"loginrand"名称在当前上下文中不存在

Question

我只是尝试为travian创建bot,我找到了一些登录代码

        //download html 
        WebClient client = new WebClient();
        client.Encoding = System.Text.Encoding.UTF8;
        string source = client.DownloadString(@"Http://" + server + "/login.php");
        source = source.Replace("\"", "");

        //search for user

        Regex rloginName = new Regex(@"name=login value=\w*");
        Match mloginName = rloginName.Match(source);
        if (mloginName.Success)
        {
            string loginName = mloginName.ToString().Replace(@"name=login value=", "");
        }

        //search for pass

        Regex rloginPassword = new Regex(@"type=password name=\w*");
        Match mloginPassword = rloginPassword.Match(source);
        if (mloginPassword.Success)
        {
            string loginPassword = mloginPassword.ToString().Replace(@"type=password name=", "");
        }

        Regex rloginUsername = new Regex(@"input class=fm fm110 type=text name=\w*");
        Match mloginUsername = rloginUsername.Match(source);
        if (mloginUsername.Success)
        {
            string loginUsername = mloginUsername.ToString().Replace(@"input class=fm fm110 type=text name=", "");
        }
        Regex rloginRand = new Regex(@"<p align=center><input type=hidden name=\w*");
        Match mloginRand = rloginRand.Match(source);
        if (mloginRand.Success)
        {
            string loginrand = mloginRand.ToString().Replace("<p align=center><input type=hidden name=", "");
        }

        string postString = @"w=1024:768&login=" + loginName + "&" + loginUsername + "=" + user + "&" + loginPassword + "=" + pass + "&" + loginrand + "=&s1.x=10&s1.y=10&s1=login";


        WebRequest req = WebRequest.Create(@"http://" + server + "/dorf1.php");
        req.ContentType = "application/x-www-form-urlencoded";
        req.Method = "POST";
        byte[] bytes = System.Text.Encoding.ASCII.GetBytes(postString);
        req.ContentLength = bytes.Length;
        req.ContentLength = bytes.Length;
        Stream os = req.GetRequestStream();
        os.Write(bytes, 0, bytes.Length);
        os.Close();
        WebResponse resp = req.GetResponse();
        StreamReader sr = new StreamReader(resp.GetResponseStream());

但当我试图运行时,我看到这个错误,

Form1.cs(67,144):错误CS0103:当前上下文错误CS0103中不存在名称'loginrand':当前上下文错误中不存在名称'loginPassword'错误CS0103:名称'loginUsername'不存在于当前上下文错误中当前上下文错误CS0103:当前上下文中不存在名称"loginName"

可以帮助一些人

string loginrand; if(mloginRand.Success){loginrand = mloginRand.ToString().替换("

但没有变化:(

1. 不要烦恼并为在线游戏创建机器人.
2. 了解变量作用域,在if语句中声明变量意味着变量在其外部不可用.

例如:

if (mloginPassword.Success)
{
    // variable defined here
    string loginPassword = 
        mloginPassword.ToString().Replace(@"type=password name=", "");
}
// variable not available here
