SQL Server和Model之間的手動連接

Question

我在ASP.Net中創建了一個空項目，然後手動添加了它的視圖，控制器和模型。現在我想將SQL Server連接到Model類。我該怎麼做 ？

Answer 1

try with this code, this code contain select query for just example  

    // Is your string connection to your database and server 
    string connectionString = ""; //connection to your database 

     //Create a connection to your database 
     //using bloc , in order to destruct connection object in the end of treatment 
     using (SqlConnection connection = new SqlConnection(connectionString)) 
     { 

      //Create object command who contain your query sql, permit you to get data or  //insert on update or delete data 
      using (SqlCommand command= connection.CreateCommand()) 

       { 
        //for example a query, who select data from table in your databse, 
        command.CommandText = "SELECT * FROM Table where col = @ParameterTest"; 
        //for exxample a parameter for your query 
        command.Parameters.Add("@ParameterTest", 123); //your test value 


        //after create connection you must open this 
        command.Connection.Open(); 
        //get data in reader, structure for readin datas 
        var reader = command.ExecuteDataReader(); 


       } 
     }
