Question

您好我正在多次调用具有不同参数值的Async方法，在完成的事件中给出相同的结果。

client.ListAllLookupValuesByTypeCompleted += client_ListAllAddressFormatCompleted;
client.ListAllLookupValuesByTypeAsync("AddressFormat");

client.ListAllLookupValuesByTypeCompleted += client_ListAllPhoneFormatCompleted;
client.ListAllLookupValuesByTypeAsync("PhoneFormat");



void client_ListAllAddressFormatCompleted(object sender, ListAllLookupValuesByTypeCompletedEventArgs e)
        {
            cmbAddressFormat.ItemsSource = e.Result;
        }


void client_ListAllPhoneFormatCompleted(object sender, ListAllLookupValuesByTypeCompletedEventArgs e)
        {
            cmbPhonePrintFormat.ItemsSource = e.Result;
        }

请帮帮我。感谢。

您可以创建client的新实例。

...
var client = new XyzClient();
client.ListAllLookupValuesByTypeCompleted += client_ListAllAddressFormatCompleted;
client.ListAllLookupValuesByTypeAsync("AddressFormat");

client = new XyzClient();
client.ListAllLookupValuesByTypeCompleted += client_ListAllPhoneFormatCompleted;
client.ListAllLookupValuesByTypeAsync("PhoneFormat");
...


void client_ListAllAddressFormatCompleted(object sender, ListAllLookupValuesByTypeCompletedEventArgs e)
{
    cmbAddressFormat.ItemsSource = e.Result;
}


void client_ListAllPhoneFormatCompleted(object sender, ListAllLookupValuesByTypeCompletedEventArgs e)
{
   cmbPhonePrintFormat.ItemsSource = e.Result;
}

另一个解决方案是在第一个调用处理程序中进行第二次调用（可能还是创建新的客户端实例）。
