C#將http路徑圖片轉爲byte字節數據

輸入圖片Http地址，即可返回byte[] bytes

		public static byte[] Url_To_Byte(String filePath)
        {
            //第一步：讀取圖片到byte數組
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(filePath);

            byte[] bytes;
            using (Stream stream = request.GetResponse().GetResponseStream())
            {
                using (MemoryStream mstream = new MemoryStream())
                {
                    int count = 0;
                    byte[] buffer = new byte[1024];
                    int readNum = 0;
                    while ((readNum = stream.Read(buffer, 0,1024)) > 0)
                    {
                        count = count + readNum;
                        mstream.Write(buffer, 0, readNum);
                    }
                    mstream.Position = 0;
                    using (BinaryReader br = new BinaryReader(mstream))
                    {
                        bytes = br.ReadBytes(count);
                    }
                }
            }
            return bytes;


        }
