WPF Image控件显示网络图片

WPF Image控件显示网络图片。

xaml代码就贴一个Image控件：

<img height="100" horizontalalignment="Left" name="image" verticalalignment="Top" width="100" />

加载代码也很简单：

public ImportWindow()
{
   InitializeComponent();

   //图片地址的cookie
   string cookie = "abtest=20170731114831940_65; mobilev=html5; downloadAppPlugIn_downCloseDate=1501473077298_86400000; guid=5786acf72feafd33a77eae9d9e475f39240b9e2d66b01848fe32886f8bc35b9b; shshshfpa=6563e0d9-1cec-0905-8c8f-1066978c7deb-1501473091; whwswswws=U6%2F4jUQFaa%2FLOnmIhn9mEM4lbCRoOqUXtpqaoxofJWhAp7SX6tDsOA%3D%3D; _jrda=1; TrackID=1LniGEEJTwAeWZoQVZcYPveu1zfMu2KFp3P9eOmsTDkaVJDNi2_k3dfUOt3OESuaTOmtFx6L0sBelTdp15kHkLp8bZx1hr7wzJeayWKUSZGk; pinId=FVd6lGAhM3h5HUZeAIYtf7V9-x-f3wj7; pin=jd_78e874d39dc63; unick=52005wpm; _tp=oxWZIWBwtDdSQnvZlRT9LIGj6fHnC1PW3J3xQyQl8vE%3D; _pst=jd_78e874d39dc63; unpl=V2_YDNtbUdQQUF9AREGfklcDGJRQFgSU0sddQpEAXsdXgVgAhtcclRCFXMUR11nGV0UZwMZWEpcQxVFCHZXfBpaAmEBFl5yBBNNIEwEACtaDlwJARRZRFNLFHIITl1LKV8FVwMTbUFfSxd0CkBcfylsAlczIl1EVEYRcjhHZHopHlE7ChRbQ1RKWHYATlZ6G1oNYzMTbUE%3d; __jdv=122270672|baidu-search|t_262767352_baidusearch|cpc|37575906198_0_463e98fc4a184cc4a599133d15316080|1502336952636; ipLoc-djd=1-72-2799-0; mt_xid=V2_52007VwAaWl9ZUFwXTSkMBGcERVBVX04NSx4aQAAwU0FOVQxWDQMbS1RWZlcaBQ1dB1kvShhcA3sCG05dWUNaH0IdXg5iBSJQbVhiWhxMEF4NYAUVYl5fWw%3D%3D; 3AB9D23F7A4B3C9B=IXJUEDXXYNUG6YED62OKBVQ7LGRQHMPTR44MH5CS75ECUCXMCIFCVTJCVKEOAUPXO5MC76L3OFA6NWVPAWT2CLCT3Q; lang=chs; lsid=5yb07crf3okz7by6v7n246dpmj8rbyog; shshshfp=247fe600c03c6e1e5d914b644d1c5817; shshshfpb=2e31dd5ae7fb5492c947e9d848612d70059712bf1e562a5e3b5fea8a62; TrackerID=vBSkTyNabO1W4xOuPi66E92jIxYTNbLQrECILCPcrJNnVhVYl7wntHbYC2ux6WWGrwv51YbzK-M2jKipw8Cr0Mk2_jJ_RI6lzfweqFZwf2E; pt_key=AAFZjTcPADDteQHoF0AUJFKRoBsq3nL6PaX0eBWwAqCNyaQUIeIXHGCy34_RF20ZKFIoMDjRMYs; pt_pin=anonymous-Aurora; pt_token=yv25cjar; pwdt_id=anonymous-Aurora; s_key=AAFZjTcPADCpEqUIKjw0GciUkBPIITTz-CykL5nF3whyYCsf_OdseiGdv2bd3mqFPEIOBhwWXBw; s_pin=anonymous-Aurora; USER_FLAG_CHECK=42a27536f20a85ccda959e2657f1b6bf; returnurl=\"https://m.jd.com?indexloc=1&sid=eca9ca08f981eaa929465178790539f0\"; m_uuid_new=559EE0955CDF39C603C8C45043D2708D; __jda=122270672.299303795.1501033309.1502336953.1502426875.4; __jdc=122270672; __jdu=299303795; autoOpenApp_downCloseDate_auto=1502426897076_1800000; sid=eca9ca08f981eaa929465178790539f0; recommendShow=show; mba_muid=299303795";
