C#求教如何获取字体的文件名
如题如宋体对应的是simsun.ttc
用C#如何获取 --------------------编程问答-------------------- 用IO查找Fonts文件夹 --------------------编程问答-------------------- 除 --------------------编程问答--------------------
我想知道的是"宋体"是如何关联上simsun.ttc
就是说我用FontDialog得到"宋体"这个名称后,然后我该如何去获得simsun.ttc这个系统文件名
有现成的函数或者方法吗?

查过了,没有找到 宋体名和simsun.ttc文件名的对应 --------------------编程问答-------------------- MSDN上2007年已经有人问过这个问题，如果你的英文还可以的话，可以看下地址：

解决方案在：http://www.codeproject.com/Articles/4190/XFont-Get-font-name-and-file-information
就是第一篇帖子最后一个人所说：It's not perfect, but it works.
Good Luck！ --------------------编程问答-------------------- 刚好我也需要这个功能，就一次回复到位吧。
以下C#代码可读取指定.ttf文件里的字体名，思路反过来：遍历<windir\>Fonts目录下的所有文件，即可找到通过“字体选择器”返回的字体名的字体文件。
虽然办法笨了点，但确实也没啥好办法，凑合着能用。
It's not perfect, but it works.

别说不会用这个例子啊，仔细看下代码就知道啦。 --------------------编程问答-------------------- 经测试，上面老外的方法不好用，不好意思
。自己写了个简单的，经测可用：
class FontNameFile
{
public static string getFontFileName(string fontname)
{
string folderFullName = System.Environment.GetEnvironmentVariable("windir") + "\\fonts";
DirectoryInfo TheFolder = new DirectoryInfo(folderFullName);
foreach (FileInfo NextFile in TheFolder.GetFiles())
{
if (NextFile.Exists)
{
if (fontname == getFontName(NextFile.FullName)) return NextFile.FullName;
}
}
return ("");
}
private static string getFontName(string fontfilename)
{
PrivateFontCollection pfc = new PrivateFontCollection();
try
{
pfc.AddFontFile(fontfilename);
}
catch (Exception ex)
{
return "";
}
return(pfc.Families[0].Name);
}
}
补充：.NET技术 , C#
