c# 读取图片文件

        /// <summary>
        /// 通过FileStream 来打开文件,这样就可以实现不锁定Image文件,到时可以让多用户同时访问Image文件

        public static Bitmap ReadImageFile(string path)

            int filelength = 0;
            filelength = (int)fs.Length; //获得文件长度 
            Byte[] image = new Byte[filelength]; //建立一个字节数组 
            fs.Read(image, 0, filelength); //按字节流读取 
            System.Drawing.Image result = System.Drawing.Image.FromStream(fs);
            fs.Close();
            Bitmap bit = new Bitmap(result);
            return bit;
        }
