I have a program that has to loop through a Scenarios database, and for each while loop iteration, update a second Results database. Here's the segment of code.

    public void TestScenarios(SqlConnection connection)
    {
        using (SqlCommand cmd = new SqlCommand("SELECT * FROM Scenarios", connection))
        {
            SqlDataReader reader = cmd.ExecuteReader();

            if (reader.HasRows)
            {
                while (reader.Read())
                {
                    string Id = reader["ScenarioID"].ToString();
                    string Data = reader["ScenarioData"].ToString();
                    string Url = reader["ScenarioURL"].ToString();
                    webBrowser1.Navigate(Url);
                    InsertResults(connection, Id);
                }
            }

            reader.Close();
        }
    }

    public void InsertResults(SqlConnection conn, string Id)
    {
        using (SqlCommand cmd = new SqlCommand("INSERT INTO Results VALUES(" +
                "@ResultID, @HasSucceeded, @ScenarioID, @Screenshot)", conn))
        {
            cmd.Parameters.AddWithValue("@ResultID", 0);
            cmd.Parameters.AddWithValue("@HasSucceeded", 0);
            cmd.Parameters.AddWithValue("@ScenarioID", Id);
            cmd.Parameters.AddWithValue("@Screenshot", "screenshot.jpeg");
        }
    }

It's not working, and I'm sure I did tons of things wrong, but I'm having trouble finding direction.

您的第二个命令永远不会执行。添加：

cmd.ExecuteNonQuery();

我可以建议您使用 SqlBulkCopy 吗？这里有一些关于如何复制两个数据库表的信息，希望你能看清楚。
