이번 자바 작업중에 유니코드를 다루는게 있어서...

VS Express 설치해서 변환툴을 만들때 사용한 코드임!

## 한글 -> 유니코드
            string txt = UniCodeText.Text;
            string resultUniCode = "";
           
            foreach (char s in txt.ToCharArray())
            {
                if (char.IsLetter("" + s, 0))
                {
                    resultUniCode += "\\u";
                    byte[] bts = UnicodeEncoding.Unicode.GetBytes("" + s);
                    for (int loop = bts.Length - 1; loop >= 0; loop--)
                    {
                        resultUniCode += bts[loop].ToString("x2");
                    }
                }
                else
                {
                    resultUniCode += s;
                }
            } 
            UniCode.Text = resultUniCode;

## 유니코드 -> 한글!

            string Dir = Application.StartupPath + "\\UnicodeConvert\\";

            try
            {
                //unicode된 파일을 변환!!
                using (OpenFileDialog dlg = new OpenFileDialog())

                        File.Exists(dlg.FileName))

                        string writeFileContent = "";

                        char[] uniarray = readFile.ToCharArray();

                        {
                            char c = uniarray[loop];
                            char u = '\0';
                            if (loop + 1 < uniarray.Length) u = uniarray[loop + 1];

                                                                                                                  .Replace("\\", "/");
                        if(MessageBox.Show("메모장에서 보시겠습니까?", "확인", 

                                               MessageBoxButtons.OKCancel) == System.Windows.Forms.DialogResult.OK )
                            System.Diagnostics.Process.Start("notepad.exe", Dir + Path.GetFileName(dlg.FileName));

            }
            catch( Exception ex ){
