怎么样编程实现自动登陆？

Question

可以参考一下这个例子，QUICKSTART中的
using System;
using System.Net;
using System.IO;
using System.Text;
using System.Web;class ClientPOST {
    public static void Main(string[] args) {        if (args.Length < 1) {
            showusage();
        } else {
            if (args.Length < 2 ) {
                getPage(args[0], "s1=food&s2=bart");
            } else {
                getPage(args[0], args[1]);
            }
        }        Console.WriteLine();
        Console.WriteLine("Press any key to continue...");
        Console.ReadLine();        return;
    }    public static void showusage() {
        Console.WriteLine("Attempts to POST into to a URL");
        Console.WriteLine();
        Console.WriteLine("Usage:");
        Console.WriteLine("ClientPOST URL [postdata]");
        Console.WriteLine();
        Console.WriteLine("Examples:");
        Console.WriteLine("ClientPOST http://www.microsoft.com s1=food&s2=bart");
    }    public static void getPage(String url, String payload) {
        WebResponse result = null;        try {            WebRequest req = WebRequest.Create(url);
            req.Method = "POST";
            req.ContentType = "application/x-www-form-urlencoded";
    StringBuilder UrlEncoded = new StringBuilder();
    Char[] reserved = {'?', '=', '&'};
    byte[] SomeBytes = null;     if (payload != null) {
int i=0, j;
while(i<payload.Length){
    j=payload.IndexOfAny(reserved, i);
    if (j==-1){
UrlEncoded.Append(HttpUtility.UrlEncode(payload.Substring(i, payload.Length-i)));
break;
    }
    UrlEncoded.Append(HttpUtility.UrlEncode(payload.Substring(i, j-i)));
    UrlEncoded.Append(payload.Substring(j,1));
    i = j+1;
}
SomeBytes = Encoding.UTF8.GetBytes(UrlEncoded.ToString());
                req.ContentLength = SomeBytes.Length;
                Stream newStream = req.GetRequestStream();
newStream.Write(SomeBytes, 0, SomeBytes.Length);
                newStream.Close();
            } else {
                req.ContentLength = 0;
            }
            result = req.GetResponse();
            Stream ReceiveStream = result.GetResponseStream();
         Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
         StreamReader sr = new StreamReader( ReceiveStream, encode );
            Console.WriteLine("\r\nResponse stream received");
            Char[] read = new Char[256];
         int count = sr.Read( read, 0, 256 );
            Console.WriteLine("HTML...\r\n");
            while (count > 0) {
        String str = new String(read, 0, count);
                Console.Write(str);
                count = sr.Read(read, 0, 256);
            }
            Console.WriteLine("");
        } catch(Exception e) {
        Console.WriteLine( e.ToString());
            Console.WriteLine("\r\nThe request URI could not be found or was malformed");
        } finally {
            if ( result != null ) {
                result.Close();
            }
        }
    }
}

Answer 1

可以操作注册表实现。步骤如下
1． 开始-〉运行 –〉Regedit.
2.到下面的注册表： HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon
3． 在 Winlogon健值中，添加一个注册表值名为 “DefaultUserName”, 类型为 String,并把它的值设为你的用户名。
4． 再添加一个值名为 “DefaultPassword”, 类型为String，把它的值设为你的密码。
5．  再添加一个值名为 “AutoAdminLogon”, 类型为String，把它的值设为1
6． 关闭注册表编辑器并重启电脑。
