如何将值从窗体窗体应用发送到asp.net服务器并从中获取值窗体数据库？

Question

I want user to get the user name and password in the windows form the send it to a web form for the verification, where after verification from the database the entries(which are courses joint by the user) are sent back to the window form, I searched alot but could not get any suitable method, I am new ti c# and asp.net.. I found a way here I am placing my code please tell me is there any better way to do my job.but instead of getting the desired values i get the whole html code so i used to enclose my desired value in html tags on server side which and on client side I am getting the values by using the regular expressions Here is code for windows from which sends after getting values from the text boxes

 try
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(@"http://localhost:50612/Inclusive_LMS/speech/login.aspx/?stdId=" +tb_stdId.Text + "&pass=" + tb_pass.Text);
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            string content = new StreamReader(response.GetResponseStream()).ReadToEnd();

            Match valid = Regex.Match(content, @"(?<=(<span[^>]*>))([^<]*)(?=(</span>))");

            if (valid.Success)
            {
                this.Hide();
                Student_dashboard ins = new Student_dashboard();
                ins.Show();
            }
            else
            {
                MessageBox.Show("invalid user Id or password");

            }


           // textBox2.Text = "" + content + "";
        }
        catch (Exception ex)
        {
            MessageBox.Show("check your internet connection, failed to connect the server.");

        }

Here is the code for " http://localhost:50612/Inclusive_LMS/speech/login.aspx " page,on designer side I had only one lable on html page

    SqlDataReader r;
    SqlCommand cmd = new SqlCommand("Select * from Student where Std_Id='" +Convert.ToInt32(Request.QueryString["stdId"]) + "' and Password='" +Request.QueryString["pass"]+ "'", con);
   try
   {
    con.Open();
        r = cmd.ExecuteReader();
        if (r.Read())
            Label1.Text = "success";
        else
            Label1.Text = "fail";
        con.Close();
     }
      catch
      {
          Label1.Text = "error";
      }

I guess, the best approach would be to access the database directly from the windows application (If it is possible) for any task.

If it is not possible for you to access database directly, you can create a web service in your webform project and consume it in the winforms application. This is easy to implement and works well.

The third approach is to use WebAPI in ASP.NET framework for doing this task.

You need to choose what fits best in your scenario. Best of luck!
