I use C# examples and use the source code for CreateCustomerProfile: http://developer.authorize.net/api/reference/#customer-profiles

I use only code from this example and I have the exception "System.Net.WebException" in string

controller.Execute();

Can anyone help me?

What version of the .Net framework are you using? If you are using .Net framework 4.5, try adding the following at the beginning of the function where you make a webrequest:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
