我已经做了一个C#项目，我试图连接到我的Business Central云沙盒。
在Business Central中，我用一个新的代码单元做了一个扩展，它有一个我称为“MHSTest”的函数，它只返回一个文本。
在Visual Studio中，我创建了连接到Business Central中SOAP URL的服务引用。因此，我可以在Visual Studio中看到我的函数名“MHSTest”。
当我在Visual Studio中编写此代码时，我得到一个错误，因为它试图匿名连接：

var client = new MHSTest.CSharpCodeunit_PortClient();
myTextBox.Text = client.MHSTest();

如果我尝试下面的方法，我会得到一个错误消息，说“https”是无效的。它必须是“http”。

string endpoint = "">api.businesscentral.dynamics.com/.../CSharpCodeunit";
var binding = new BasicHttpBinding();
binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
binding.MaxBufferSize = 999999;
binding.MaxReceivedMessageSize = 999999;

var client = new MHSTest.CSharpCodeunit_PortClient(binding, new EndpointAddress(endpoint));

myTextBox.Text = client.MHSTest();

如何连接到Business Central并获取（或设置）数据？
