使用文件中的字体绘制文本不起作用

Question

I'm trying to load a private font, using System.Drawing.Text.PrivateFontCollection. The goal is not to have to install the font on the system.

All the examples i find it look pretty simple. Just load using PrivateFontCollection and then create a font from it.

Below my simple class to test it.

It works only if i install the font. In not, the text is printed in the dialog preview as using some default font. I checked that the font is correctly loaded. What i'm missing ? Thank for any 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 Be a bar code", _barCodeFont, Brushes.Black, 0, 0);
        ev.HasMorePages = false;
    }      
}

Answer 1

try this

 private void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
    Font _barCodeFont = new Font(privateFonts.Families[0], 12, FontStyle.Regular);
    ev.Graphics.DrawString("Should Be a bar code", _barCodeFont, Brushes.Black, 0, 0);
    ev.HasMorePages = false;
}    

and remove
private Font _barCodeFont;
