阅读windows字体

Question

将所有Windows字体读入 ComboBox 的最佳方法是什么？ 基本上，我试过这样做：

等于 Microsoft Word

我能做到：

 string[] fonts = Directory.GetFiles(@"C:\windows\fonts");

并将每个文件显示到 ComboBox 中，但这是正确的吗？有没有这样做的组件？

提前致谢。

Answer 1

查看EnumFontFamiliesEx和EnumFonts。

好多了InstalledFontCollection。我没有意识到它存在。

Answer 2

试试这个：

using System.Drawing.Text;

InstalledFontCollection myFonts = new InstalledFontCollection();
foreach (FontFamily ff in myFonts.Families)
  comboBox1.Items.Add(ff.Name);
}

Answer 3

Font文件夹中有一些.FON字体。 C＃不适用于那些BITMAP字体 - 您无法使用抽象字符串函数显示这些字体。要获取您可以显示的所有字体，只需使用我在此处找到的代码： http://www.java2s.com/Code/CSharp/GUI-Windows-Form/Getallsysteminstalledfont.htm

   using System;
   using System.Drawing;
   using System.Drawing.Text;
   using System.Collections;
   using System.ComponentModel;
   using System.Windows.Forms;
   using System.Data;        


   public class Test{
        static void Main() 
        {
          InstalledFontCollection fonts = new InstalledFontCollection();
          for(int i = 0; i < fonts.Families.Length; i++)
          {
            Console.WriteLine(fonts.Families[i].Name);
          }
        }
      }

您可以创建自动加载Windows已安装字体的自定义控件：

namespace MyProject
{   
    public class FontComboBox : ComboBox
    {
        public FontComboBox()
        {               
            MaxDropDownItems = 20;
            IntegralHeight = false;
            Sorted = false;
            DropDownStyle = ComboBoxStyle.DropDownList;
            DrawMode = DrawMode.OwnerDrawVariable;                          
        }

        public void Populate(bool b)
        {
            both = b;
            foreach (FontFamily ff in FontFamily.Families)
            {
                if(ff.IsStyleAvailable(FontStyle.Regular))
                    Items.Add(ff.Name);                                             
            }           

            if(Items.Count > 0)
                SelectedIndex=0;
            //ttimg = new Bitmap(GetType(),"ttfbmp.bmp");
            ttimg = new Bitmap(Resources.ttfbmp);
        }

        protected override void OnMeasureItem(System.Windows.Forms.MeasureItemEventArgs e)
        {   
            if(e.Index > -1)
            {
                int w = 0;
                string fontstring = Items[e.Index].ToString();                      
                Graphics g = CreateGraphics();
                e.ItemHeight = (int)g.MeasureString(fontstring, new Font(fontstring,10)).Height;
                w = (int)g.MeasureString(fontstring, new Font(fontstring,10)).Width;
                if(both)
                {
                    int h1 = (int)g.MeasureString(samplestr, new Font(fontstring,10)).Height;
                    int h2 = (int)g.MeasureString(Items[e.Index].ToString(), new Font("Arial",10)).Height;
                    int w1 = (int)g.MeasureString(samplestr, new Font(fontstring,10)).Width;
                    int w2 = (int)g.MeasureString(Items[e.Index].ToString(), new Font("Arial",10)).Width;
                    if(h1 > h2 )
                        h2 = h1;
                    e.ItemHeight = h2;
                    w = w1 + w2;
                }
                w += ttimg.Width*2;
                if(w > maxwid)
                    maxwid=w;
                if(e.ItemHeight > 20)
                    e.ItemHeight = 20;
            }



            base.OnMeasureItem(e);
        }

        protected override void OnDrawItem(System.Windows.Forms.DrawItemEventArgs e)
