如何以ddmmyyhhmmss格式生成发票编号

how to generate the Invoice number in the format of ddmmyyhhmmss

推荐答案

string value = DateTime.Now.ToString("ddMMyyhhmmss");

刚刚注意到 - 你说发票号码？

通常有关于发票编号的规则，因为它们必须是连续的（以便税务局可以确保没有任何遗漏） - 这不会那样做，并且会结果可能是一个坏主意。

Just noticed - you said "invoice number"?
There are normally rules about invoice numbers, in that they must be sequential (so that the Tax office can be sure that there aren't any missing) - this does not do that, and would probably be a bad idea as a result.

dd-两位数d吃了

ss-seconds in digis。

int ctr, len;
            string code;
            DataRow drr;
            string qry = "select top 1 id from client_bill_Tb order by id desc";
            DataTable dt = cbbal.GetData(qry);
            len = dt.Rows.Count - 1;
            drr = dt.Rows[len];
            code = drr["id"].ToString();
            ctr = Convert.ToInt32(code);

            if ((ctr >= 0) && (ctr < 9))
            {
                ctr = ctr + 1;
                txtInvoice.Text = ctr + DateTime.Now.ToString("/MMyyyy");
            }
            else if ((ctr >= 9) && (ctr < 100))
            {
                ctr = ctr + 1;
                txtInvoice.Text = ctr + DateTime.Now.ToString("/MMyyyy");
            }
            else if (ctr >= 99)
            {
                ctr = ctr + 1;
                txtInvoice.Text = ctr + DateTime.Now.ToString("/MMyyyy");
           }
