Insert into database c# connection string error

Question

i am encountering an error when trying to set up an insert command into my database, it appears to be with the connection string. I am extremely new to all this and am trying to get the correct code in order to upload into my database and assume that the syntax i am using may be wrong and the cause of the error.

Here is the code a little bit clearer:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;

namespace ComputingProjectwh.TestPages._1._Further_Mechanics
{
    public partial class Moments_and_Energy_Test1 : System.Web.UI.Page
    {


        protected void Page_Load(object sender, EventArgs e)
        {

        }
        protected void Submit_Click(object sender, EventArgs e)
        {
            if (!this.IsValid)
                return;
            int score = 0;
            List<RadioButtonList> list = new List<RadioButtonList>() { RadioButtonList1, RadioButtonList2, RadioButtonList3, RadioButtonList4, RadioButtonList5, RadioButtonList6, RadioButtonList7, RadioButtonList8, RadioButtonList9, RadioButtonList10 };
            foreach (var element in list)
            {
                if (element.SelectedValue == "Correct")
                {
                    score++;
                }

            }
            Response.Write("you scored: " + score);
            Button1.Visible = false;

            if (score != 0);
            {
                SqlConnection sqlConnection1 = new SqlConnection (@"Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-ComputingProjectwh-20170404101246.mdf;InitialCatalog=aspnet-ComputingProjectwh-20170404101246;IntegratedSecurity=True");

                System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand();
                cmd.CommandType = System.Data.CommandType.Text;
                cmd.CommandText = "INSERT AspNetUserTestScores (Id, MomentAndEnergyTestScore) VALUES (Id, score)";
                cmd.Connection = sqlConnection1;

                sqlConnection1.Open();
                cmd.ExecuteNonQuery();
                sqlConnection1.Close();


            }

        }
    }
}

I am really not sure what the problem is and cant seem to find an answer on the internet. Any help would be greatly appreciated.

Answer 1

When connecting to MSSQL, there is no initialcatalog , You are using a wrong connection string.

This is the correct syntax:

  Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;

Or in your case, for trusted connection:

  Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;

With your data:

 SqlConnection sqlConnection1 = new SqlConnection("Server=LocalDb;Database=aspnet-ComputingProjectwh-20170404101246.mdf;Trusted_Connection=True;");

Answer 2

InitialCatalog是两个单独的单词initial catalog 。
