我在工作中使用xamarin.forms，他们需要我使用wcf将移动应用程序连接到他们的sql服务器。我的wcf服务正在运行，我可以获取数据并将其发送到数据库，但是在尝试使用android模拟器时出现错误。

还有我的MainPage.xaml.cs

using ServiceReference1;
using Xamarin.Forms;
namespace MyApp
{
public partial class MainPage : ContentPage
{
ServiceReference1.Service1Client service = new ServiceReference1.Service1Client();
public MainPage()
{
InitializeComponent();
}
async void SubmitButton_Clicked(object sender, EventArgs e)
{
UserNames userInfo = new UserNames();
userInfo.Names = UserEntry.Text;
await service.AddnameAsync(userInfo.Names);
}
}
}
现在我的实际应用程序具有更多功能，但是出于测试目的，我制作了这个简单的应用程序，只是为了从数据库中调用信息并将信息发送到便携式计算机甚至我的手机上的android仿真器。现在公司代理可能是一个问题，但是即使我使用自己的互联网热点，我仍然会收到诸如代理名称解析之类的错误。...请帮助
