c# - Drawing text using font from file not working -

i'm trying load private font, using system.drawing.text.privatefontcollection. the goal not have install font on system.

all examples find pretty simple. load using privatefontcollection , create font it.

below simple class test it.

it works if install font. in not, text printed in dialog preview using default font. checked font correctly loaded. i'm missing ? thank help.

public partial class test : form {     private printdocument printdocument1 = new printdocument();     system.drawing.text.privatefontcollection privatefonts;     private font _barcodefont;      public test()     {         initializecomponent();     }     private void test_load(object sender, eventargs e)     {         privatefonts = new system.drawing.text.privatefontcollection();         privatefonts.addfontfile("code128.ttf");     }      private void btbtest_click(object sender, eventargs e)     {         printdocument pd = new printdocument();          pd.printpage += new printpageeventhandler(this.pd_printpage);         pd.documentname = "label";          printpreviewdialog pp = new printpreviewdialog();         pp.document = pd;         pp.windowstate = formwindowstate.normal;         pp.showdialog();      }     private void pd_printpage(object sender, printpageeventargs ev)     {         _barcodefont = new font(privatefonts.families[0], 12, fontstyle.regular);         ev.graphics.drawstring("should bar code", _barcodefont, brushes.black, 0, 0);         ev.hasmorepages = false;     }       } 

try this

 private void pd_printpage(object sender, printpageeventargs ev) {     font _barcodefont = new font(privatefonts.families[0], 12, fontstyle.regular);     ev.graphics.drawstring("should bar code", _barcodefont, brushes.black, 0, 0);     ev.hasmorepages = false; }     

, remove
private font _barcodefont;
