将图像路径转换为base64字符串

尝试这个

using (Image image = Image.FromFile(Path)){    using (MemoryStream m = new MemoryStream())    {        image.Save(m, image.RawFormat);        byte[] imageBytes = m.ToArray();        // Convert byte[] to base64 String        string base64String = Convert.Tobase64String(imageBytes);        return base64String;    }}
