网站自动注册（winform、webBrowser)

  private void webBrowser1_DocumentCompleted_1(object sender, WebBrowserDocumentCompletedEventArgs e)
        {

            if (webBrowser1.Url.ToString() == "http://xxxxx/xxxx.xxx.cn/")
            {
                StreamReader sr = new StreamReader(Application.StartupPath + "\\cont.txt");
                i = int.Parse(sr.ReadLine().ToString());
                string name = "";
                sr.Close();
                HtmlDocument doc = webBrowser1.Document;
                HtmlElement btn = null;
                foreach (HtmlElement em in doc.All)
                {
                    string str = em.Name;
                    switch (str)
                    {
                        case "email": { em.SetAttribute("value", "aajyjc" + i.ToString()); name = "gzjyj" + i.ToString(); }; break;
                        case "passwd": em.SetAttribute("value", "111111"); break;
                        case "againpasswd": em.SetAttribute("value", "111111"); break;
                        case "question": em.SetAttribute("value", "1"); break;
                        case "answer": em.SetAttribute("value", "呜呜呜呜"); break;
                        case "birthday": em.SetAttribute("value", "1987-10-05"); break;
                        case "pnickname": em.SetAttribute("value", "通天塔"); break;
                        case "securityemail": em.SetAttribute("value", "abc@def.com"); break;
                        case "ptruename": em.SetAttribute("value", "地方"); break;
                        case "idno": em.SetAttribute("value", getRandom2(System.DateTime.Now.Second)); break;
                        case "ppostcode": em.SetAttribute("value", getRandom1()); break;
                        case "ppostaddress": em.SetAttribute("value", "份额为服务俄方"); break;
                        case "FormSubmit": btn = em; break;
                        default: break;
                    }
                }
                i++;
                StreamWriter sw = new StreamWriter(Application.StartupPath + "\\cont.txt");
                sw.WriteLine(i);
                sw.Close();
                            }}

 

上面的代码是对网站里面要填的项进行自动填写。

下面是 用代理服务器登陆 代码 ，下面的代码不是自己写的，网上找的。

 

//这里是调用
WebBrowser wb = new WebBrowser();
WindowsFormsApplication1.proxy py1 = new proxy();
py1.RefreshIESettings("222.168.6.226:8080");
System.Object nullObject = 0;
string strTemp = String.Empty;
System.Object nullObjStr = strTemp;
wb.Navigate("http://xxxxx.com");
//这里是调用的类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

namespace WindowsFormsApplication1
{
    class proxy
    {

        public struct Struct_INTERNET_PROXY_INFO
        {
            public int dwAccessType;
            public IntPtr proxy;
            public IntPtr proxyBypass;
        };
        [DllImport("wininet.dll", SetLastError = true)]
        private static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength);
        
        public void RefreshIESettings(string strProxy)
        {
            const int INTERNET_OPTION_PROXY = 38;
            const int INTERNET_OPEN_TYPE_PROXY = 3;
            Struct_INTERNET_PROXY_INFO struct_IPI;
            // Filling in structure
            struct_IPI.dwAccessType = INTERNET_OPEN_TYPE_PROXY;
            struct_IPI.proxy = Marshal.StringToHGlobalAnsi(strProxy);
            struct_IPI.proxyBypass = Marshal.StringToHGlobalAnsi("local");
            // Allocating memory
            IntPtr intptrStruct = Marshal.AllocCoTaskMem(Marshal.SizeOf(struct_IPI));
            // Converting structure to IntPtr
            Marshal.StructureToPtr(struct_IPI, intptrStruct, true);
            bool iReturn = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY, intptrStruct, Marshal.SizeOf(struct_IPI));
        }
    }

}

 

下面是 遇见 网页中提交项 的自动提交实现代码

 

if (webBrowser1.Url.ToString() == "http://login.jyb.cn/user_mod.php")
            {
                HtmlDocument doc = webBrowser1.Document;
                foreach (HtmlElement em in doc.All)
                {

                    string str = em.Name;
                    switch (str)
                    {
                        case "mobile": { em.SetAttribute("value", getRandom3(System.DateTime.Now.Second)); }; break;

                        default: break;
                    }
                }
                HtmlElement form = this.webBrowser1.Document.Forms[0];
                form.InvokeMember("submit");
            }

 

随机用户名的代码（当然这里没有考虑，用户名的第一位不能为数字的情况）

 

 

  private string CreateRandomCode(int codeCount)
        {
            string allChar = "a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,0,1,2,3,4,5,6,7,8,9";
            string[] allCharArray = allChar.Split(',');
            string randomCode = "";
            int temp = -1;

            Random rand = new Random();
            for (int i = 0; i < codeCount; i++)
            {
                if (temp != -1)
                {
                    rand = new Random(i * temp * ((int)DateTime.Now.Ticks));
                }
                int t = rand.Next(35);
                if (temp == t)
                {
                    return CreateRandomCode(codeCount);
                }
                temp = t;
                randomCode += allCharArray[t];
            }
            return randomCode;
        }
