标签:[] position save rom 图片 string 对象 oba 转换
在C#中 图片到byte[]再到base64string的转换: Bitmap bmp = new Bitmap(filepath); MemoryStream ms = new MemoryStream(); bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Gif); byte[] arr = new byte[ms.Length]; ms.Position = 0; ms.Read(arr, 0, (int)ms.Length); ms.Close(); string pic = Convert.ToBase64String(arr); base64string到byte[]再到图片的转换: byte[] imageBytes = Convert.FromBase64String(pic); //读入MemoryStream对象 MemoryStream memoryStream = new MemoryStream(imageBytes, 0, imageBytes.Length); memoryStream.Write(imageBytes, 0, imageBytes.Length); //转成图片 Image image = Image.FromStream(memoryStream); 现在的数据库开发中:图片的存放方式一般有CLOB:存放base64string,BLOB:存放byte[]
