使用C＃清理RFID阅读器中的数据

Question

我能够使用下面的代码从RFID阅读器读取数据，但我得到的输出有一个特殊的字符，第二个问题是我有一个来自我公司的现有SQL数据库，里面的数据与什么不匹配我正进入（状态。我的RFID阅读器品牌是SMARTCODE

            this.BeginInvoke(new SetTextDeleg(DisplayOutput), new object[] { indata });

        }


        public void DisplayOutput(string displayData)
        {
            string compdata = "";

            if (compdata != displayData)
            {
               textBox1.Clear();
                String first = displayData;

                String s = first;


            }


            String New = textBox1.Text;


            textBox1.Text = New;

            string[] lines = { New };
            System.IO.File.WriteAllLines(@"C:\Users\DarkVader\Desktop\output.txt", lines);


        }


        private void textBox1_TextChanged_1(object sender, EventArgs e)
        {

            String ID = textBox1.Text;
            String Fname = "";



            try
            {

                using (SqlConnection connection = new SqlConnection("Data Source=DTSQL03;Initial Catalog=TableBadge;Integrated Security=True"))
                {
                    SqlCommand command =
                    new SqlCommand("select * from CBadge WHERE cardno LIKE '%" + ID + "%'", connection);
                    connection.Open();

                    SqlDataReader read = command.ExecuteReader();

                    while (read.Read())
                    {
                        Fname = (read["firstname"].ToString());


                        fname.Text = Regex.Replace(Fname, @"\s+", " ");

                    }
                    read.Close();
                }


            }
            catch
            {

                MessageBox.Show("NO Connection");

            }


        }


    }
}

这是我得到的数据

这是我必须匹配的SQL数据库中的数据。

任何帮助都会很棒。谢谢！

更新

好的，我可以使用下面的代码清除特殊字符。

String New = textBox1.Text;

textBox1.Text = Regex.Replace(New, @"[^0-9a-zA-Z]+", "");

现在我的问题是在当前的SQL服务器上获得正确的格式化。
