通过 html 搜索的 C# 脚本 [关闭]

Question

我正在尝试使用 C# 编写代码，该代码逐行读取具有两个字段（用户 ID、跟踪 ID）的访问数据库，并在以下 url 中设置每个用户 ID（将标签替换为用户 ID）：

http://abcdef.comghijklmnopqrstuvwxyz<userid>?groups=<userid>

并搜索网页上显示的数据（数据为JSON格式）。如果出现与User ID同一记录的Track ID，则计数器加1。

namespace test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            OleDbConnection conn = new OleDbConnection();
            conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\hidden.accdb";
            conn.Open();
            OleDbCommand cmd = new OleDbCommand();
            cmd.Connection = conn;
            cmd.CommandText = "Select * from hidden.accdb";
            DataTable dt = new DataTable();
            //To read data from dataset
            OleDbDataAdapter adapter = new OleDbDataAdapter();
            adapter.SelectCommand = cmd;
            //Store the UserID
            adapter.Fill(dt);
            conn.Close();
        }

        private void btn_run_Click(object sender, EventArgs e)
        {

            int UserID;
            int TrackID;
            int counter=0;
            for (int ID = 1; ID <= 2916; ID++)
            {

                string url = "http://abcdef.com/ghijklmnopqrstuvwxyz<userid>?groups=<userid>";
                string test = test.Replace("i", Convert.ToString(UserID));
                System.Diagnostics.Process.Start(url);
                string client = (new WebClient()).DownloadString("http://abcdef.com/ghijklmnopqrstuvwxyz<userid>?groups=<userid>");
                if (client.Contains(Convert.ToString(TrackID)))
                {
                    counter++;
                }
            }
int ave= counter/2916;
}
}
}

你需要做的

var test = url.Replace("<userid>",Convert.ToString(UserID));

这不是你想要的吗？
