本文主要向大家介绍了C#编程之C#根据字体名通过注册表获取该字体文件路径(win10)，通过具体的内容向大家展示，希望对大家学习C#编程有所帮助。

方法一:
直接先上源码:

        private System.Collections.Generic.SortedDictionaryReadFontInformation()
        {
            var dictionary = new System.Collections.Generic.SortedDictionary();

          
                Microsoft.Win32.RegistryKey localMachineKey = Microsoft.Win32.Registry.LocalMachine;
                // 打开注册表 
                Microsoft.Win32.RegistryKey localMachineKeySub = localMachineKey.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Fonts", false);

                //获取字体名 
                string[] mynames = localMachineKeySub.GetValueNames();

                foreach (string name in mynames)
                {
                    //获取字体的文件名 
                    string myvalue = localMachineKeySub.GetValue(name).ToString();

                    if (myvalue.Substring(myvalue.Length - 4).ToUpper() == ".TTF" && myvalue.Substring(1, 2).ToUpper() != @":\")
                    {
                        string val = name.Substring(0, name.Length - 11);
                        dictionary[val] = myvalue;
                    }
                }
            localMachineKeySub.Close();
            return dictionary;
        }

 解决思路:
1. 打开windows/fonts目录, 右键下图, 勾选字体文件名称, 发现其实字体文件名称和显示的名称是有区别的

2. 然后去注册表中看看, win+r→regedit, 定位  LocalMachine \\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Fonts 可以看到, 对应的键值对

3. 既然有思路了, 就开始操作注册表, 注意, 如果在win7以上的系统中, 将localMachineKey.OpenSubKey("",true)第二个参数设置为true, 在xp下没有问题, 在win7以上就会报以下错误:

4. 解决此错误的方法是增加应用程序配置清单文件, 然后做下面的修改, 但是在运行的时候, 会提示要求用管理员权限(提权). 全部代码和清单文件内容如下:

//[System.Security.Permissions.RegistryPermissionAttribute(System.Security.Permissions.SecurityAction.PermitOnly, Read = @"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts")]// 约束代码仅可读注册表
        private System.Collections.Generic.SortedDictionaryReadFontInformation()
        {
            var dictionary = new System.Collections.Generic.SortedDictionary();

          
                Microsoft.Win32.RegistryKey localMachineKey = Microsoft.Win32.Registry.LocalMachine;
                // 打开注册表 
                Microsoft.Win32.RegistryKey localMachineKeySub = localMachineKey.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Fonts", false);

                //获取字体名 
                string[] mynames = localMachineKeySub.GetValueNames();

                foreach (string name in mynames)
                {
                    //获取字体的文件名 
                    string myvalue = localMachineKeySub.GetValue(name).ToString();

                    if (myvalue.Substring(myvalue.Length - 4).ToUpper() == ".TTF" && myvalue.Substring(1, 2).ToUpper() != @":\")
                    {
                        string val = name.Substring(0, name.Length - 11);
                        dictionary[val] = myvalue;
                    }
                }
            localMachineKeySub.Close();
            return dictionary;
        }

 清单文件:

 方法二:直接拿对应的文件名:

public  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.Name;
                    }
                }
            }
            return "";
        }

        private static string getFontName(string fontfilename)
        {
            PrivateFontCollection pfc = new PrivateFontCollection();
            //只要ttf和TTF, 其它的本项目不需要
            if (fontfilename.EndsWith(".ttf") || fontfilename.EndsWith(".TTF"))
            {
                pfc.AddFontFile(fontfilename);
            }
            if (pfc.Families.Length > 0)
            {
                return pfc.Families[0].Name;
            }
            return "";
        }
    }
