WCFclient仅操作Async .Net core 2.0 [英] WCFclient operation only Async .Net core 2.0

问题描述

我在asp.net core 2.0中将wcf服务端点添加到了连接的服务中，然后尝试使用它，但是对于客户端，只有以..async结尾的功能

I added wcf services end point in asp.net core 2.0 to connected services and then I try to use that but with client there is only functions which ended with ..async

我不想使用... async。但是没有.async就没有功能

I don't want to use ...async.But there is no function without .async

这是什么问题我该怎么办？

What is problem with this?What should I do?

而不是使用它

 var response = SystemClient.SearchCountriesAsync(....

我要使用它

 var response = SystemClient.SearchCountries(...

但出现错误

错误CS1061'SystemClient'不包含'SearchCountries'的定义，也没有扩展方法'SearchCountries'接受类型为'SystemClient'的第一个参数可以找到（您是否缺少using指令或程序集引用？）

Error CS1061 'SystemClient' does not contain a definition for 'SearchCountries' and no extension method 'SearchCountries' accepting a first argument of type 'SystemClient' could be found (are you missing a using directive or an assembly reference?)

推荐答案

您的客户端不会公开同步方法，但这对您来说应该不是问题。

Your client does not expose synchronous method but that shouldn't be a problem for you.

不是异步调用该方法，而是这样做：

Instead of asynchronously calling the method just do this:

response = SystemClient.SearchAirportsAsync(credentials, SystemHelperLanguageTypes.English, SystemHelperSearchTypes.CodeSearch, "ist").Result;

这将同步调用该方法，因为它将阻止该调用。在此处查看。

This will call the method synchronously as it will block the call. Check John Skeets answer here.

话虽如此，我建议您使用提供的async方法。为了支持这一点，您必须将Action签名更改为：

That being said I would recomend you use the async method that is provided. To support that you would have to change the Action signature to this:

public async Task<IActionResullt> Index()
{
   SystemClient SystemClient = new SystemClient();
   Credential credential = new Credential();
   credential.UserName = "username";
   credential.UserPassword = "****";

   var response1 = await SystemClient.SearchCountriesAsync(credentials, SystemHelperLanguageTypes.English, SystemHelperSearchTypes.CodeSearch, "TR");
   var response = await SystemClient.SearchAirportsAsync(credentials, SystemHelperLanguageTypes.English, SystemHelperSearchTypes.CodeSearch, "ist");

   //Do whatever you do with those responses

   ViewBag.Language = "ar";
   return View();
}
