Xamarin.Forms 无法转换 stream 中的 TTF 文件

Question

I'm working on Xamarin.Forms app with help of Syncfusion and want to add Cyrillic support in PDF drawing.I download ArialUnicodeMS.tff added the file in Shared Project in Resources folder and added Build Action Embedded Resource and also added [assembly: ExportFont("ArialUnicodeMS.ttf", Alias = "ArialUni")] in AssemblyInfo.cs . But Syncfusion Pdf Drawing want to access to the TTF file by Stream .

This is my code:

var assembly = IntrospectionExtensions.GetTypeInfo(typeof(EmbeddedFont)).Assembly;
Stream stream = assembly.GetManifestResourceStream("MyAppName.ArialUnicodeMS.ttf");
PdfFont font = new PdfTrueTypeFont(stream, 14);

But my string is always null . Where i'm getting wrong?

Answer 1

The resource is missing.

Most likely it is one of these 3 issues:

• the name "MyAppName.ArialUnicodeMS.ttf" has a typo.
• the resource is not embedded in the typeof(EmbeddedFont)).Assembly assembly.
• you have not set the parameter Build Action to Embedded Resource . This is part of the EmbeddedFont project and acts on the ArialUnicodeMS.ttf resource.

To verify which names are available, you can use:

string resourceNames = assembly.GetManifestResourceNames();

Answer 2

You could use the code below to get the stream from the Embeded resource.

   var assembly = Assembly.GetExecutingAssembly();
        var resourceName = "App28.Trashtalk.ttf";
        Stream stream = assembly.GetManifestResourceStream(resourceName);
