//获取扫描枪barcode

        if (message2 != "" && message2.Length < 22 && (!message2.Contains("WG")))
        {
            //截取字段（产品族、壳体、控制器型号、极数）
            string family = message2.Substring(14, 2);
            string housing = message2.Substring(16, 2);
            string controller_type = message2.Substring(18, 2);
            string pole = message2.Substring(20, 1);
		}

二、提取固定字符间的字符

	/// <summary>
    /// 提取打印内容
    /// </summary>
    /// <param name="teshubeizhu"></param>
    private void GetPrintContent(string  teshubeizhu )
    {
        //获取#号的数量
        int count = GetCharCount(teshubeizhu);
        if (teshubeizhu != "" && count == 2)
        {
            //提取打印内容
            printContent = Regex.Matches(teshubeizhu, "(?<=beginstr).*?(?=endstr)").ToString();
        }
    }
	        /// <summary>
    /// 计算字符串个数
    /// </summary>
    /// <param name="InputValue"></param>
    /// <returns></returns>
    private int GetCharCount(string InputValue)
    {
        return InputValue.Split("#").Length - 1;
    }
