识别:CSDN验证码识别取图像部分,ASP.NET_SessionID=这个值你要自己取这样
话就可以做成自动登录了private Stream geturl(ref
str){
url = "http://www.csdn.net/member/ShowExPwd.aspx";WebRequest myWebRequest = WebRequest.Create(url);
myWebRequest.Headers.Add("Cookie","ASP.NET_SessionId=tr0p4g45xa0qzg45bmlqprnn");
WebResponse myWebResponse = myWebRequest.GetResponse
;Stream ReceiveStream = myWebResponse.GetResponseStream
; str=myWebResponse.Headers[6];
ReceiveStream;}
private
getNumber{
str;str="";
Stream geturlStream =geturl(ref str);
Bitmap map =
Bitmap(geturlStream,false);pictureBox1.Image = (Image)map;
csdn csdn1=
csdn ; csdn1.readMap(map)+str;}
验证码识别部分(很简单类型
): 分割图片变成 4个部分.
接下来判断象素点.再判断特征点 100%识别
