好。当系统无法获取Web服务时，它会弹出“System.timeOut异常”。如何解决异常？

感谢您提供的任何帮助！

private void running()
    {    
         ServiceReference1.WebServiceSoapClient test = new ServiceReference1.WebServiceSoapClient();

         test.ReadTotalOutstandingInvoiceCompleted += new EventHandler<ServiceReference1.ReadTotalOutstandingInvoiceCompletedEventArgs>(serviceClient);  

         test.ReadTotalOutstandingInvoiceAsync();
    }

private void serviceClient(object sender, ReadTotalOutstandingInvoiceCompletedEventArgs e)

    {
         tbTesting.Text = e.Result.ToString();

         tbTextbox2.Text = "You have " + tbTesting.Text + " Invoice !!";
         ...
         MessageBox.Show("You have " + tbTesting.Text + " new Invoice" +Environment.NewLine+ Environment.NewLine+ DateTime.Now, "Invoice", MessageBoxButton.OK);
         ...
        }

在reference.cs

中

public string EndReadTotalOutstandingInvoice(System.IAsyncResult result) {

        object[] _args = new object[0];
        string _result = ((string)(base.EndInvoke("ReadTotalOutstandingInvoice", _args, result)));
        return _result;
    }

这只是告诉你，无论web服务做了什么都已经超时并且可能无法使用。通过“解决异常”很难说出你的意思，如果网络服务不可用，你可能无能为力。

“System.timeOut异常”类型的未处理异常
