Instead of dataGridView in C# windows application, what should I use for console application to display a table from sql server?

Question

Question as above. I was told to use list<> to do so, but I still have no clue about how to do it exactly. I am new to C#.

Answer 1

You could try something like the very simplified example below...

using System;
using System.Data;
using System.Data.SqlClient;

SqlConnection conn = new SqlConnection(***Your Connection String Here***);
conn.Open();

SqlDataAdapter adpt = new SqlDataAdapter("Select ID, Dish, Price From RestaurantMenu", conn);

DataTable dt = new DataTable();
adpt.fill(dt);

conn.Close();

foreach (DataRow dr in dt.Rows){

     console.WriteLine(dr["ID"].ToString() + " | " + dr["Dish"].ToString() + " | " + dr["Price"].ToString());

}

Answer 2

Doing what jradich1234 did is the most practical approach. You fill a dataset with the table data and then just go through it printing each line and then adding a \\n after the last column.

If you really want to use the list<> object (or you have to do it), then the proccess has a little more of work. Basically you have to create the list and then, instead of printing, you add a new item to the list that represents the row... and then you move through the list and do exactly the same jradich1234 did.

It is a good way to practice the use of lists and simple structs, but it is not as efficiend as the previous answer.
