C# 根据Image获取图形扩展名

在把图形保存到MEMORY 或则数据库里..我们不知道应该是那种扩展名..例如把GIF保存到数据库里 并没有记录以前的GIF名称...

 

 

 

使用方法

 

  Image _SetImage = Image.FromStream(_Stream);

            string _ImageExtension = GetImageExtension(_SetImage);

            MessageBox.Show(_ImageExtension);

 

 

 

全部方法

 

 

   /// <summary>
        /// 根据图形获取图形的扩展名 [email protected] qq:116149
        /// </summary>
        /// <param name="p_Image">图形</param>
        /// <returns>扩展名</returns>
        public static string GetImageExtension(Image p_Image)
        {
            Type Type = typeof(ImageFormat);
            System.Reflection.PropertyInfo[] _ImageFormatList = Type.GetProperties(BindingFlags.Static | BindingFlags.Public);
            for (int i = 0; i != _ImageFormatList.Length; i++)
            {
                ImageFormat _FormatClass = (ImageFormat)_ImageFormatList[i].GetValue(null, null);
                if (_FormatClass.Guid.Equals(p_Image.RawFormat.Guid))
                {
                    return _ImageFormatList[i].Name;
                }
            }
            return "";
        }
