系统::绘图::文本:: PrivateFontCollection不工作时，字体未安装

Question

我试图从内存（嵌入式资源）添加字体，并将其用于我的Windows窗体（C++/cli）应用程序...代码正在工作，但是当计算机上未安装指定的字体时，文本框将使用默认字体而不是我的自定义字体。 CompatibleTextRenderingDefault设置为true。

System::Drawing::Text::PrivateFontCollection^ privateFont = gcnew System::Drawing::Text::PrivateFontCollection(); 

    IO::Stream^ fontStream = Reflection::Assembly::GetExecutingAssembly()->GetManifestResourceStream("textfont.otf"); 
    array<Byte>^ fontData = gcnew array<Byte>(fontStream->Length); 
    fontStream->Read(fontData, 0, (int)fontStream->Length); 
    fontStream->Close(); 

    pin_ptr<byte> fontAddress = &fontData[0]; 
    privateFont->AddMemoryFont((IntPtr)fontAddress, fontData->Length); 

    this->TextBox_Username->Font = gcnew System::Drawing::Font(safe_cast<System::Drawing::FontFamily^>(privateFont->Families[0]), 9.749999F, System::Drawing::FontStyle::Bold); 
    this->TextBox_Password->Font = gcnew System::Drawing::Font(safe_cast<System::Drawing::FontFamily^>(privateFont->Families[0]), 9.749999F, System::Drawing::FontStyle::Bold);

两种方法（AddFontFile，AddMemoryFont）提供给字体加载到PrivateFontCollection不完全支持OpenType字体。改用TrueType字体。
