json传输图片 等二进制数据

最近项目中遇到需要json传输上百个图标

进行了多种二进制转String的尝试，最终转得的String完全不对

自己估计是编码格式问题，查找资源发现basic64专做二进制数组和String之间的装换，

将Byte与字符相互装换

以下是C#实现的 json可用的 图片转String String转图片 的代码

/// <summary>Convert bitmap to Base64 String /// </summary> /// <param name="bitmap"></param> /// <returns></returns> public static String Jpeg2String(Bitmap bitmap) { using (Stream stream = new System.IO.MemoryStream()) { bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg); stream.Seek(0, SeekOrigin.Begin); Byte[] picData = new byte[stream.Length]; stream.Read(picData, 0, picData.Length); String sbmp = System.Convert.ToBase64String(picData); return sbmp; } } /// <summary> Convert base64 String to Jpeg /// </summary> /// <param name="base64Str"></param> /// <returns></returns> public static Bitmap GetBitMap(String base64Str) { if (!String.IsNullOrEmpty(base64Str)) { using (Stream stream = new MemoryStream()) { byte[] picData = System.Convert.FromBase64String(base64Str); stream.Write(picData, 0, picData.Length); stream.Seek(0, SeekOrigin.Begin); Bitmap bitmap = new Bitmap(stream); return bitmap; } } return null; }
