回答1:

Easy way is just rendering a TextBlock with the text on a WriteableBitmap

private void RenderString(WriteableBitmap bitmap, string stringToRender)
{
    TextBlock textBlock = new TextBlock();
    textBlock.Text = stringToRender;

    // set font, size, etc. on textBlock

    bitmap.Render(textBlock, null);
    bitmap.Invalidate();
}
