Heroic Gunz - C# Launcher

Lets go over what's wrong with this and why no one should use it.

1. Synchronous downloads.

Code:

---



namespace GLauncher{
    class PatchFile{
        public bool checkPatchFile(string from){
            try{
                WebClient PatchFile = new WebClient();
                PatchFile.DownloadFile(from+"ZPatch.xml", "ZPatch.xml");
                return true;
            }catch(WebException exeption){
                MessageBox.Show(Convert.ToString(exeption));
                return false;
            }
        }
    }

---

2. Using MD5 hashing instead of a decent algorithm.

Code:

---

    class Hash{
        public string GetMD5HashFromFile(string fileName){
            FileStream file = new FileStream(fileName, FileMode.Open);
            MD5 md5 = new MD5CryptoServiceProvider();
            byte[] retVal = md5.ComputeHash(file);
            file.Close();


            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < retVal.Length; i++){
                sb.Append(retVal[i].ToString("x2"));
            }
            return sb.ToString();
        }
    }

---

3. Sleeping on a main thread.

Code:

---

        private void checkPatchFile(){
            PatchFile checkPatch = new PatchFile();
            if (!checkPatch.checkPatchFile(Convert.ToString(this.PatchLocation))){
                this.TransferSpeed.Visible = false;
                this.Information.Text = "Exiting Gunz Launcher.";
                this.Information.Refresh();
                Thread.Sleep(500);
                this.Information.Text = "Exiting Gunz Launcher..";
                this.Information.Refresh();
                Thread.Sleep(500);
                this.Information.Text = "Exiting Gunz Launcher...";
                this.Information.Refresh();
                Thread.Sleep(500);
                Environment.Exit(0);
            }else{
                this.checkFiles();
            }
        }

---

4. Do I even need to explain this?

Code:

---

        static bool FilesAreEqual(FileInfo first, FileInfo second){
            if (first.Length != second.Length)
                return false;
            int iterations = (int)Math.Ceiling((double)first.Length / BYTES_TO_READ);
            using (FileStream fs1 = first.OpenRead())
            using (FileStream fs2 = second.OpenRead()){
                byte[] one = new byte[BYTES_TO_READ];
                byte[] two = new byte[BYTES_TO_READ];
                for (int i = 0; i < iterations; i++){
                    fs1.Read(one, 0, BYTES_TO_READ);
                    fs2.Read(two, 0, BYTES_TO_READ);
                    if (BitConverter.ToInt64(one, 0) != BitConverter.ToInt64(two, 0))
                        return false;
                }
            }
            return true;
        }
