Does anyone know how to create pdf from base64 string and show in xamarin forms ?


Hi all,

Does anyone know how to display base64 string to webview in Xamarin forms and then I need to download this base64 string in pdf file.

    Read the string and save it as a local file. Then open the pdf file using a webView. The WebView control can display PDF files on the iOS platform, but not on the Android and Windows Phone platforms due to lack of platform support. You could achieve the reading function in native using DependencyService.

    byte[] byteBuffer = Encoding.UTF8.GetBytes(pdfString);
    public string SaveBinary(string filename, byte[] bytes)
        string filepath = GetFilePath(filename);
        if (File.Exists((filepath)))
        File.WriteAllBytes(filepath, bytes);
        return filepath;
    string GetFilePath(string filename)
        return Path.Combine(GetPath(), filename);
    string GetPath()
        return System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments);
