private void SendHex_TextBox_Leave(object sender, EventArgs e)
        {
            int temp = 0;
            string str = "";
            SendHex_TextBox.Text = " ";
            for (int i = 0; i < SendHex_TextBox.Text.Length; i )
            {
                if (SendHex_TextBox.Text[i] == ' ')
                {
                    if (temp == 1)//单个字符
                    {
                        temp = 0;
                        str = "0" SendHex_TextBox.Text.Substring(i - 1, 1) " ";
