Is a field but is used like a type

I have taken a code snippet and am trying to mold it to my needs but am getting errors early on.
It should be a simple get file from A and save file to B process.
But I am getting these errors
'HubbleDocs.GetFile.copyService' is a 'field' but is used like a 'type'      
and
A field initializer cannot reference the non-static field, method, or property 'HubbleDocs.GetFile.fieldInfo'      

Here is the code in full, much appreciated if someone could get me over the line on this please

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

namespace HubbleDocs
{
    public class GetFile
    {

        string webUrl = "http://localhost:1000";
        FileCopy.Copy copyService = new FileCopy.Copy();
        copyService.Url = webUrl +"/_vti_bin/copy.asmx";
         NetworkCredential m_credentials = new NetworkCredential(UserId, Pwd, Domain)
             copyService.Credentials = m_credentials;

        //Source and Destination Document URLs
         string sourceUrl = "http://localhost:1000/Shared Documents/Sample.doc";
         string destinationUrl = "C:\\Documents\\Sample.doc";

        //Variables for Reading metadata’s of a document
         FileCopy.FieldInformation fieldInfo = new FileCopy.FieldInformation();
         FileCopy.FieldInformation[] fieldInfoArray = { fieldInfo };
         FileCopy.CopyResult cResult1 = new FileCopy.CopyResult();
         FileCopy.CopyResult cResult2 = new FileCopy.CopyResult();
         FileCopy.CopyResult[] cResultArray = { cResult1, cResult2 };

        

        //Receive a Document Contents  into Byte array (filecontents)
         byte[] fileContent; // no need to initialize the GetItem takes care of that.
         copyService.GetItem(sourceUrl, out fieldInfoArray, out fileContents);

        //Create a new file and write contents to that document
         FileStream fStream = new FileStream(destinationUrl, FileMode.Create, FileAccess.ReadWrite);
        fStream.Write(fileContents, 0, fileContents.Length);
        fStream.Close();

    }
}
