在 .NET 核心 3.1 中包含 WCF 客户端的代理用户名和密码？

Question

我有一个 .net 核心 3.1 客户端应用程序，它调用位于 inte.net 中的 SOAP 服务。 我需要一些帮助来摆脱公司代理，下面是目前为止的代码。

var _InfoRequest = new ClientService.InfoRequest()
    {
        var1 = "",
        var2 = ""
    };

var binding = _client.Endpoint.Binding as BasicHttpBinding;
binding.ProxyAddress = new Uri("http://proxy-ip-address:8585");
binding.UseDefaultWebProxy = false;
binding.BypassProxyOnLocal = false;

var _response =await _client.getCustomerInfoAsync(_InfoRequest).ConfigureAwait(false);

如何在上述代码中使用我的 Active Directory 帐户（用户名和密码）通过公司代理服务器访问外部服务。

更新

我有一个例外如下：

Connection ID "16357073852515221623", Request ID "8000007a-0001-e300-b63f-84710c7967bb": An unhandled exception was thrown by the application.

Exception:

顺便说一句，可以从托管我的服务的 web 服务器访问公司代理服务器，为了证明这一点，我将与我在 C# 代码中使用的相同的代理设置添加到IE 浏览器，它工作正常。

可以通过这种方式传递用户名、密码和域：

  _InfoRequest .ClientCredentials.Windows.ClientCredential.UserName = "x";
  _InfoRequest .ClientCredentials.Windows.ClientCredential.Password = "pwd";
  _InfoRequest .ClientCredentials.Windows.ClientCredential.Domain = "Domain";
