            SqlConnection myConn = new SqlConnection(database);
            SqlCommand Selectcommand = new SqlCommand("select * from loonberekening.tblInloggen where id = '" + this.txtGebruikersnaam.Text + "' and passwoord= '" + this.txtPaswoord.Text + "' ;", myConn);
            SqlDataReader myReader;
            myConn.Open();
            myReader = Selectcommand.ExecuteReader();
            int count = 0;
            while (myReader.Read())
            {
                count = count + 1;
            }
            if (count == 1)
            {
                MessageBox.Show("Gebruikersnaam en paswoord is correct");
                startmenu.ShowDialog();
            }
            else if (count > 1)
            {
                MessageBox.Show("Dit is een gedupliceerde paswoord en gebruikersnaam... Acces verboden");
            }
            else
            {
                MessageBox.Show("Username and paswoord zijn niet correct, Probeer opnieuw");
                myConn.Close();
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

Answer 1

Change the order in your connection it should be Initial catalog first before the integrated security

SqlConnection con = new SqlConnection(@"DataSource=sadf;Initial Catalog=asdf;Integrated Security=TRUE");

Answer 2

如果您的数据库文件附加在中，请尝试此操作SSMS

string database = @"Data Source=.; Integrated Security; 
                  Initial Catalog=loonberekening; Connect Timeout=30;"

如果您想要具有特定数据文件的 LocalDB 自动实例，那么

string database = @"Server=(localdb)\v11.0;Integrated Security=true; 
                  AttachDbFileName=E:\gip_stap_2\loonberekening.mdf;"

注意： 在loonberekening.dbo.tblInloggen你loonberekening.tblInloggen的Select Statement

像这样的东西

SqlCommand Selectcommand = 
new SqlCommand("select * from loonberekening.dbo.tblInloggen where id = '" +
 this.txtGebruikersnaam.Text + "' and passwoord= '" + this.txtPaswoord.Text + "' ;", myConn);
