Xamarin.Forms字体系列不适用于UWP

private void LoadCustomFonts()
{
    var customFontPath = "ms-appx:///Assets/Fonts/YourCustomFont.ttf"; // 替换为自定义字体文件的路径
    var customFontFamilyName = "YourCustomFontFamilyName"; // 替换为自定义字体的名称

    var customFont = new FontFamily(customFontPath);
    if (!customFont.FamilyNames.ContainsKey(customFontFamilyName))
    {
        customFont.FamilyNames.Add(customFontFamilyName, customFontPath);
    }

    // 将自定义字体应用于UWP应用程序
    Windows.UI.Xaml.Controls.TextBlock textBlock = new Windows.UI.Xaml.Controls.TextBlock();
    textBlock.FontFamily = new FontFamily(customFontFamilyName);
}

<Label Text="Hello, Xamarin.Forms!" FontFamily="YourCustomFontFamilyName" />
