本文介绍如何使用C#将Base64编码的图片数据转换为字节数组，并将其存储到特定目录下的.png文件中。

         string path = System.IO.Directory.GetCurrentDirectory() + @"\POIImages\";

         Guid imgid = Guid.NewGuid();
         byte[] ImageByte = Convert.FromBase64String(pic);

       /// <summary>
        /// 存储图片
        /// </summary>
        /// <param name="ImageByte"></param>
        /// <returns></returns>
        public void SaveImage(byte[] ImageByte,Guid imgid,string path)
        {
            //string path = System.IO.Directory.GetCurrentDirectory() + @"\POIImages\";
            FileStream fileStream = null;
            FileInfo fileInfo = new FileInfo(path + imgid+".png");
            fileStream = fileInfo.OpenWrite();
            fileStream.Write(ImageByte, 0, ImageByte.Length);
            fileStream.Close();
        }
