convert font to string and back again
提问by jay_t55
i have an application where my user changes font and font color for different labels etc and they save it to a file but i need to be able to convert the font of the specified label to a string to be written to file, and then when they open that file my program will convert that string back into a font object. How can this be done? I haven't found anywhere that shows how it can be done.
我有一个应用程序，我的用户可以在其中更改不同标签等的字体和字体颜色，并将其保存到文件中，但我需要能够将指定标签的字体转换为要写入文件的字符串，然后当他们打开那个文件，我的程序会将该字符串转换回字体对象。如何才能做到这一点？我还没有找到任何显示它如何完成的地方。
thank you

It is easy to go back and forth from a font to a string and back with the System.Drawing.FontConverter class. For example:
使用 System.Drawing.FontConverter 类可以轻松地在字体和字符串之间来回切换。例如：
var cvt = new FontConverter();
string s = cvt.ConvertToString(this.Font);
Font f = cvt.ConvertFromString(s) as Font;

First, you can use following article to enumerate system fonts.
首先，您可以使用以下文章来枚举系统字体。
public void FillFontComboBox(ComboBox comboBoxFonts)
{
// Enumerate the current set of system fonts,
// and fill the combo box with the names of the fonts.
foreach (FontFamily fontFamily in Fonts.SystemFontFamilies)
{
// FontFamily.Source contains the font family name.
comboBoxFonts.Items.Add(fontFamily.Source);
}
comboBoxFonts.SelectedIndex = 0;
}
To create a font:
创建字体：
Font font = new Font( STRING, 6F, FontStyle.Bold );
Use it to setup font style etc....
用它来设置字体样式等....
Label label = new Label();
. . .
label.Font = new Font( label.Font, FontStyle.Bold );

You can serializethe font class to a file.
您可以将字体类序列化为文件。
See this MSDN articlefor details of how to do so.
To serialize:
序列化：
private void SerializeFont(Font fn, string FileName)
{
using(Stream TestFileStream = File.Create(FileName))
{
BinaryFormatter serializer = new BinaryFormatter();
serializer.Serialize(TestFileStream, fn);
TestFileStream.Close();
}
}
And to deserialize:
并反序列化：
private Font DeSerializeFont(string FileName)
{
if (File.Exists(FileName))
{
using(Stream TestFileStream = File.OpenRead(FileName))
{
BinaryFormatter deserializer = new BinaryFormatter();
Font fn = (Font)deserializer.Deserialize(TestFileStream);
TestFileStream.Close();
}
return fn;
}
return null;
}

Use this code to create a font based on the name and color information:
使用此代码根据名称和颜色信息创建字体：
Font myFont = new System.Drawing.Font(<yourfontname>, 9.75F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
Color myColor = System.Drawing.Color.FromArgb(<yourcolor>);

Quite simple really if you want to make it readable in the file:
如果你想让它在文件中可读，真的很简单：
class Program
{
static void Main(string[] args)
{
Label someLabel = new Label();
someLabel.Font = new Font("Arial", 12, FontStyle.Bold | FontStyle.Strikeout | FontStyle.Italic);
var fontString = FontToString(someLabel.Font);
Console.WriteLine(fontString);
File.WriteAllText(@"D:\test.txt", fontString);
var loadedFontString = File.ReadAllText(@"D:\test.txt");
var font = StringToFont(loadedFontString);
Console.WriteLine(font.ToString());
Console.ReadKey();
}
public static string FontToString(Font font)
{
return font.FontFamily.Name + ":" + font.Size + ":" + (int)font.Style;
}
public static Font StringToFont(string font)
{
string[] parts = font.Split(':');
if (parts.Length != 3)
throw new ArgumentException("Not a valid font string", "font");
Font loadedFont = new Font(parts[0], float.Parse(parts[1]), (FontStyle)int.Parse(parts[2]));
return loadedFont;
}
}
Otherwise serialization is the way to go.
否则序列化是要走的路。
