C # Barcode generation and printing instance code _c# tutorial

The example of this article for you to share the C # barcode generation and printing methods for your reference, the specific content as follows

String barcodestring = "13043404455";//Barcode int imgwidth = 520;

    int imgheight = 120;  Print button private void Button1_Click (object sender, EventArgs e) {//Materialized print object PrintDocument PrintDocument1

      = new PrintDocument ();   Set the paper for printing to customize the size of the paper (in mm).

      You can also not set//printdocument1.defaultpagesettings.papersize = new PaperSize ("Custum", 585, 800) when the print height is uncertain;

      Registers the PrintPage event, which triggers the event printdocument1.printpage + = new Printpageeventhandler (this.printdocument1_printpage) when printed on each page;

      Start printing printdocument1.print ();
      Print Preview//printpreviewdialog ppd = new PrintPreviewDialog (); Ppd.
      Document = PrintDocument1; Ppd.
    ShowDialog ();  }//Print event private void Printdocument1_printpage (object sender, PrintPageEventArgs e) {StringBuilder SB
      = new StringBuilder (); Sb.
      Append ("\r\n\r\n\r\n"); Sb.
      Append ("******* Xinglong supermarket *******\r\n"); Sb.
