Invalid Token '=' in class,struct or interface member declaration

Question

So I'm trying to use the request.Credentials function and am having the following error after building the solution..

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.Caching;


namespace com.tortoise.Controllers
{
    public class VebraController : ApiController
    {

        public class HttpHeader
        {
        string username = "foo";
        string password = "foo";

        string url = "www.test.com";

         HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

        .
        NetworkCredential myCredentials = new System.Net.NetworkCredential(username,password);
        string usernamePassword = (username + password);

        cache = new CredentialCache(); 
//Invalid Token '=' in class,struct,interface  member declaration, also for CredentialCache > //Method must have a return type.

            CredentialCache cache.Add(Uri url); "Basic",myCredentials); 
//Invalid token "Basic" in class,struct,or interface member declaration, same with the ')'.

            request.Credentials = CredentialCache cache; 
//Invalid Token '=' in class,struct,interface member declaration

            request.Headers.Add("Authorization", "Basic " + 
//Invalid Token '(' in class,struct,interface or declaration 
Convert.ToBase64String(Encoding.ASCII.GetBytes(usernamePassword)); 
//Invalid Token '(' in class,struct,interface or declaration same for GetBytes. and end of usernamePassword

            // Get the token from the response: 
            string token = response.GetResponseHeader("Token"); 


            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            response.Write (response.StatusCode) ;
 //Invalid Token '(' in class,struct,interface or declaration same for ')'
                }

I have included the errors received within the code above. Hopefully they will improve clarity of the issues I have.

Answer 1

Habib is correct. You need to put most of this code inside a method, you cannot have it all at the class level. Here I've put it inside the constructor for VebraController, but depending on the flow of execution of your program you may wish to do it differently. I also removed the inner class you were declaring for HttpHeader as I don't think you really meant to do that. The only remaining compilation error with this code is in the response.Write() line. I am not sure what you are trying to do there as HttpWebResponse does not include a method definition for Write.

Note that you don't need to have include statements for System.Net.Http etc. The ones I have included should be sufficient.

I have declared most of the variables outside the method--this is standard, you declare them as class members so you can use them anywhere in the class. If you only need them in a particular method you can declare them within the method itself. All the "action" parts of your program need to go in a method.

   using System;
   using System.Net;
   using System.Web;
   using System.Text;

    namespace com.tortoise.Controllers
    {
        public class VebraController : ApiController
        {
                private string username = "foo"; //class member 
                private string password = "foo"; //class member

                private static string url = "www.test.com"; //class member

                //this is where the constructor starts
                public VebraController() {

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

                NetworkCredential myCredentials = new System.Net.NetworkCredential(username,password);
                string usernamePassword = (username + password);

                CredentialCache cache = new CredentialCache(); 

                cache.Add(new Uri(url), "Basic", myCredentials); 

                request.Credentials = cache; 

                request.Headers.Add("Authorization", "Basic " + 
                    Convert.ToBase64String(Encoding.ASCII.GetBytes(usernamePassword)); 

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                // Get the token from the response: 
                string token = response.GetResponseHeader("Token"); 

                response.Write(response.StatusCode); //you need to fix this
            }
        }
    }

Answer 2

Do you mean

request.Credentials = new CredentialCache(); 

Instead of

request.Credentials = CredentialCache cache;
